Having problems with your Broan-NuTone VX475 Bagged Central System Vacuum ?

My central vac wouldn't shut off when I took the hose out of the wall socket, I have to plug and unplug the unit at the electrical outlet.


Answers :

The start stop command is done by a small switch that is located in the wall socket - this command is then transmitted thru some wires at the relay on the control board of the unit, activating it and powering the machine.
So you must check 3 things:
1. the switches on the sockets and 2. the wires connecting them to the main unit's control board - if you have more than a single socket then it's definitely not it: they can't all fail at the same time. To test them just plug the hose, disconnect the wires from the control board and test the continuity with a simple multimeter.
3. the control board (more precisely its relay) - it gets stuck. If the relay (or even the board itself) is defective you will have to replace it - it can't be fixed. The only ones that have it are the manufacturers - you will have to contact them for it at

Since testing and replacing involves working with live power you should do it only if you know how to do it safely. If not, call a repairman.
Do you have more than one socket?

Hooked everything up per directions. I plugged it in to the closest electrical outlet and nothing happened. The lights did not light up, the connected wall control and sensors leds do not light up. It appears the unit doesn't have power. The electrical outlet socket is fine as everything else I plug into it works fine. I have tried every other electrical outlet available. The unit won't power on from any outlet, and all of those outlets run other things, like power tools an refrigerators

Electrolux Centralux I have a Electrolux Centralux. When I plug the hose in at one of the wall outlets the motor will not start. If I go to the motor and slap the unit it will start.....then...it will not stop unless I unplug the power cord to the motor. If I plug the power cord back in, the unit will not restart until I slap the motor unit again. The unit has only been used 20 - 30 times. Any suggestions?? Thanks, Bruce

Dyson DC23 Vacuum shut off and came on. Thought it was a problem at the electrical outlet as when moving plug it would come on again.

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.

Just purchased the unit 2 weeks ago. Worked great. Last night I left it plugged into an outlet - but turned "off".

We have an Aquanot II charger for our backup sump pump. We unplugged the charger from the battery, and just plug the charger into an outlet. As soon as we plug it into an outlet, the two LEDs lite up, and then the fuse trips within a second. We bought the whole sump pump backup system in June 2009, so it is fairly new. Any idea whether the charger can be repaired?

Hoover S3765 I have a Hoover S3765 (serial # 040600024465) and the unit stops working for no apparent reason. The light on top of the unit goes off when it shuts down, so I don't believe it's a problem between the hose, the tube and the floor unit. Sometimes I have to let it sit for over one hour before it will come back on. I've tried different electrical plugs too. Still won't turn on. Any ideas or suggestions? Thanks
