Having problems with your Broan-NuTone CV450 Central Bagged Central System Vacuum ?
Vacuum won't shut off
\015 I disconnected to two low voltage wires from the side of the unit and still won't turn off. I opened the top and disconnected one wire from the relay the two wires were connected to and still runs when I turn the power on. I disconnected one wire from the bypass ON/OFF switch on the side of the unit and same result. I'm thinking it's the relay that all the wires connect to. The model number is a CV554. What do you think and where's the best place to buy parts for this thing?\015
Definatly a relay. that common for an older system. also bagless sysems really aren't the greatest.
The relay is most likely the problem, they get burnt and the contacts stay together leaving the unit on. Try www.builtinvacuum.com for parts.

I have a hoover windtunnel upright vacuum, It will not shut off and I have to unplug it to do so. If I take apart the upper handle and manually flip the internal switch it works just fine, only when using the external switch on the handle, wont shut off.
This is a common problem with this machine. The switch has too much resistance to be turned on and off with the switch button and rod. If you put in a new switch, ( # 28161075 ), your problem should be fixed. ... Vacuums

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!

I purchased a brand new Eureka Pet vacuum, sorry don't know exact name but it the one that has the self cleaning duster on it. Last night I used the vacuum on my carpet, it was working fine until I accidently sucked up the corner of a scarf that was hanging off a couch. I shut the vacuum off, pulled out the scarf and and resumed vacuuming. Much to my dismay the suction on the vacuum had ceased. Can you tell me if there is a reset button on the vacuum? The vacuum does not appear to be damage

Shutting off my vacuum has been shutting off in middle of use and i dont know why its like its over heating and i cant use it again for almost an hour is there a solution to this? or do i need to get a new vacuum?
It has a built-in temperature sensor which prevents it to be damaged from overheating. That's why it shuts down. It just needs to be opened up and cleaned thoroughly. Start with the hose if it has one and let someone who is handy with electric applia ... Vacuums
When switching the vacuum (DC17 Animal) over to the hard surface setting (so the beater brush is not spinning), the vacuum shuts off. I cleaned the dust bin and checked the filter. I also cleared the beater brush of hair or debris that was wrapped around it. It still shuts off. Ideas? Thanks.

My electrolux oxygen vacuum cleaner shut off and will not turn back on. It's less than a year old, but I bought it off Craig's list--they were the orginal owner and they said they bought it in May of 2008. I've only used it a few times and it worked fine except for the last time when it suddenly just shut off. I thought maybe it had come unplugged and I didn't really worry about it because I was finished vacuuming. But, I went to use it tonight and it would not turn on at all--no lights, nothing

My Eureka Airspeed vacuum keeps shutting off after about 5 min...It takes for about 3 days to vacuum because it will not turn back on for several hours...and it is not clogged. What is the problem
Canister vacuum, as soon as hose is on, or air flow is disturbed, the vacuum shuts off. yesterday the vacuum sucked up tree netting, we pulled it out, and now the vacuum has those symptoms.

I purchased a Eureka C4910 last year and have a question that I am hoping you can answer. There are two motor actions with this vacuum, 1) the vacuum suction, and 2) the beater bar. The action of the beater bar is that motor is supposed to automatically shut off when the handle is in the complete vertical position assuming the vacuum is stationary, but then turn on when the handle is tilted toward the floor, assuming the vacuum is moving back and forth. The beater bar motor turn-on mechan

Hello, I have a problem with my Eureka Powerline bagged upright vacuum. It has a 12 amp motor and is model #4352, Type D. It was probably bought new in 1998. My problem is, while vacuuming today the motor seemed to slow down all of the sudden and then began smelling like burning rubber. I shut the vacuum off to check for blockages but could not find anything blocked. When I then turned it on again it runs but seems to only be running at 1/2 the motor speed and still has the rubber buring smell.
It sounds like a rubber sealing in the motor has come loose and is being constantly rubbed against the walls of the motor with would cause the smell and loss of motor speed caused by the fricton of rubber against the rod so if you can get to the moto ... Vacuums
