Question about Broan-NuTone CV353 Central Vacuum

2 Answers

I have a Nutone CV353 system in my utility room every time it

Run's it creates negative pressure in the room causing the gas hot water heater to back draft. Does Nutone make a kit of some kind to fit the top of the unit to bring in make up air from the out side?

Home Depot sells the unit would they know or have such a thing as an adapter?

Thanks in advance for any help.

Open a window, or the bathroom door if there is a vent in there it will draw in air from there, just be careful because if there is a bunch of dust up there it may fall out.

Central vac not sucking


Check for a plugged tube in the wall by listening to the motor when it's running. If it sounds like it's running too fast then there's an obstruction. If it sounds ok, then there's a disconnected tube somewhere in the system.

How do we get the brushes out of a nutone cv353 when there isno room to get at the nuts?


If you're referring to carbon brushes, I'd have to see a picture taken from above the unit, close enough to see the nuts to which you refer.

Nutone cv353 unable to stop


You may have a stuck relay or one of your access port switches may be bad. According to the owners manual: "A complete check of all Wall Inlet and Power Unit low voltage control lead connections (external yellow leads). Turn system off by removing fuse or tripping circuit breaker at
house fuse box."

Nutone Model CV353; runs for several minutes and then shuts off. After a couple of hours I can turn on again, but again only last a couple of minutes. Possible relay problem?


Check the filter. If it's dirty, thoroughly rinse it in cool water, then let it thoroughly dry before using. If you don't have an extra filter to use during this time, you should get one.
It could also be a clogged hose or pipe. These would cause the motor to overheat, thus shutting off. Check hose at end for suction. If weak or nonexistent, detach hose and try dropping a penny or dime, or marble, down the hose. If it comes out the end, the hose is probably clear. If this is the case, you need to check other outlets.

Nutone CV353 does not shut off, think it is the relay board


You probably have a stuck relay. You can try tapping with medium force next to where the low voltage wires are attached to the unit using the handle end of a hammer. Even if this works it's time to replace the circuit board. Take the unit to a local vacuum repair center for service.

I am in ecuador and have had a local "plumber" install a lpg tankless water heater for me. After more difficulty than there should have been it's up on the wall with the water and gas lines attached but it...


The system is ignited by turning on a hot water faucet causing water to flow through the unit activating the igniter.You could disconnect the gas line at the unit turn the valve on and off real quick and smell for gas.If there is air in the line you may have to let it run or purge the line just long enough to make sure gas and not air is comming out.You might want to have utility company do this if you have any worries .I would make sure it is set up for lpg and not natural gas. And then and this is quite often the problem the gas line feeding the unit should be at least 3/4 inch pipe and fairly close to the main supply and in no instance the last fixture in system unless the pipe sizing is adequate for the amount of gas the unit needs to run.If sizing is the problem sometimes rather than running new pipes your utility company might be able to adjust the pressure comming out of the tank to make up for it. Hope this helps good luck

Nutone cv353 central vac blew up


My guess would be that the motor is done. Impossible to diagnose for sure without seeing it of course. If you were happy with the unit before the trouble, a replacement motor will probably run $250-$300. If you are interested in a new unit, shop around. There are definitely better designed and more powerful units out there, although some of them can cost quite a bit more than $300. Good Luck!!

CENTRAL VACUUM SYSTEM


Disconnect the inlet piping from the unit and check the suction there. Be sure that the utility inlet on the unit is closed. If you have good suction, you have an open/broken pipe somewhere, or possible an inlet valve or vacpan that is not sealing when closed. The easiest way to find it would be to install your tubing back into the inlet of the unit, turn the unit on, and walk around the house listening for air leaks. Good Luck!!
