Re: noisey fan

In my case noise was coming from the plastic blade rubbing against the sheet metal housing. I removed the motor and added 2 washers to the mounting screws. The washers acted as spacers and lifted up the motor/blade assembly with respect to the sheet metal housing. The blade no longer rubbed against the housing and the noise stopped.

Re: noisey fan

I had the exact same problem and repaired in a similar way than Solution #2 posted on Nov 15, 2008

I added a steal o-ring on the shaft to prevent the blade from going to low and rubbing against the metal casing! The key is to prevent it from lowering on the shaft.

Re: noisey fan

The bearings in the motor are probably failing/or dry.Locate the shaft of the motor going into it and spray wd-40 on it and see if this helps.

Should I lubricate my fan to stop a grinding noise?

Most hunter fan don't require lubrication, if you hear a grinding noise I would check the balance of the fan, if your hearing a grinding, and its not caused by being out of balance, then I would replace fan

I have a broan ceiling light and exhaust fan. We changed the light bulbs now the fan is really loud and makes noise it didn't before?

Did you use the recommend wattage bulb (or that was in there)?

If you used the same or a higher wattage bulb it may burn hotter. When bulbs "burn" (are on) they actually do burn-out and may get cooler (and not as bright).
Changing the bulbs may also have shaken dust loose, allowing the fan to turn more freely and quickly, and if the bearings/lubricated points which may have been worn now shake about causing more noise, or, dust got onto the fan blades causing them to be heavier on one part than another which will definitely cause it to shake about and make a lot of noise (like unbalanced clothes in a washer's spin cycle).

My bathroom Broan exhast w/light makes a constant clicking / tick tock sort of noise when the fan is not running. as soon as I turn the fan on the noise stops and then stops after I turn the fan off, only...

remove the cover and clean anything in the vent , check the fan for anything that could be touching it, as the back draft comes through the vent, something could just be touching the fan blade as this draft makes the blade turn slowly, which would create a ticking noise

Does this model fan require oil -- just noticed a little noise coming from the fan - sounds like it needs lubrication!!

Most household fans come with prelubed Bearings that are supposedly lifetime bearings, but a lot of times even these fail.

If you can disassemble this fan you might attempt it, but more than likely you will spend more time than the Fan itself is worth.

The other thing to check is to make sure that the fan Body is not rubbing against the Props anywhere.

Very loud during operation sounds like something got loose during gentle dusting of blades and base

It is possible that the cover must have pushed down or changed the fitting position and moved off to touch when in motion. All what you need is to use a good lader to access the fan-- put the power off and use a tester to see for any leak in voltage to the fan before you touch- now move the blades and listen to the rubbing,if so check the cover and tighten it up. If ther is any bearing noise from the fan use a goos spray from the outside along the shaft( WD40) to wash off any dirt and apply some good lubrication oil, allow it to run and reapply. I hope you try this out. Good day

You make this way too complicated. I just want to know in general, where to put some oil to stop the dry rub noise that I'm getting after my concord fan runs for a couple of hours. KISS approach is best...

The "squeaky" wheel does not always get the grease (read on).

Have you reviewed these possibilities:

I know - you said dry rub.

I don't work here, but I don't think they sell your information.

Getting lubrication into a ceiling fan is very difficult unless you take it apart, take it down and then turn it upside down.... Then spray WD-40 in around wwhere the fan blades hook up at. Then let it set for at least a couple of hours to let the lubricant work its way into the bearing. Turn it a bit and spraying more in every fifteen minutes or so will help to get it in there better.

Hampton bay fan makes squeeking noise

If the fan is fairly new, remove it and return it to Home Depot. It is almost certainly something that has fallen down into the motor and is rubbing loudly enough to make a squeak as the fan runs faster.

The fan itself has sealed lubrication and you don't have to lubricate it.
