Results from TroubleShooting Low or No Suction Issues
2 Motor System With Low Suction
I have a Silent Master central vacuum that is a 2004 model. When I take the bag and filter out of the unit there are 2 circles in the bottom that look identical. One is working properly (you can feel proper air flow) and the other isn't (no airflow), resulting in low suction. Is that two motors and one isn't working? Right before this happened I noticed a burning smell. I was vacuuming up lots of baking soda at the time. Do I need to replace one of the motors? I did the troubleshooting chart and ended up at #8. Thanks, Deb Dallas,TX
Based on the information provided, it sounds like you will need to replace your motor. Depending on the model of Silent Master you have, you can find the correct replacement motor by clicking the following link: Silent Master Motor Options We recommend replacing both motors since they have the same amount of work hours on them and the other will likely end soon too.
Astro Vac No Suction All of A Sudden
I have a astro vac sr-50 and all of the sudden in between changing attachments the suction went out the power for the vac attachment still gets power but no suction
- Does your central vacuum activate with the manual on/off switch located on the side of the can? If so, please refer to #2 below. If not, the issue may be a result of a faulty circuit board or a faulty motor. Replacement Astro Vac SR50 Motors and Circuit Boards can be found on our website. Please refer to our Troubleshooting Flowchart to determine which item should be replaced.
- The switch in your hose handle failed. Please compare our Hose Switch Replacements to the switch inside of your hose handle.
Beam 750 No Suction
I have Beam central vacum system model 750 installed when mu house was built in 2005. It was working well until now when it lost its vacum suddenly. When I checked the outlet at the vacum drum itself it was working fine but all other wall outlet inside the home has no suction power. Thanks, Naveed.
Bucket Not Secure, Low Suction
cleaned the Kenmore central vac can not get the canister to seal tight /hangs slightly loose from the main body,any suggestions might be helpful,thanks.
Please ensure the canister gasket is in place for a secure fit.
Clogged Hose Repair
Glenna Hamiltion Ontario Canada
We have a Kenmore Mark 5 Central Vac which has low suction at the end of brush motor runs and has been replaced once I have tried suctioning marbles up they come back when I shake the hose it appears to me something is clogged in the hose unable to unclog this 50- to 100 ft hose would appreciated any suggestions you may have also tried to unclog with a large Shop Vac attached to hose TYVM Glenna
Unscrew a broom stick and feed it in through the wall end of the hose. It should stop at the clog and you can hold the stick and break the clog up. We have replacement hoses
, including 50ft hoses.
Cloth Filter Not in Right?
I have a ureka built in vaccum (not sure the model) and my husband accidently took off the cloth filter that hangs down when cleaning the unit but now we don't know how to put it back together and there is no suction (i am assuming because it is not put back together properly) thanks Elya Kelowna, BC
The cloth bag with stiff outer compression rim needs to sit inside the two grooves made for it. If it sits above the groove, it will clog the air intake to the motor. Flex the rim in and let it pop into the groove. The bag hangs down when not in use.
Cycling On and Off
We have an Air Vac 525 installed in 2000. The unit seems to cycle on and off. I have replaced the hose and filter. The screens become clogged and we clean periodically. The filter bag has debris inside the bag. Could the bag be installed incorrectly? or be the wrong size? it seems to fall into the canister.
The cycling on and off is generally caused by a faulty circuit board. Replacement circuit boards can be found on our website. The filter should have a weighted bottom and hang down a few inches. If the bag does not stay in place, please replace it with our center weighted cloth filter.
Dual Motor, No Suction
We have a nutone 11years old model cv-450 no suction from main system. checked all wires /all conected. Reset no response. Have dual motore, both working still no suction. Thanks Craig from WI
To get started, please disconnect the pipe(s) from the intake. Is there good suction from the unit alone? If so, please refer to Solution #3 on our Troubleshooting Flowchart
. If not, it could be an issue with the filter or a deteriorated gasket. Verify that the filter is not clogged or that the gasket has not been compromised.
