Question about Broan-NuTone N-769RF Combination Light Fan Exhaust Fan

1 Answer

Noisy fan We just moved in to a new place and the fan is really loud. Kind of like a whirring noise but no grinding. It's been adjusted once already by the builders but it's already doing it again 2 weeks later. Any quick suggestions?

Re: Noisy fan

We had our house built with the same Nutone fan/light units in all 4 bathrooms. Moved in in 2002. One of the units starting making a loud noise last month. I popped the plasic cover off the light, then carefully pulled out the bulb, then unscrewed the wingnut in the middle. That allowed removal of the light assembly. Then I had access to the blade and motor. I found a lot of dust had collected on the motor and blade. I blew most of it off with compressed air (like what you would use on a computer), then used an electronic cleaner on the motor, then wiped off the blade and motor with a clean cloth.

I then crossed my fingers and turned on the fan.... It worked! It was quiet again. I waited a week before posting this. The fan is used every day. It is still quiet today.

If it ever needs replacing, I saw that Nutone sells the motor alone for about $22, that's a lot better than replacing the whole unit for around $70.

Minka f502 is noisy - how do you tighten the screws that attach the fan blade to the motor hub?

With a screw driver? And perhaps you also clean all blades. Sorry if you already did that.

My Hawkins 44" fan makes a humming noise when the fan is going. The faster the speed the louder the noise. With light on only , no noise. My assumption is it is electrical. Any advice would be welcomed....

Unless it is really loud, the noise you describe is quite normal. Often, at higher speeds the whooshing of the blades will mask some of the motor sounds. we have found the Hunter fans to run the quietest.

Fan is wobbling and noisy--cannot figure how to tighten the light fixture part of fan

I have a number of ceiling fans and its usally wise to just check that each blade as all the washes and fixing. As leaving just a washer out can alter the whight and balance.Some noise is to be exspected till they bed in so to speak unless they wobble really bad

Hampton Bay fan has a grinding noise

I have worked on many fans because this fan is ten years old. I want to say that this fan has ball bearings in it. Have you tryed WD-40? If so did it work? Are you able to look inside, through the top of the fan to see if some thing is in its way?

Bad motor bearing?

If you know how (and have the tools;PULLER,nut drivers,slotted and phillips screw driver,hammer,deep socket set,dikes,vise,work bench,and some high temp bearring grease) to take things appart in general, you should be able to disassemble the fan motor and either pull bearings off shaft and replace or repack w/high temp grease if not sealed bearrings. If cannot aquire a puller for removal then attempt to blow all dirt/dust off bearring and try thumbing some motor oil (or vegetable oil if no motor oil available) while turning bearing on shaft back and forth till bearrings free up.Then reassemble electric fan motor reverse disassembly(be sure to keep parts staged as they come off for reassembly in area off the work area) "NOT" over oiling the bearrings into electrical/copper areas.

Noisy table fan - Vornado silver swan

the electric motor bearings and/or brushes have worn. soft metal screws is an indication of the quality of the motor.not good. sometimes units are of nice design, look and high price but they throw in a cheap chineese motor. all you can do is put a few drops of oil on the motor bearings, its ok to do when this worn out

Hello janeknows. The shaft of the fan motor may have a bearing gone bad. Follow these steps to locate problem. #1-turn power off by tripping the breaker, place your fingers on the shaft surrorting the blades & SLOWLY rotate the blades feeling for a catch or bump. A bump felt I suggest replacing the motor. No bump #2- remove the screws holding the cover supporting the control switches. Located among the wiring is a box with 2 or three wires. This is a capacitor. Note the info on the capacitor (1.4mf125v). Contact the fans Mgfr they may send you one for free if not visit your local hardware store and ask. Replace the unit using the wire caps in the unit or snip & strip the wire using new wire caps. Note witch wire went where. Turn power on and test operation.
