I would recommend just replacing the motor's in the fans. It is a lot easier than taking the whole unit out to replace it. The motor for your fan sells for about $65.00.

Outside unit will only run for a short amount of time with A/C before the fan stops turning and starts humming, squealing/screeching and the top of the outside unit gets hot.


The bearings are bad in the motor and after the fan runs enough it eventually gets hot, making the bearing screech and the fan locks up. Need to replace motor again. See if it has a warranty. The reason it gets hot is because the fan is what removes the heat from the coil and if the fan isn't running there is nothing to cool it off so to speak.

15 year old bath fan/light noisy. rectangular 2 bulb model 164A-D


Could be that dirt and dust have collected on the fins over the years and are throwing them out of balance. You could try cleaning the fins on the fan.

The bearings may also be wearing out.

15 years is a good life for a fan.

New/Installed bath fan squeals. If I pull down on the motor housing it stops. After a while, it squeals again.

If the light and fan do not work, do I need to replace the entire unit or just the motor/


I agree that it would be cheaper and a better investment if you were to just buy a new one. You never know what all it might need either so it's best you call a pro so he can pinpoint the issue for you.

You should first be sure your filters are clean and that your ductwork is clear.

See this link for a bulletin that may address your problem.

Otherwise, see this link in case you have a sticky door switch or relay.

My friends Coonara heater fan is soooo loud and she needs to know how to fix it to stop driving her nuts.


It depends on what type of noise "loud" is. If it is rumbling or vibrating the whole unit, you will have to remove the buildup of dirt from the fan, to get it back into balance. If it's a squeal, the motor bearings need lubricated. Just one or two drops of 3in1 oil or even motor oil will work. Take a look inside and make sure none of the unit's insulation came loose and might be rubbing against the fan. Your unit might have 2 stages so, one of the fans will be hidden unless you remove the internal baffle.

Does the motor for a nu tone bathroom fan #86933-000 supposed to have 2 mounting studs opposite the shaft end? 8664RP


Yes. This motor has two studs opposite to the shaft.

Here are some pictures:

It is actually a better value to purchase the motor assembly S97017706 or S97017705, both fit.

Save yourself the grief and buy a new fan. Either replace the whole unit or take the fan from the new unit and install it in the old fan chassis. It will be a lot less painful than trying to troubleshoot the old unit.
