AirVac Vacuum Unit Services Q&A

We have the AV2500 Airvac central vac system. The low voltage wire is still connected/plugged/snapped into the unit at the top. However, the bare wire ends don't go anywhere and look like they were pulled out and are live (we shut the breaker off). We discovered this when we could not get our in house system to turn on but the unit works when turned on manually with the on/off switch (breaker on). Where are these wires supposed to go? Thank you.

I have a FX3000 home vac system. I have already replaced the motor, but it continually trips the microswitch breaker when we use it. Should I replace the breaker, as it may have become weak or is something else possible more likely to be the problem? Joe from Huntsville AL.

I have an AV625 with the weighted cloth filter. The filter will not stay in place long despite my many efforts to clean and re-insert it. Can you advise if there is a trick to this, it seems pretty straight forward.

just moved in to place with air vac. when hose is plugged in to outlet red led light comes on saying that further operation could damage motor . what could be problem. tim. thanks

Jody - Marion IA - 6 mos ago we moved into our house that has a AirVac Platinum Series Central Vacuum System. I was using the carpet attachment when there started being a burning smell, it also smells that way in the garage where the unit is located. What caused that? We are trying to clean out the carpet head and take it apart, but there is no easy way to do that and the only instruction manual we have show how to install the unit. Any suggestions?

I have a Nortek model FX100. The fuse ( 15A 32V 311 ) is blown where can I get a replacement Walter East Meadow NY

I have an M&S Systems Air Vac Model # AV425A. The problem is the motor runs continuously when the unit is plugged in. I can turn it on and off with the rocker switch. The motor continues to run when the hose is plugged into the wall unit and when turning the unit to off at the hose handle. Is this a relay problem. The unit has a separate transformer and relay. Can I get parts for this unit? Thanks! Lance

Don in Sanibel, FL. AV3500 installed a few years ago, not many hours on it. Stopped working. How do I REMOVE the brushes to replace them? (purchased brushes a couple of days ago, can't get the existing ones out). Thanks

Hello: Our house came with an AirVac AV550 (or 220, hard to read the label); i recently purchased an AirVac Deluxe kit from you guys to use with the CV. Now I am thinking of replacing this old unit because (1) it is noisy, (2) there seems to be no exhaust tube, so the fine dust is probably being vented into the garage, and (3) i am not sure if this CV is powereful enough. Qustions I have is, (1) do i have to buy an AirVac replacement because I already purchased the AirVac Delux attachment kit, (2) what is the corresponding AirVac new model to replace my old AV550, (3) i am reading multiple reviews about type of CVs, tornado, bag, bagless, etc., what in your opinion is the best option (I can add a vent to funnel the dust outside the garage if needed). Thx

I lost my remote fob (transmitter) for my airvac wireless (model VMRC2). Is there any place I can buy a replacement remote fob? Thx N, San Jose, CA

I have an AirVac 425A and I'm trying to locate a wiring diagram (Separate relay and transformer). Can you provide / help me to find? Thanks you. Chris, NJ

hi there, we bought an existing house with the red airvac series probably the vr3000, or w.e. the person before us had dogs and everytime we run the vaccum we better have the garage door open because it stinks, we dump the bucket atleast once a month-6weeks and im wondering if theres any way to clean that top filter or w.e it might be. my husband is tempted to just stick a hose up there to push everything down haha. please help. ali in jacksonvile

I have an Airvac AVR 7500 central vacuum system. If I turn the unit switch on, it runs all the time with or without plugging in the hose. If I turn switch to off position, the unit runs only if I plug hose into the wall connection. Is this related to the low suction. Thanks. Yu

AirVac AV625 My AV625 is approx. 18 yrs old. It appears the motors need to be replaced. We have been happy with performance but the vacuum has always been uncomfortably loud. (located in the garage) Assuming it will cost approx. $400 to replace two motors and filter would I be better off buying a new, hopefully a much quieter unit. I have seen mufflers for vac units. Can I put one on this vac? Also, it is not exhausted outside. Should it be? Thank you, Phil Rock Hill, SC

The reset buttons on my airvac 525a will not go in. The unit has no power at all. Outlet works just fine. I reset the breaker anyway. A water line had a pinhole leak and water sprayed down over the unit. I unplugged it and let it dry out for 6 days before trying to start it. Nothing happened at all. The reset buttons just won't go in. The unit is 18 years old. Is there a fuse inside the unit? How do I determine if I need to put in a new motor, or should I just get a new unit at this point?

I have an AirVac AV3500. The unit will run fine, but will not stop running unless I flip the breaker. Any suggestions?

Hi I have moved into a house with a gold airvac 3500 system. Manual says use disposable paper bags over filter but ours looks different to diagram in manual? Also suction is terrible. I've removed filter bag & washed it, what else can I do please? Jan, Rochester, NY

Hi, I bought a house which has an M&S Filtex FX 3000 model central vac. installed. The low voltage wires are not connected to the unit and I can't figure out where to connect them. The wire strands are crimped into the slip-on connectors and I do not know where to connect these. Any help is greatly apprecited. Thanks. Boby, Germantown, MD

Have a airvac central vacuum system. System put in 21 yrs. ago. Vac. would not turn on, thought it was the motor, put new motor in and still did not come on. I overrode the relay and motor turn on. So I am looking for a Potter & Brumfield relay, #s87r1a2b1d1-24 volt. Any help would be appreciated. Thanks, Bob

I have an AirVac 410 system with a Lamb 116207 motor. After a recent power outage the relay maybe the transformer are not working. I have tested the motor and it works great. Is there a new board with a relay and transformer on it I can replace my old one with or should I just replace the transformer and relay separately? If separately what parts should I use?

I have a gold series AirVac 6 years old that runs then cuts off for a few seconds, back on, off again. Never more than a few seconds. May run for a extended amount of time without shutting off. Never shuts off when connected directly in garage. Thinking maybe problem with wiring in hose. Thank you, Tom in Aiken, SC

i have av5500- does not have power, and can't find reset swich

AirVac AVR24000 runs for couple of minutes then reset switch kicks out. My AirVac is about 2 years old, but only installed for 1 year, and only been used for 6 months. All of the sudden it will only run for a minute to 5 minutes then the reset trips. I have cleaned the filter bag and even the Hepa filter over the motor (do I need this? it is very hokey)?

I have an Air Vac 850B, 19 years old that does not run. The local dealer said one fuse was blown but when replaced the unit still did not run. M & S no longer has parts for this model. Do you know where I could get parts? If parts are not available what would be the easiest fix for my 4000 ft2 three level house?
