Having problems with your Broan-NuTone CV353 Central Vacuum ?

I have a nutone CV-750, and when I am using it, it will shut off and on.. What can I do?


Answers :

It sounds like you could have one of two problems. I would guess either a short in your house, or a bad relay. If you plug you hose in sideways it will bypass the low voltage wire in the hose. If the unit doesn't shut on and off then you have a short and need a new hose. If the unit continues to cut on and off then you probably need a new relay. The relay is really easy to change out yourself and there are places to buy online.

I have the Nutone 353 central vacuum. The last few times we have used it motor has shut down and then will come back up after an hour or so. Re-set switch does not seem to matter

I bought a roomba pro elite robotic floorvac at a tag sale from an elderly couple who apparently used this vac very little as it was very clean and she had never even used it enough to use the extra filters that came with it, she said it was just too much for her to bend down to work it or move it. i suspect she stored it but kept the battery in it. after charging it, it powers up and sings a little tune, but then shuts off. i cleaned everything, including the sensors. it still shuts off, do you

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

Over heating? My 10 gallon 4HP shop vac has started shutting off after about 30 sec. after I turn it on to use. It smells real hot after I shut it off. I have changed the filter and the bag, which did not solve the problem. Any suggestions on what the problem could be? It's only about 31/2 years old and I really don't use it all that much, mainly for getting up dust and cob-webs from my garage.

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

I have a DC 17. In the middle of vacuuming the vacuum stopped working when it was in the upright position. It only works when the head is down and i am using the bar. I can not use the extension bar, becasue when I put the vacuum upright it shuts off. Where is the problem?


Hi there, it's Jack at Dyson.\012 \012 Like most Dyson vacuums, DC17's main suction motor is protected by a thermostat which shuts the machine down if it starts to overheat. This could be due to a blockage, and the filter may also need a wash ... Dyson DC17 Animal Bagless Upright Cyclonic Vacuum

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 need a Dyson DC 17 Total Clean exploded parts diagream that shows the switch assembly. There are two small springs and a small plastic part that were loose inside the switch assembly. This caused the vacuum to shut off in the full upright position which is the position you use when using the wand.

Have a Centralux Aerus about 5 years old. Don't see a model number. There is suction but beater brush quit working. Was using for a few minutes, shut it off for a few minutes, turned it back on and suction only. Tried the reset button also. Tried the sidekick attachment and it works fine. There was no smell like something was hot. Belt is fine. Are there any fuses or anything else to try? This vacuum cleaner has not really been used that much, it is hard to believe the motor would need replaced


There probably is a loose wire in the handle near the switch or a wire off near the swivel elbow near the vac power head. With the right fastener tool to remove some screws you can fix it yourself ... Electrolux Centralux Vacuum

My Dyson Animal has good suction and works fine for actually picking up dirt, but when I use the vacuum with the roller, I hear a grinding/rumbling noise. Its only when I use the vacuum with the brush rotating. It does not happen hen I shut the roller brush off. The belt is fine. I cannot figure out what is wrong as there are no clogs, debris, or foreign objects stuck in the brush or in the belt. The noise seems to be the only issue. The vacuum picks up fine. It just doesn't sound right a

Vx550 issues Like most here, ours shuts down after a few minutes use. Ichecked everything and found the thermal protection was shutting it down.

Heven't fixed it yet, but I've pulled the motor to see what the specific issue is. As soon as I have the problem isolated and a solution, if possible, I'll post it here.

Last year my wife and I bought a new Dirt Devil Reaction All Surface vaccuum cleaner to replace the older Platinum Force. After using it a couple of times the new one gets clogged with dog hair easily and shuts down. I cleaned it out completely including the hepa filter but it will not handle the dog hair.

Roomba Schedular I have a Roomba Scheduler and it has worked great until recently. Suddenly it quit working. When it is charging the power light goes from red to green as it should, showing it is ready to use. When we turn it on to use, it will only go on for a few seconds then it shuts off like it is out of power. It is like it isn't really charged. Is there something I can try to make it work?


Let it charge for a full 24, or even 48 hours, regardless of the green light. If it still dies you probably need a new battery.. or worse. ... Roomba Robotic Floor Bagless Vacuum
