SOURCE: nutone cv353 central vac blew up

My guess would be that the motor is done. Impossible to diagnose for sure without seeing it of course. If you were happy with the unit before the trouble, a replacement motor will probably run $250-$300. If you are interested in a new unit, shop around. There are definitely better designed and more powerful units out there, although some of them can cost quite a bit more than $300. Good Luck!!

SOURCE: 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

SOURCE: 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.

I have a 4 yr old vx6000c central vac that constantly blows house breaker


This unit requires a 15AMP 120 VOLT dedicated circuit. If there are other appliances or items on this central vacuum circuit, this could overload the circuit causing it to pop. The other issue that could be occurring is that the central vacuum is on a GFI circuit or ARC fault circuit. Central Vacuum Units are not designed to run on these types of electrical circuits.

Nutone cv750 problem


I doubt that's an electrical breaker - because it wouldn't take 10 minutes to flip, it would happen almost immediately. It must be the heat breaker. There are two reasons your vacuum system could be overheating and tripping that breaker. Either you need to replace the filter - if it's partially clogged then the motor may have to work too hard to get suction and cause it to overheat. I'd suggest checking the filter first, because that's the easy fix. If it's not the filter, then your motor is going out. You'll want to replace that. Check the filter, and let me know. I'll see if I can find a place to order a new motor for it.

Nutone cv353 unable to stop


You may have a stuck relay or one of your access port switches may be bad. According to the owners manual: "A complete check of all Wall Inlet and Power Unit low voltage control lead connections (external yellow leads). Turn system off by removing fuse or tripping circuit breaker at
house fuse box."

Motor does not run. unit has power. circuit breaker has been reset. unit only "clicks" when vacuum hose unit is plugged in. possible brush problem ?


I have an old model 350 X. It does't run. It seems to be a problem with the coal brushes.
When I connect the 16 V points ,the relais clicks.
Once I sprayed the brushes with silicon oil, it runs a moment.

Central vac will not turn off


You have a defective internal relay on the vac. Check for warranty coverage as this is a common occurrence on these big box store units.
If beyond warranty the relay should be a straight forward unit, miniature circuit board type plug in device. Find a Broan Nutone service center or take to vac pro shop for parts.

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.
