Questions & Answers

Lint Getting Through Filter?

fasco 852svdm vac. i noticed that the suction had decreased. i investigated and found dust and lint on the screen under the motor unit suction side. i cleaned it and the suction returned to normal. after a few hors of use the suction decreased again. i found the same problem. i took the cloth bag out and cleaned the rubber and the slot it snaps into on the housing. i do not see any holes or damage to the cloth bag. it is beyond me how dust and lint can be getting thru. any suggustions? Mike Nashville, NC

Our suggestion would be to replace the cloth filter but they are not really available any longer. We see that after years and years of use junk can get through it. Please read about the replacement on this page If it is not going to work we suggest a new central vacuum unit.

Gasket Replacement in Fasco Tank

I have a fasco 851 central vacuum that does not have proper suction. The top housing gasket (motor section) is damaged. Is a new gasket available? John fuquqy-Varina, N. C.

Gaskets are no longer available for Fasco as the company has been out of business for quite a while. Hopefully you can figure something out using material from other places. Maybe use weather stripping?

Fasco Replacement Electric Hose Options

I have a FASCO MODEL A853 SER B. The unit is 15 yrs. old. Replaced the vacuum motor about 6 mths. ago. Has given great service, but now need a new hose. The old hose has a two pronge at the handle for a carpet cleaner attachment with and electrical cord that must be plugged into and electrical outlet. Have looked but can not locate the a replacement. Can you help. Thanks, Ralph Connelly Springs, N.C.

Please verify that your inlet valves measure 1.5" ID (inner diameter) and has two, round metal contact points inside of the opening. If so, you can view compatible hose options here:,353GC.

Manual, Old Style Wand and Attachments

Fasco Model #851. I ordered a new hose and motor for my Dad's Fasco Central Vacuum System. His house was built in 1982. He received the hose and motor a couple days ago, and the attachments are totally different than the original ones. There was no owners manual in the box. We're trying to figure out what plugs into what. Is it possible to get an owners manual, or download one?

Manuals are no longer available but the solution will be easy - however cost some money. The way the old hose and attachments worked is no longer valid. You'll have to purchase new wands and accessories that work with the new hose. Let us know how we can help you work that out.

Cloth Filter Issues

I have a Fasco Built In Vacuum Cleaning System Model 851 from Fasco Industries. My cloth inverted filter with the built in weight does not stay in place. I have to constantly put it back in place after cleaning the screen at the motor to get my suction back. I looked for a replacement, the bag seems to be about 14" but may be 1/2 to 1" bigger, I'm not sure. So you have any replacement or ideas for me? Kathy from Agawam

Please read the detailed note in the chart regarding the filter The length of the filter doesn't matter, only the width.

Metal Inlet Needed, Parts?

I have a model S852SVDM whole house vacuum that was installed over 20 years ago. At that time the name on the unit was a Spartan Built In Vacuum System. I understand that Spartan is no longer in business but that the Fasco unit is interchangable. I am in need of a part from the central vacuum inlet oval (Bronze). I need the two electric eyelets that make contact with the vacuum hose. Are these parts available alone? If so, I would need the part number to order and the cost. Thank you Jim Niles, MI

The valve you need is still available and compatible but the parts that make up these valves are not sold separately to us so we can't sell parts that way either. Take a look at the metal inlets offered here

Fasco Brush Parts

I need new rotating brushes for the Fasco power head. Model 860EB, part # 52988-2 bristle set Ron

I'm sorry, we don't carry replacement parts for the Fasco power brushes. You can replace the carpet head with a new one. Take a look at your options here,

Fasco Will Not Turn On

Fasco Master Vac II 1986 does not turn on, just a loud click from what looks to be a relay. Dual motor/dual mini breakers. Do I need a Vacuum Motor Circuit Board Dual Motor 28 amp 120v Part#235L or the 15 amp one? or maybe just the relay?

You may want to check the motors first to be sure where the problem lies. Connect each motor directly to a power source and see if they turn on without the relay first. If they do, then you can replace the relay. If not, then the motors need to be replaced.

Relay Needed

I have a Frsco Vacuum Model A853 S/N 101391. I need a relay. It is an 18V coil and rated 250v 18A. Any help finding one will be appreciated. William Matthews, Williamsburg Virginia

Those parts are not available any longer but an electrician can easily replace them all with a single central vacuum circuit board. We have them for single and dual motors. Print the large photo to use as the wiring guide and attach it to the tank through the mini-breaker holes that are there or that you need to create.

Intermittent Motor

I have a Fasco 851. The unit sometimes will not turn off. Sometimes if I flick the manual switch a couple of times it will turn off, sometimes not. The hose switch also works intermittently. I suspect the relay but I would like some guidance on a replacement. It is an 18amp "Essex RBM 8317". From your parts list it looks like I will need a new transformer too. Can you help?


Yes, the relay is going bad. We suggest an easier and less expensive fix than replacing a relay and transformer. A new circuit board made for the central vacuum is better as it replaces the minibreakers too. You can view/purchase the compatible circuit board on our website. Your electrician can use the large photo of it as a wiring guide and do the job in less than an hour. The unit is attached to the vacuum with the minibreaker screwing on from the outside.

