Having problems with your Broan-NuTone CV350 Central Vacuum ?

Central vac won't turn off unless we unplug - Broan-NuTone CV350 Central Vacuum


Answers :

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 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 cannister. Any help would be greatly appreciated. Thanks


A great way to check if your switch in the hose is bad would be to turn the hose sideways in the inlet. If the unit turns on you most likely need a new switch. ... Broan-NuTone CV450 Central Bagged Central System Vacuum
