Your relay is bad. This is very easy to change out yourself. There are several websites that sell this part online. Some websites offer free tech support.

My central vac unit does not turn off even when hose is disconnected. I have to unplug the motor unit in the garage to shut it off. What do you think the problem is? It is a 7 year old Electrolux


Possibly the power module. Or a short in the wiring. Take it to the local Aerus Electrolux store and have it checked by a service tech to be sure. The pm is a lot less expensive to replace than a whole cv.

I have to go into the garage to turn on the motor on the tank and to shut it off. When I plug the hoses into the outlets in the house, it doesn't turn on the tank motor. I don't know what part to get and...


Is this Electrolux that's now known as Aerus? If so, take it in to the Aerus Electrolux store for a tech to look at. You can find the nearest Aerus Electrolux store by following the instructions on the site at bottom of page.

It sounds like a problem with the power module in the vacuum. Without checking for myself, that's my best guess.

Have you checked the hose for clogs or leaks. Clogged and leaky hoses are an area of concern with any central vac. Unless you hose has a hose sock, then wear and tear from constant rubbing on floors and other surfaces will result in holes and cracks. Pulling the hose can also result in leaks where the hose attaches to the handle and intake connector.
Mix some dish soap with water.
Use shop vac to blow air through hose, with other end capped or "clogged".
Apply soap solution to each end of hose.
If bubbles form, this indicates leakage. Hose will need to be replaced.

A Nutone CV-450 System with inlet nozzle switch issues


You are suffering a connection problem of the hose end fitting to the wall outlet. Either the hose is not aligned with the two pins in the wall outlet, or the pins in the outlet are dirty and not making good connection to the hose end fittting.

Central vacuum with new motor shuts off and throws switch


Your mini breaker is probably bad if its a new motor. Its found on the relay board and they can weaken over time, especially if you had a bad motor before that tripped it a lot.

AirVac ZX6000 won't turn off!


There is a relay board inside your unit which is most likely bad. If you have the make and model, you can contact me and I can order the board for you(pending your mechanical abilities). If not, contact your local central vacuum installation company. www.thevacdudes.com

I have a central vacuum system. When I disconnect the hose from a wall outlet the central canister does not shut down dispite my turning off the vacuum at the handle of the hose. The only way I can get...


What I'm hearing is the canister(Not the Powerhead) portion of the unit is running all the time unless you unplug it. this problem could be caused by a short in one of your low voltage lines running through the house. To determine that just unplug one/both low voltage lines from the canister, and plug it back into the recepticle. If it doesn't start up then you figured out that it is in the house somewhere and not the unit. If it is in the house I would check for water in the valves, or you're just gonna have to chase down the short. If the unit is still running with the low voltage wires disconnected then it is probably the relay on the board, which means you will need a new board unless you're expereinced at soldering and want give it a try replacing just the relay. Which you'll probably need a new board by the time you're done anyhow. LOL

Good Luck

Central vac


It is possible that the low voltage wiring that controls your central vacuum has been damaged during the cable work. You can check to see if the low voltage relay is working by shorting the two terminals together at the unit. Just disconnect the two small (18-22 gauge) wires from the unit and short across the terminals where the wires connect. If the unit comes on, the vacuum is fine, and it is most likely the low voltage control wires that have been damaged. It should be a pretty easy fix, if you can get to where the wires are located. They are probably just pulled apart at a joint. Good Luck!!

I have a 3 year old NuTone CV 353W central vac system and recently the switch on the hose handle does not turn the system on from any outlet in the house. I have to plug the hose into the outlet and then turn the unit on from the switch on the canister. Any help would be greatly appreciated. Thanks

Hello,
I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure. There are a couple of things that come to mind, 1st. you may have a bad switch in the hose and in most cases that can be repaired – if not you would have to purchase a new vacuum hose. 2nd. You may have a bad inlet valve in your hose and most of them are low volt of which would only cost less than $10.00 and can be replaced yourself unless you have what they call a SuperValve of which has 2 low volt wires and then it is wired to your home electricity and that should be replaced by an licensed electrician. It is a low volt and high volt inlet.

#3. the last thing you may check id that you may have a bad relay in the canister itself. Because you should be able to turn on the Central Vac with the switch on the hose and everything should work just fine . feel free to contact your local vacuum cleaner dealer in your area of call the Nutone Factory cust serv line for further assistance. So if you need further assistance, please feel free to contact your local vacuum cleaner dealer in your area or in the yellow pages, or contact the factory phone number or website to further assist you with your questions.
