Nutone WA6500 range hood fan motor noisy

Motor gets very noisy after running 30 minutes. Lowered the speed on the control knob but the noise is still there. Turned off blower motor and back on after 20 minutes and noise went away.
Cleaned and lubed with light oil but noise came back again after using 30 minutes. Fan removed and noise is still there.
Is it the motor or the speed controller?

Re: Nutone WA6500 range hood fan motor noisy

We have the same product, 18 months in use and the very noisy motor has finally seized up. I contacted the manufacturer and was advised that I need a new motor, motor mounting bracket and fan rotor. The agent was not able to quote me a price for the parts but stated that even though my 1-year warranty had expired, if I faxed them a copy of the original sales reciept they could possibly send me the parts for free under the original warranty agreement. I've done as they asked but haven't received a reply as yet. After reading about all the problems with this product I'm tempted to dump the whole unit and try to find another manufacturer that has a reliable and QUIET range hood.

The fan motor makes a noise but doesn not start rotating, if you rotate the fan the motor kick in and continues to work until it os turned off.

The motor probably is not starting because the bearings are a bit stiff....
Take the hood apart and give it a good cleaning, being careful to not get the motor wet...
Then if you can get the hood in a position to run some light motor oil down the shaft and into the motor... spin the shaft as you do this... get oil worked into the motor bearings then it will probably work again...

Noisy fan or motor?

HI. The most common issue here will be with a loose motor shaft. This is the part that the fan blades are mounted on. When this occurs, the looseness will cause the motor, and shaft to wobble, thus, causing this noise you here at high speeds. The wobble is less violent during the slower speeds, so it is not loud, in this case.

The second issue will be a warped fan blade. This will cause the fan to rub against the shroud, thus, creating the noise, as well.

If the shaft is loose, or bent, the entire motor will need to be replaced. Now, if the fan blade is warped, you can, simply, unscrew the blade from the shaft, and replace it(on most model)

Nutone motor is ****

Are you replacing the blade at the same time? An unbalanced blade can ruin the motor before its time.

Nutone range hood fan motor quit

You can remove it and bench test it by applying 120 volts to the fan leads. Do you know how to do this -- it can be dangerous if not done properly.

You can also use a voltmeter to measure resistance and check continuity of the motor coils.

Very noisy operation

Yes....this will throw than fan unit out of balance almost the same way the tires on your car get out of balance. The wobble effect at high speed makes tons of noise.