Fasco Dirt Build-up Under Motor, Low Suction
I have a Fasco 851DM, after each vacuuming I have to remove a round dust patty from the screen closest to the motor or the suction will greatly diminish for the next use. There are no obstructions, filter is clean,so is canister. Unit is 10yrs, always worked fine. Why does this dust patty form on that screen now and never before. David, Prattville, Al
The Fasco should have an inverted cloth filter in it. If it is there, it means debris must be getting around it and you will need to replace the filter. Read the information listed below for further information on replacing the inverted cloth filter.
Important Information: Fasco has long been out of the central vacuum market and has no direct cloth bag replacements.
The black rubber gasket type is obsolete. You can either unstitch it and put the new cloth bag in the old rubber or you can buy similar rubber material and create your own. NOTE: There are no more gaskets available, from any vendors, that go on top of the bottom bucket.
Further Testing for Low Suction
I have an Electrolux unit, it came installed in house we just purchased (forclosed home). The unit has very little suction at the power unit (I followed your flowchart). I notice the pressure/volume coming out the exhaust is very good, but on the intake side you can barely feel any suction. What would my next step be? Everything seems sealed up good.
To get started, remove the filter located inside of the canister and test the system. Do you notice increased suction? If so, you will need to replace your filter with one of the Filter Options located on our website.
If you do not notice increased suction after removing the filter, disconnect the pipe that is connected to the intake on your unit and test the system. Hold your hand over the intake. Does the motor rev up? If not, the unit is leaking. Can you feel or hear any leaks around the can?
Access the motors located on the top of the unit. Do you see any excessive blue sparking? If so, your motor is failing and needs to be replaced with one of the Electrolux Motor Replacement Options located on our website.
Galaxie With Poor Suction
Hi I am Ben. My CV (Galaxie unit) is 9y old and used to work fine. Recently I found it has low sucktion. I thought it might need to empty the trash bag, then unplug the power and went head to empty the bottom basket, hooked it back on, plugged the power back. Sadly, it didn't improve the suction at all. Without the hose on, there is no suction on the inlet at all; plug the hose into the inlet, can hear the motor working, but still very low suction. Please help. Thanks!
Most Galaxie central vacuums are two-motor systems. When one fails, you will notice a significant decrease in power. You may view Galaxie Motor Replacement Options on our website.
If your motors are both functioning properly, your pipeline may clogged. Please read through our Troubleshooting Flowchart for tips on locating and removing clogs in your pipeline.
Hayden Suction Cuts Down
I have a Hayden 6000 super vac and initially the suction is great. In about one minute the unit goes to a low suction. It has occurred in all hose inlets. I have emptied the canister and cleaned the circular paper filter. Thank you
This issue is likely due to a faulty relay which can be remedied by replacing the electronics (relay, transformer, mini breaker) with our Generic Single Motor Circuit Board #235S. Please note that the mini-breaker and low voltage connection tower come with nuts that screw down and secure the board to the outside of the vacuum tank. If these two holes do not align with holes on the vacuum tank, a new hole will have to be drilled for proper mounting.
Hose Switch Not Activating The Vacuum Suction
i have a silent master central vac - the floor suction port in the kitchen works fine, but when i plug the hose into any outlet and flip the switch on the hose handle it will not turn on and there is no suction
The issue could be a result of a faulty switch in the handle or a short in the low voltage wires in the wall. Please follow our Troubleshooting Flowchart to narrow down the problem.
Initial Suction Okay, then Weak
I have a centra-clean CP 5000 unit. When we start the unit, the suction initially is strong, but then stops after one minute. Does this sound like a clog or a weak motor? Given the fact that the suction is initially strong, it doesn't seem like it could be a clog in the system. Thanks for your help
There are many potential causes for this issue: a clog, a faulty motor (if there are two motors), a broken pipe, or clogged filter. Please use this our Troubleshooting Flowchart to help pinpoint the culprit. You may also contact a Local Service Center for further assistance.
Kitchen Baseboard Vent Inlet Leaking?
This concerns a Stealth system. The suction is minimal and I wonder if what appears in the kitchen on the floor (a vent with suction) could actually take away the power of the hose. Liz Bloomfield NY
When the vacuum is in use you should not hear leaking at any other inlet or the floor inlet (VacPan) in the kitchen. Maybe you'll hear a small whistle leak but that is okay. If your system has no major leaks but your suction is weak, use this troubleshooting guide
Lost Suction at Hose
All of a sudden, I do not have suction in the hose from any of the outlets. There is suction at the power unit - just not anywhere else in the house. What could be the problem?
