A couple of Thanksgivings ago a water pipe broke in my attic and flooded the bathroom ceiling before I turned the water off. Ever since then I have had a problem with the flourescent fixture. (48", 2 bulb). It seems that ever time my daughter takes a shower the light decides not to work. I just found this reason out. I have known for awhile that it was tempermental; working sometimes and not another. I just didn't know the reason. Yesterday I disassembled the fixture, checked out the wiring, had solid 120, reassembled the fixture making sure all of the connectors were tight. If moisture in the bathroom is the problem how do I insulate the light fixture against that. I am also considering a new exhaust fan.
