I have had an extractor fan with timer fitted to my bathroom ceiling for some time. Recently after a gas fitter had been working above it I noticed that water was dripping from the fan, I removed the fan, dried the unit with a hairdryer, refitted it and it worked fine for weeks but now when I switch the light off the fan only buzzes but does not come on until I switch the light off and then the fan operates ok for a few minutes.
Is the fan needing replaced.