There are precise steps to take to find the issue. To get started, please follow our Troubleshooting Flowchart to help narrow down the cause.
Low Air Flow Overall
We have a Hoover 8100. It has decent suction at the intake on the unit but it appears there is low overall airflow as the exhaust is virtually non-existant (tried it by opening intake and disconnecting the exhaust). Have also run paper towels through the pipes and they came through fine. Any idea what to try next?
Really appreciate the information on this site. Thanks.
Nav from Calgary, Canada
Thank you for the compliment, let's see if we can help you. To get started, remove the debris intake line, turn on the vacuum manually and test the suction at that intake on the tank. If it is good at the unit, it should be good in the home unless the pipes are clogged. If air is going in well then it has to be exhausting well. Also, try removing the filter to see if suction is better overall in the home.
Low Suction After Cleaning Filter
someone else ws using the vac and said it was making a funny noise so they turned it off and took the filter off and cleaned out the debris and now the vac has barely any sucking power. The motor was replaced last year. It does not smell bad and when I put another vac where the inlet to the motor is and suck through the system that way it appears there is nothing in the pipes. I don't think there is a blockage any where. help
Usually, this indicates the unit was not reassembled correctly and is causing air to leak. It's possible that the filter may be misaligned and is blocking air flow. Another possibility is that if your system has two motors, one of them could have failed.
Low suction at all ports
I have a Fasco mastervacII (Model#852SVDM) installed in the home I purchased about 1994. I have experienced low suction at all ports and discovered only one motor is working. The motor that does not appear to be working constantly trips its' own minibreaker When turning the unit on and there is little or no air coming through the top screen on that side. Does it likely mean I need to replace both motors? The side that will run continues to operate properly, however the suction at all ports is diminished. Please advise.
You are correct, both Fasco motors both need to be replaced. The thermal breaker should be fine. When a motor goes bad it heats up or spikes thus tripping the breaker on the unit. 5% of the time the minibreaker is also damaged but you can't tell without a new motor.
Low Suction at Several Ports
Decreased suction at several ports,what can I do to improve this?. I just changed the bag.
Spray a full paper towel with any cleaner and suck it down the hose, starting at a corner. This will help clear any obstruction in the line. If only a few ports have low suction, then it is a clog in the pipes. You can view additional information on clogs on our Troubleshooting Guide.
Low Suction on Hide-A-Hose
My name is Rachel and we have a new HideAHose CV. From the beginning, I have felt the suction might be low in our main floor. Both the garage and the upstairs hoses clean easily and retract very quickly. On the main floor, I find I can suck up a cheerio, but not a sunflower seed. How much suction should I expect out of a CV? The main floor hose is longer than the other two and retracts slower as well.
There may be an obstruction in the hose and/or pipeline that is reducing airflow, or not enough power at the unit to run the long hose. Contact the installer for an inspection of the system.
Low Suction on Single Motor Central Vacuum
My electrolux with a 1590 motor that was replaced last spring isn't working right-no suction. I know there is no blockage in the pi[pes etc. but you said it may be one of two motors. I don't have 2 motors. What could be some other things I acould check.
Thanks, Ginger, Carthage
You need to systematically check the unit using our Troubleshooting Flowchart. It starts with the source and works its way back. Follow each step carefully. If indeed the suction is low directly at your one motor unit, remove the filter, check for leaks at the emptying gasket, and try it again. You will be checking the suction directly at the intake after you remove the pipe from it that leads to the home. The suction should not be low at that point because motors do not slow down after time unless they are given less voltage to run on. Let us know what you find.
Low Suction, Hot Exhaust
AV3500 Three years old. I have ordered a replacement for the cloth filer. The suction is very low and the top of the canister and the exhaust tubes are very hot. Ron - Orange, CA
To get started, remove the filter you have now and test the suction directly at the tank again. Do you notice an increase? If not, look up above the the filter for a small foam filter. If you have one remove it and do not replace it.
