Repair Your Own Bathroom Exhaust Fan

Dear Mr. Electrician: My bathroom exhaust fan stop working after making noise for several weeks.  Is this an easy fix or do I need to have the entire bath fan unit replaced?

Answer: Usually repairing a bathroom fan is easier than a full replacement.  However if you don't like your current bath fan's performance or the location is not the best for shower steam removal, than you may want to consider a full replacement. 

I found that several models of Panasonic fans are terrific for replacing an existing fan as they are designed very well for this purpose.  Most bathroom fans on the market are designed for new construction only and can be tricky if not impossible to use to swap out an existing fan.  In ceilings where the depth and clearances are unknown, I would use one of the Panasonic WhisperFit bath fan models because they have a low profile.

During my career as an electrician I repaired and replaced many bathroom fans.  From those experiences I found that obtaining replacement parts for broken bathroom fans was more difficult and sometimes more time consuming than the actual physical work of replacing parts.

I put together a short Ebook that describes the process of fan repair and also provides a list of bathroom fan manufacturers and where to find replacement parts.

Has your bathroom fan stopped operating?  Is it more noisy than usual?  Is it underperforming?

As an electrician I have installed, replaced, and repaired many models of bathroom fans.  There are certain factors that contribute to the optimum performance of a bathroom exhaust fan.  There are also a few things that a homeowner can do to maintain a bathroom fan and keep it running for as long as possible.  One important tip is to be sure to obtain the correct replacement parts when attempting a repair.
