Nutone PfMB 52II ceiling fan light working intermittently and sometimes won't go on at all. Fan works fine. Sometimes it goes on briefly when turning on the wall switch, other times not at all. Sometimes it will go on and stay on, but then the next time you try and turn it on nothing will happen.

It may be a faulty switch, or a faulty connection where the fan is connected. Check the connection and make sure the wire nuts are tight. If it were up to me, I'd replace the switch as a matter of course.

Before you go replacing or rewiring anything, send me pictures of the fan and switch. Is this one of those switches with the 4 small toggles?
