Question about Vacuums

Nutone model cv-350 vacuum motor will not shut off. I have to unplug system in garage. I disconnected wire to house vacuum inlets and motor is still running. There must be a reset on the motor. I have turned the external switch on and off and still no help.

    I have the same problem. I have a nutone cv353 that won't shut off. I disconnected all of the wall units in the house, turned the switch at the unit on and off and also disconnected the main wires going into the unit that supply the power to all of the receptacles in the house and it still kept running. I had to unplug it to get it to stop. Does anyone have a solution to this problem?

Mine is the same, and it is the relay welding itself closed. The relay is switched by the low-voltage wiring that connects to the vacuum outlets, and it switches the motor on and off. Mine was welded in the energized position. I have cleaned and filed the contacts on the relay, and that solved the problem for about a week. I suspect the relay contacts were plated, or a worn motor is drawing a little too much current (it is several decades old at this point).

Central vac not sucking


Check for a plugged tube in the wall by listening to the motor when it's running. If it sounds like it's running too fast then there's an obstruction. If it sounds ok, then there's a disconnected tube somewhere in the system.

Nutone Scovill 350 will only turn off if unplugged


Some units have an on/off switch on the power unit itself. Check to make sure that is not turned on. Unplug your power unit and remove the 2 low voltage wires (not the power cord itself) . The low voltage wires start at the unit and run throught your home and attach to each hose inlet. They are usually attached to the unit by simple wire terminals or wire capped to small wires coming out. Just unlug the terminals or unscrew the wire caps and pull the connections apart. Plug your machine back in. If it still comes on the problem is the relay or circuit board/switch/ relay assembly inside the unit. If it doesn't come on with the low voltage wires unattached then you may have two wires touching somewhere in the low voltage wiring.

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.

I have a Nutone central vacuum model number CV450W that was working great until I recently removed the hose and it now runs continuously until I pull the plug....any suggestions please


Disconnect the thin low voltage wiring between the vac and the rest of the house. If the vac continues to run you have a defective relay in the vac motor housing.
If the vac stops you have a short in the wiring in the house, likely behind an inlet in the wall.
If any inlets have been disturbed for painting or renos lately that would be the first spot to look in the house for a problem. Look for wires behind the inlet valve which are touching against each other or a mounting screw or against a metal mounting plate behind the inlet. Start at the last inlet used. Be careful not to loose the spring under the screws where the wiring attaches to the inlets

Nutone CV556 Vaccuum Cleaner -Continuously running


Start with this. Unplug the vac to shut off, then disconnect the low voltage wiring at the vac.Plug the vac back in. If the vac still runs you have an internal short on the relay or wiring inside the vac.
If the vac stops then the vac and final wiring is OK and the problem is in the wiring in the house.
Have you removed any inlets for painting or had any renos done or pictures hung. If so undo what you did last. If inlets were disturbed remove them and look for low voltage vac wires touching metal backing plates in the wall or touching the inlet mounting screws.
If you have done a reno or hung pictures you may have pierece the wire for the vac creating a low voltage short which will keep the vac running until removed. I have seen this happen with freshly installed 1/4 round molding along a baseboard

NuTone Central vac won't turn off


If the central vacuum tank will not turn OFF even with the switch in the “OFF” position, then the low-voltage wires should be disconnected from the tank. If the tank continues to run and still will not turn off, then most likely the relay inside is defective (but it could be a defective and/or shorted ON/OFF switch). If with the low-voltage wires disconnected the tank is able to then be turned off with the switch, then there is a short in the low-voltage wires or a hose is plugged into an inlet somewhere. ~ TTURAMBAR

If the top comes off, it will be by the motor and exhaust. Just replace it with the new one, make sure you don't mix up any wires. Also unplug it from the AC first.

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.
