Having problems with your Broan-NuTone CV353 Central Vacuum ?

Nutone CV353 does not shut off, think it is the relay board

\015 I have a Nutone central vac model CD353 and the unit does not shut off, I have disconnected the yellow wiring for the outlets it still runs and then the switch on the unit and it still runs so I am thinking that the relay is not shutting off the unit. So I am trying to see if I could buy the relay because it looks easy to change (just disconnecting and connecting the wires). Does that sound like the problem or could it be something else I should test. So looking for some advice\015

Answers :

You probably have a stuck relay. You \015\012can try tapping with medium force next to where the low voltage wires \015\012are attached to the unit using the handle end of a hammer. Even if this \015\012works it's time to replace the circuit board. Take the unit to a local vacuum repair center for service.

I need a relay board for a Nutone CV 450 12.6 amp dual motor vacumn unit. Where can I locate one? Part #??? Unit will run by itself, then shut off. Unit wll not run at all. It has a mind of its own.

I have a Eureka Central Vac CV1601b. The motor does not stop unless the Unit is unplug from the electrical outlet. Any Idea?.I removed the control unit to check if there was disconnected wires or burnt wires. Everything look normal. The circuit board does not show area that overheated. There seem to be 2 relays. Likely one of the two went bad. What do you think.

Model # 5770 the brush motor runs and shuts down after a few seconds...Turn unit off and the brush again will run for a second or two...If I don't turn unit off brush will not start up..Could it be the printed board..the motor brushes..or the wiring that goes from the printed board to the main motor...Thank you


Seems like your unit goes into failsafe because it detects something wrong. Well you should check the brushes and replace them if they are worn out. Also check the wiring for shorts etc, becaue the unit maybe tripping due to an overload. The printed ... Bissell Vacuums

I am looking for a contol board for a miele s143 stick vacuum. The vacuum wont start but when I supply power directly to the motor it spins. I think the switches are OK so I have concluded it is the control board Thanks Don Kenney

My Shop Vac (Brand) Mdl#934-16-11 keeps shutting off while I'm dry vacuuming. I can turn it back on then it will shut off again. The filter is spotless, so that's not the issue. There isn't any reset buttons. The only thing I can think of is that the float for wet vacuuming is somehow being sucked up causing the the motor to be tripped off. The vacuum is only about a year and a half old and used only sparingly. Help!