Multiple Motor Unit, Low Suction
I have a SilentMaster S3 that suddenly (last week)has low suction. I have emptied the bag and checked all the ports inside the house to make sure they are all closed. I tried the vacum again today (5 Days later) thinking maybe something is clogging up the pipes and now I am hearing a loud noise from the unit in the garage. The suction is still low. What could be the problem? Patti, Edmond
It sounds like one or both of the motors are bad. We suggest replacing both SilentMaster S3 motors to resolve your low suction issue.
New Inlets, Lost Suction
I recently replaced 3 of 6 inlet valves on my Sears system, model 40534 with what appears to be the exact same type (your part #651HW) and am now experiencing low suction. Is it the valves, the way I put them in or a coincidence? Natalie, Brookeville
If the new inlets were at fault, you would be hearing air leaks in the wall. If you don't, it is something else such as a clog or a bad motor. Go through the steps on our Troubleshooting Flowchart to isolate the issue and find a solution.
My Beam central vac will not suck. I tried all the outlets in the house and none of them will work. (Just a real gentle suction.) I emptied the canister and that did not help either. Help!
It is likely that there is a clog in your hose causing decreased suction. Please follow the troubleshooting tips found on our Troubleshooting Flowchart to identify the cause as well as tips on how to remedy the issue.
No Suction on Second Floor
My Pullman central vac works fine on the first floor.Nothing works on the second floor. Help Thanks, Titus
This sounds like you might have a clog in your system. Take a look at solution #3 on our Troubleshooting Flowchart for additional assistance.
No Suction On Unit With Tubes Removed
Duovac Air 10 No suction at unit with the pipes all disconnected, the motor runs fine the dust bag is clean, the catch bag is removed, how do I remove the cover(s)at the base of the motor to check the vacuum rotors to see if they are plugged?
Is the bottom of the unit properly attached to the unit? There will be no suction without the lid or bucket correctly attached to it. Is there no exhaust as well? You can look up into the motor intake. If it's clogged you'd see it and that is really rare. What it most likey may be is the filter getting too close to the motor suction hole. You'll need our Mesh #740
to solve the issue. Cut it to shape and push it up so it stays in place.
No Suction When Hose is Attached
Hi, I have a broan v20c central vacuum system. It works when hose is attached to the unit in basement but does not work at the 2 outlets that I have, no suction whatsoever. I read that the problem could be with the tubing, what does this mean, I do not know what the tubing is? If you can advise me what the tubing is and what I should do I would be very grateful.
As it could be a number of issues, please first go through this Troubleshooting Guide to isolate the problem. When we refer to "tubing" it is the PVC pipes that run from your wall valves to the vacuum unit, which can get clogged.
No Suction, No Filter?
Hi! Just happened upon your website. Thanks fpr your time! Just purchased a house with an Electrolux Central vac in situ. Motor sounds OK, but...no suction at all at the hose 'business end', yet I know for a fact the hose is not blocked (and the motor is not labouring). There is no filter material at all..pleated paper or foam. Will this unit not run without filter material in place? Don't have the model # at hand...it's at the 'new' house. Appreciate any help you may offer. Thks! Valerie
Please use our Troubleshooting Flowchart to isolate the issue. Your system should still have normal suction even without a filter. Ensure the bottom of the unit is tightly secured to prevent loss of air/suction. The filter in your system is most likely a cloth weighted filter.
Noise, Smell, Loss Of Suction
I have a Hoover central vac windtunnel for five years. It ran perfectly. Recently when it starts there is a strange loud noice, smell as if it is burning something and it reduces the suction. My understanding is that something wrong could be with the motor.Would you please tell me if it is so or something else. If it is the motor then how much does it cost?
This usually indicates a failing motor that needs replacing. You can find our Replacement Motor Options as well as cost and instructions on installation on our website.
One Valve Low Suction
I was deciding if I should upgrade or otherwise replace my current central vacuum unit. How much difference should I have in cfm at the different outlets. It seems like one of the outlets has a significant drop in flow when compared to the others. Thanks, John
It sounds like you have a clog in the inlet with noticeably lower suction than the rest. Solution #3 on our Troubleshooting Guide will provide you with information on finding and resolving this issue. If you would like to upgrade to a system with stronger suctioning power overall, we would recommend the FloMaster M85 or C650, which is most likely 50% more powerful than your current system.
