My boyfriend installed a new ceiling fan to replace the outdated one that was there - it works just fine, the lights, the fan - but almost every time after it has been turned off it will make a loud pop noise - it can take a while for it to make that noise and its not timmed enough to have someone listen for - but not long after its turned off it will make this loud pop like noise - can't figure out what this could be??

I am stumped on this so let us know if you ever figure it out.

I think mine is going the same thing. It's not "loud," but it sounds like a giant bug has flown into the metal fan base. Happens once or twice a few minutes after I turn it off.
