Sometimes our kitchen ceiling fan smells hot, usually when first turning it on and not always with the lights on. It doesn't exactly smell like an electrical odor, just hot. Also sometimes there is a hum when it does this. Both usually go away after it's on a few minutes, but sometimes I turn it off and try again later. We've had it at least a year, but this has happened in the last several months occasionally. Do I need to have an electrician check it out?