Osclillating Central Vacuum Power
I have an electrolux central vacuum that is about 5 year old. Occassionally the motor won't remain steadily on. Instead it oscillates on and off every second or two and continues to osclillate: On-off-on-off ... The problem occurs intermittently and does not happen on all outlets, but when it happens, I have not found a way to solve it. I could not figure out how this fit into the your guide. Any thoughts on the cause and how to resolve it?
That is usually a circuit board issue. Does it happen when turned on at the actual vacuum tank (with a valve open for air)? If so, then it is the circuit board which can be replaced. Try our #235S Circuit Board
for the same functionality and more durability at a lower cost.
Overheating Due to Age or Air Restriction
Tom in Boston
i have a 220v 2 motor nutone 850 the suction is good but the exhaust is so hot that it warped the piping , it has dual exhaust and mufflers. the exhaust system is approx 15' it comes out and turns 90 degrees to the ceiling approx 3' turns 90 degrees rins across the ceiling 8' ,turns 90 degrees and stubs outside and turns down 45 degrees. the unit is mounted in an open basement , the top of the unit is 4-6" from the ceiling and gets hot enough to melt the pipe.... why?
Most likely the motors are getting older and running hotter. If the hot exhaust has always been an issue, it indicates the exhuast pipes should have gone straight for a few feet before turning.
Some Inlets Have Low Suction
One outlet has good suction, the other three have poor suction. The one with the good suction appears to be the one closest to the unit in the garage. I've checked the pipes in the crawlspace with the unit on and can hear no leaks. The unit is a M&S Systems Model A425 and is likely as old as the house which is 20 years. It is an electric model with a three position switch on the hose handle.
If it were an air leak in the piping system, all inlets would have the same weak suction. One or more inlets having good suction over other inlets in the home means there is a clog inside the pipe. You'll have to use the suggestions under Solution #3 on our Troubleshooting Flowchart to help locate and remove the clog.
Some Inlets Work, Others Don't At All
Our Kenmore Central Vacuum System works fine when connected at all outlets/receptacles upstairs, but will not run (at all) when connected at any of the receptacles/inlets downstairs ..? Please advise ..; Connie, Lafayette, LA
This is most likely a disconnected wire that links all the downstairs inlets to the vacuum unit. This can be very difficult to locate in a multi-level home. If you can't find it, we have the RF915 Wireless Products
that bypass the low voltage wires to activate your central vacuum unit.
Spitting Dirt From Power Brush
Myrna Karp/Florence, OR
The main carpet attachment is spitting the dirt out rather than sucking it in. However, when I place a floor attachment on the unit, it doesn't even turn on. No sound at all.
Your suction has stopped working. The sound you hear is only the spinning of the powered brush, not any air flow. Please dive into this Troubleshooting Guide to find the problem. It is easy to do and you can ask us for help at any time. Usually it is the hose handle switch assembly that has a faulty component. Suction works on one side of the switch on the hose, but only high voltage on the other side of the switch.
Stops, Starts, Stops, Starts
I just purchased a 9 year old home with a Hayden SuperVac 6000. When I attach the hose to any outlet in the home it will begin to suction then stop begin and stop. I have cleaned filter, unplugged the unit & emptied the canister. What can I do?
To get started, activate your system with the on/off switch on the unit. Does the system run for at least 10 minutes? If so, replace the circuit board with Item #235. If not, you will need to replace the Hayden SuperVac 6000 motor.
Strong Motor, Weak Hose Suction
Hi I have a fasco 851. I recently had the brushes checked and a new relay installed. The unit was given to me and I have not installed any pipes in my house yet. I have it mounted in my basement to use down there. When I turn it on I have very low suction. You can place your hand in front of the hose and it will not suck to it. I have cleaned the filter and even turned it on without the filter in but still the same result. If you take the motor off of the top of the unit and hold your hand over the small hole it seems to have plenty of suction there. I have checked around all the gaskets and can not feel any air leaks? What else can I check? Confused Aaron
It sounds like the hose is clogged. If you have good suction where you plug the hose into the wall, then you really have a clogged hose. Reverse the hose and see if you can suction it out the other way. Put your hand over the end and let pressure build and then release while shaking the hose. Repeat this process until the clog is removed.
