Do I need to oil my ceiling fan?
If you own a ceiling fan that was manufactured before 1970, then yes, your ceiling fan likely needs to be oiled. This will apply to some fan entusiasts who own a piece of history. There are a number of brand name fans and certain models as well that need to be oiled. The Hunter original and many fans based on it require oiling. This includes the following manufacturer and model of fan:
One sure way to tell if your ceiling fan requires oiling, is to look
for the oil hole. Also, what construction is your ceiling fan?
Ceiling fans that require oiling will be heavier and of a material
like cast iron or the like. If your fan makes noises while spinning
like a grinding noise, rubbing, etc. then it may require oiling. Fans
that don't require oiling can still require it, depending
upon the environment the fan is in. Smoking around your ceiling fan
can cause it to get gummed up, or if it's in a dusty area as well.
The oil you want to use will be a non-detergent motor oil. Oils with detergents should not be used as they cause problems with the bearings. WD40 is not an acceptable method of oiling your fan. It can work to clean the fan but should not be used for oiling. Hunter also manufactures an oil that you can use as well.
