A malfunctioning exhaust fan in your bathroom or kitchen can result in very unpleasant odors in these areas of your home. The good news is that it is possible to repair your fan without having to replace it with costly parts. Before you undertake your exhaust fan repairs, be sure to turn off the power to the fan.
First, you will need to remove the exhaust fan cover responsible for protecting the fan blade. If the cover is a little stuck, you may use a putty knife or flat head screw driver to score the edge around the cover of the fan in order to have it come off easily. One reason why your fan could fail to work is due to the buildup of mold or mildew, as well as dirt and grime. These tend to build up at areas where the fan blade is attached to the motor thus preventing the blade from spinning properly and eliminating air and moisture from the room. In the event that this occurs, you will need to remove the cover from the exhaust fan, remove the fan blade and then use a brush to thoroughly clean it. You will also need to clean out the area where the fan blade is attached to the motor.
Another common cause of malfunctioning exhaust fans is faulty wiring. You should check the wire connections from the exhaust fan motor to the power switch to ensure that these function correctly. In certain cases, all that’s required is that you tighten loose wire nuts to solve the problem. However, in the event that you are facing loose wire connections, you are better off installing new wire nuts than continuing to use those that you already have.
If all the connections to your exhaust fan are functioning well, you will need to check for other common problems such as dead motors. If the only problem with your exhaust fan is a dead motor, you don’t have to buy a brand new fan. This is because you may simply replace the motor by buying a replacement at a home improvement store.