Suction Good at Tank, Not in Home
i have a galaxie ga100 and have lost suction somehow. can you help, i believe i may have a cracked pipe, but not really sure how to find it. it has great suction at conister w/ and w/o hose. thnak you
If the suction is great at the tank with and without the hose, it indicates the system is probably just clogged. Take a look at Solution #3 on our Troubleshooting Flowchart to help locate and remove the clog.
Suction is Weak at All Inlets, No Clog in Hose
I have a beam system that is 15yrs old it has been working fine up until 6mo ago. It has poor suction at the hose,I have checked the hose for a blockage,I have none, when I turn the unit on manually I have poor suction a each inlet, I have sent a tissue through the piping to check if I have a blockage each tissue has made it to the unit. When I take the unit off the wall and check the unit for suction it seem to be good. I have a lot off dust coming for the exhaust could this be a clogged filter? It has a self cleaning filter. Thanks Mike, MN
Disconnect the pipe that connects to the intake port on your unit (debris entry point). See if the suction is good there. Remove the filter (grab it at the top side and pull directly inward). Try the suction at the unit again. Check above the cloth filter for any debris trapped under the motor. If you have a two motor system remember that one motor may go out. The center-weighted cloth bag, when removed and the suction tested, will let you know if it is the problem. Let us know what you find and also use our Troubleshooting Guide for additional information.
My vaccuum works fine when the carpet piece is attached but when I take that piece off it shuts off. Also, the low suction setting isn't working either. Otherwise, the carpet when the carpet piece is connected it works fine.
If your carpet brush is electric the suction problem may still be there, you just can't hear it over the brush. Dual motor systems can have one motor go out and will have about 50% suction loss. If the motor(s) are still good and the suction is strong right at the unit then there may be a clog in the pipeline that is reducing air flow. Follow our Troubleshooting Flowchart to narrow down the issue.
Switch Only Activates Suction To One Side
HI. My Stealth central vacuum hose switch starts suction when switched to the left and starts the brush unit but not the suction when switched to the right. Is the switch broken, or is there another issue?
Mark, Surfside Beach
Tested, Still Weak Suction, Pipes Not Clogged
hi, we have model p-125 installed in 1988. very pleased w/unit up until 6 months ago when we started having suction problems. have run balls through hoses and they make way to main canister. debris in canister is all twisted (like dna) and still has poor suction. any ideas? i've read about a filter, could that be clogged from motor side? we've reached up and raked stuff off of it. help! we have come to love the ease of just plugging a hose in and the cannister portable model just doesn't measure up. thanks.
Is the suction weak without the hose at the intake port on your unit (debris entry point)? If so, it sounds like you cleaned off the screen close the the motor and we are assuming there is no suction leaks around the gasket. If the suction is strong there and at the end of your hose from there (test separately) then you may have a break, an air leak, in the home. Also, older hoses may look fine but have lots of little leaks.
Under Powered Unit?
I have a 3 storie home, about 6,000 sq. ft. In 2000 when the home was built we installed a Airvac AV3500. I was never impressed with the suction. I was use to a Kirby. Soon after moving in the suction got worse and we just did nothing about it. Now I would like to. Does it sound like these is a problem or could our problem be the system is too small for the house? Cathy Raymond
The issue is likely due to a clog in the pipeline or clogged filter seeing as the suction got worse over time. Please read through our Troubleshooting Flowchart to help identify the true cause.
Unit Has Good Suction, Little Suction at Wall Plates
I have a 19 year old Beam central vac unit with motor 189D. The unit has excellent suction but no outlet has any suction. Plug hose into outlet, vac unit starts but virtually no suction at any of the 5 outlets. Unit seems fine with lots of suction. The self cleaning filter and canister are clean. Is it a clogged line?
It's a possibility that you may have a clog somewhere in the line. To flush out a possible clog, please complete the following procedure. Plug in your hose to the inlet nearest your central vacuum canister. Place your hand over the end of the hose for a few moments to build up pressure behind your hand, and then release your hand. Repeat this process for roughly 10 minutes. Once this is completed, repeat the process at the next inlet in your home. Continue this process until all the inlets have been completed. This should help remove any clogs that might be in your system. You can find more help on Solution #3 on our Troubleshooting Guide.