Fasco 851DM Motor Gaskets

I have a Fasco 851DM which was installed in my home when it was built in 1988. Are rubber gaskets for the motor available anywhere? I have had an electrician check the motor and he thinks a new gasket might solve my problem of little/no suction. Cindy, Harrisburg, PA

Motor gaskets can be found on our site here,,220 . We carry gaskets for both of the two standard motor sizes, just select the one you need.

Parts for Fasco Patton Main Unit?

Kevin, My mom has a Patton(which replaced her Fasco) and she needs the rubber o-ring/grommet for canister which pipe slides through into canister in order to make a tight seal for the pipe from wall inlet(the bonus inlet on the left side of canister) at bottom, in order to seal the unit tight. i cannot find this part anywhere. thanks

Parts for this vacuum are not really available any longer. Hopefully you'll be able to use something else to fill in the gap. Also, down the road you can easily replace the entire unit with a new one. You are looking at a stronger unit for about $500.

Motor Plate Removal

I have a Fasco 851DM with a burnt out motor. Motors are located in top unit. I'd like to buy replacement motors, but can't figure out how to remove the old motors. There is a metal plate with holes for motors and the wider part of the motor and fan assembly is below the plate. The holes are narrower than that bottom portion and only top of motor sticks up from hole. Can't find a service manual for Fasco and can't figure out how to remove plate or access motors.

We have a lot of Fasco customers that replace the motors, but we have not been asked this question. That plate does need to be removed in order to reach the entire motor and most likely the fasteners. Please send us some photos and we'll be able to assist you better. Hopefully someone else will read this post and give us all an answer.

Black Foam Filters

Looking for replacement for 2 black foam filters we found from under the top of our 852SVDM unit. Did not know we had to do anything with them; one fell apart, and the other one is trying to fall apart. Do you carry those?

Those filters are not really needed. They filter the intake air for the motor cooling fans. A screen or breathable foam from any source can be used instead if you so desire, though. Thanks for writing in.

Still Low Suction Power

We have a Fasco Master Vac 11, we have diminshing suction. I took hose 36'and pushed garden hose to the head and there was nothing clogging the hose. The motor comes on and sounds OK, I cleaned the bag and still nothing. The unit is 17 years old, your suggestions? Dave Stephens, Florence,SC

One of the motors is probably bad, yet still spinning. Remove the top of the vacuum and look closely as you start it up. One motor will not start spinning right away, that is your bad motor. Use the Fasco motor page online to get the correct motor and instructions.

Relay Needed for 852SVDM

Neal;Annanale,Mn. 852SVDM Mastervac 11 Unable to locate a relay for it.Would like to know of a replacement. #129990-1480 W-R/RBM 9230 1HP@125V-2HP@250V 250V 18A coil 16V 50/60HZ

The electrical parts are not availabe for this brand, as far as we know. However an electrician can easily replace all the electrical components with a simple two motor central vacuum circuit board here Print the large version of it as a guide. Mount it to the inside side of the unit by making three holes (two for mini breakers, one for low voltage tower).

Fasco 862EB Parts

I have afasco model 862EB, this no. is on the bottom of the power head (carpet broom) Can you supply a replacment belt for this powerhead .and are there any other parts available plus a parts breakdown diagram available for this unit Stan form Palmyra

Stan, Fasco has long been out of the business and customers may be able to match up belts in the market. We list every detail of our belts for this purpose. Sorry we don't have a cross reference.

Fasco 862EB Parts

Re: Fasco model 862EB central vac power brush.. Where can I buy a replacement brush with bearings?

Sorry, those parts are no longer available. You can replace the entire brush but we'd have to work with you on the compatibility of the hose. Would you please call us so we can walk you through this and present your options? Worst case, sort of speak, would be to replace what you have with a new hose and tool kit. The electric kits we sell all fit into Fasco systems as they are.

Canister Gasket

where can I get a dirt canister gasket for a fasco master vac 852svdm phil in salem nh

Hi Phil, Fasco doesn't provide them, they are out of business. If you can't make one up out of weather striping from a hardware store, lets talk about replacing the entire unit at some point.

852SVDM Take Two Replacement Motors?

we have a mastervac II model 852svdm it has 2 motors. Is the model you show in place of both of them or do you have to order 2

Hi, yes it takes two replacement motors. We are about to stock the original motor and suggest you check back with us for it in 2 weeks. Otherwise you can use these motors, they are newer, more efficient and they cost less. But they do have about 8% less power.

Fasco 851 Vacuum Motor Replacement

I have a Fasco Central Vac System, model #851. It uses a 120v, 13A motor which I seems to have burned out. Can I get a replacement motor for the system.? The motor has 1083 written on it, so am assuming that its the orignal. Maury, Charlotte, NC

Hi Maury, we have the motor listed here. It is an easy replacement.

Dirt Blowing Out the Top

Hi, we have a fasco 852SV brand unit. We replaced the motor a few months back - purchased from this site. Now we have a problem with dirt blowing out from the top of the unit. Do you know why this would be? There is a black, rubbery, round piece that has fallen apart... It looks as if it was a seal. Can this be replaced? Is this the problem?

Hi, dirt is getting around the center-weighted filter cloth which was sewn into a black gasket all the way around it. We have a bag that nearly fits. Please read the information on the far right column of the chart here:
