    This solution was very helpful to check out what was wrong. We discovered the switch inside and replaced it for $43. We had been told by a company that we would have to replace the whole thing for $600. So this was considerable savings. thanks

The first thing I would do is to disconnect the low voltage wires from the unit. Does the unit continue to run? If so, it's probably an internal relay sticking in the unit. You can fix this yourself is you are handy, but I suggest calling your local dealer if you have any doubt. If the unit doesn't continue running, than you most likely have a short in low voltage wiring in your house. Check your inlet valves first by removing the screws and looking behind the faceplates. If you have inlets that are powered with 110v for you power nozzle (Supervalves, or Electravalves), be very careful as you could be exposed to 110vac. Check your vacpans too, if you have any. The wires should not be touching anywhere. If the two wires touch, the machine should come on. Good Luck!!

My vacuum is constantly shutting itself off. When


It sounds like you have a blockage somewhere and the air is not passing over the motor to keep it cool. There is usually a thermostat mounted either on or near the motor. The blockage can be anywhere from the elbow ( the swivel part of your carpet sweeper if you have a canister vac) up thru the hose.If you have a canister vac, use a broom handle to push through the hose to clear the blockage. DO NOT ! use a coat hanger or anything that will cut or tare the hose. There are electrical wires in it that have 120 volts and causes quite a shock !
.
If you have an upright vac, start with the duct hose that comes from the part with the brush up to the hose and on to the main canister of the vac
If this does not work, take your vac to a reputable vac shop for repair. Hope this helps,
Joe

Switches will not turn off unit. model #cv450w


If the switches on the hose will not turn off the vac you have a short in the wiring of the vac pipe system or a defective relay on the circuit board. Plug the vac in again without the hose and disconnect the thin low voltage wiring were it plugs into or screws onto the vac.
If the vac continues to run once disconnected from the low voltage circuit you have a defective relay in the vac itself. Some are circuit board mounted , others freestanding. To avoid a service call you can take the tank off the wall and take it to a pro shop or remove the top hosing if you are confident and check out the relay for a replacement part.
If the vac stops your issue is in the house. Has any painting been done or any inlets removed lately.. check that area first for a short at the inlet. Go back to any and all inlets and remove them one at a time checking the mounting screws and backing plates for loose wiring which is touching either the metal inner wall plate in the wall or a common screw . Test the vac as you go.
If this does not help, you will need to examine the wiring in the house , running along the pipe. Again if anything has been disturbed recently, near the vac, or near any piping that would be your first suspect area.
Post back to advise.

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

Hayden 6000+ wont run


Define hose works or doesn't, no suction, hose will not activate vac , etc.
Test the vac by shorting across the low voltage terminals where they enter the machine. If the vac works here your problem is in the internal wiring, at the valve or the hose to wall connection. If the vac will not run, you will need to check the motor for continuity across the motor leads.

Central Vac does not shut off


Sounds like the relay that is in the central vac unit is stuck to the ON position. When you plug it back in..does it start right up ? If so.. You should be able to disconnect all the receptacle feeds to the central vac unit at the central vac unit to determine which one ( if any) is calling for the vac to stay on.. if none are.. then it is internal to the vac and may be a stuck relay... Hope that gives you some ideas to check...
