Having problems with your Broan-NuTone CV750 Central Vacuum ?

NuTone CV750 Central Vacuum won't shut off. The on/off switch on side of unit has no effect. Did continuity test on switch, it tests ok. I've disconnected the low voltage wiring at the side of unit, that had no effect.


Answers :

I will assume that you disconnected the switch from the circuit when you did the continuity test -- that is really important.
\015\012If so, then i think that the relay inside the top of the unit is stuck on, or the low voltage wires (inside the top) going to the relay are shorted together.
\015\012You can easily remove the top after removing 3 (or 4) screws from the upper side of the unit. Be careful to align the vents in the top with the cooling ducts from the motors when replacing the top.

The last time the vacuum cleaner was used the outlet sparked causing it to smoke when turning on vacuum cleaner. I replaced the outlet and plugged it in and things seemed o.k. Today I turned on the vacuum, it stayed on for a mili second and went off. I checked the switch on the vacuum and it showed voltage coming and going, but would not turn on again. I checked all the wires in the area of the switch all seemed o.k. I thought maybe there might be a short in the cord. When I went to plug

I have a 6550 that just stopped working. I had the on/off switch tested to find out that it was dead. I replaced it and still the machine does not work. Could the wiring in the handle be bad? How do you test if the motor is still good?

Nutone Broan CV556 runs continuously and will not shut off until I unplug it.. I disconnected the low voltage wires and it still runs when I plug it in. Inside the top of the vacuum are 3 electrical devices - one looks like a transformer wire -- one is a rectangular electronic black box. The third is an on off rocker switch. Which piece it likely to be shorted out? It is about 8 years old.

Motor/Fan does not run. I have removed and taken the top of the canister plastic motor housing apart and tested for power. I have power through the cord to the switch and power from the switch to the two wire terminals. I have not removed the motor. Looks like I will need special tools to take out the motor. The Vac looks almost new. It has been setting for several years. What do you think?

Power Issue Hi...my Miele vacuum cleaner (S314) will not turn on, unless I lean it on its side (the side that the power switch is on). I took it apart and the wires are all well attached, and I do not see any issues with the connectors. Is this a common problem with an easy fix? Thanks! Todd

The power head of my DC 21 keeps cutting off as soon as I start moving the hose around. The only way to get it going again is to step on the main switch on the canister, then the whole cycle of off and on starts again. I have replaced the entire power head and tested the continuity of all the wires in the hose and they are good. The repair shop says the PCB is bad but can not get one. What can I do ?


Not much. my only suggestion is to dig through the internet and try and find that pcb it may take awhile but it would be worth a shot. if you dont think you can make the repair take it to repair shop with new pcb and let them do it. ... Dyson Genuine DC-21 "Stowaway" Spare HEPA Filter, Dyson
