There are a number of reasons why the bathroom extraction fan may not be working correctly. One reason could be that it has not been installed properly. Bathroom fans connect to duct work that should reach all the way to the home’s exterior, however, sometimes builders cut corners and only take the duct work into the attic space. This may not be immediately noticeable in the bathroom itself, but excess moisture in an attic space can damage materials and create an environment for mold. Another reason for the fan to stop working is dirt and dust buildup. This would be a much simpler fix and giving the fan a thorough cleaning may be all that is required.
What are some of the ways to tell if the extraction fan is not properly functioning? There are a number of visible signs which would indicate this. For example, an excess of moisture would build up on the ceiling and tile, paint may start to bubble up and peel and metal bathroom fixtures could begin to corrode.
If you have noticed any of these signs in your bathroom and are worried that the fan may not be installed correctly, why not have the fan inspected? This way you can find out the true source of the problem and work to fix it before it creates too much damage.