Unit Smells and Grinds
Jamie, Alliance, Ohio. I have a vacuflo model 26. Was using when it kicked out and smelled like something was burning. If I turn on it sounds like something is grinding and low suction. This is without the hose and the screen is clean.
Unit Will Not Turn On
Hi, I have absolutely no suction at all when i plug the hose into the wall outlets. Also i have no suction from the point installed underneath my kitchen cabinet.
The unit is installed in my garage, i seperated the compartment that holds the bag and found that the bag was actually almost full. My wife noticed a slight smell when she entered the garage yesterday.
When i unplug the unit from mains power socket and re-connect it i hear a click.The circuit breaker next to the power inlet (outside of the casing has not popped)There are two thin electrical wires that are also connected through the top casing a green light is iluminated when i plug in the unit at the wall socket.
Due to the fact that power is getting to the motor and i hear a click when i disconnect it, can i assume
It is likely that the motor(s) failed and needs to be replaced. You can locate the proper motor replacment by clicking on your brand here: Find Your Brand.
VacPan Toe Kick Vacuum Leaking Air
I have a 2 year old MD SilentMaster. When vacuum is on at any outlet, there is a very loud air noise at the pantry vac pan. The outlet close to the vac pan has little suction whereas the suction is fine everywhere else in the house. the pantry vac pan and adjacent outlet are the farthest away from the the unit. Cracked pipe?
The VacPan door is not closing properly, which allows air to escape through the front opening. VacPan Repair Kits are available on our website.
Vacuflo 26 Clogged Screen, Low Suction
My family just purchased a house with a very old Vacuflo model 26 installed. The system has low sucking power and after reading here, I've found that the screen in the cone is truly clogged. Is there a way to take the screen out so I can unclog it? I scrapped the debris off the side that faces the bottom of the cone, but how do I clean the other side?
Remove the motor chamber on top of the unit and then remove the motor to get to the upper side of the screen.
Vacuflo Low Suction
Daughter has vacuflo model 107 came with the house. Had this trouble before, no suction. cleaned out cleaning people filled up. checked circut breaker reset button does not go in it just wiggles. What can I do next. Janet Boca raton Fl
The most common issue with Vacuflo is the screen just under the motor. It is the only "filter" on a true cyclonic Vacuflo vacuum and must be cleaned off often. Reach up into the unit after removing the bottom bucket to scrape it off.
VacuMaid with Low Suction
I have a Vacumaid P125 central system.The system has extremely low suction on the vacuum hose. The hose has no blockages. The motor is running hot. It is about 20 years old. What other information do you need to diagnose the problem?
How is the suction where the plastic pipe from the home connects to the Vacumaid? If low, have you cleaned the screen below the motor, up in the cavity of the machine? It gets clogged with hair and carpet fibers, restricting airflow.
Why do I get a lower waterlift reading on the unit by itself, not connected to anything, then the water lift number of the specs for the unit?
Correctly you disconnected all pipes and tested the unit by itself. There are three factors that could provide a lower waterlift:
- Lower electricity rating. Motors are 120 volt (or 240) and may be receiving lower voltage in this location. This represents a motor performance drop depending on the actual voltage. Also, a remote location far from a transformer will have different electrical voltage than one right next to a transformer.
- Elevation. If the installation is at a 2500’ then you would have thinner air and a calculation loss of 10% in waterlift compared to the standard rating taken at sea level. An elevation of 4,000 ft would produce a 16% drop in waterlift.
- Ametek states their motors have a ±10% variance in performance. You may be experiencing one particular portion of this curve.
We have a Fasco central vac system that at times seems to be working ok, but at other times the suction is very low. We've made sure the hoses are all clear, the filter is clean, both motors seem to be running normally. Do you have any suggestions on what we can do? Could it be time to replace the motors even though it seems like they are running ok? We believe the unit was placed in the house in 1988 and it is model #852SVDM.
Thank you--Larry and Angela Watts
Some Fasco's had one small motor such as the 851DM, A853 and A853449. If you have a model with two minibreakers (two motors) then one motor can be out. If you have a powerful single motor unit then you have some sort of clog or air leak.
