Bathroom fans help move moisture out of the room.
Bathroom exhaust fans pull humidity out of the room and disperse it into the outside air. The fan helps prevent mold and mildew development. If you're having problems with the exhaust fan, it could be several different issues, but luckily you can open up the fan fairly easily to assess the situation.
Instructions
1. Turn off the power to the bathroom by flipping the breaker switch. Test the fan switch to make sure that it's no longer powered. If the fan wasn't working to begin with, then try the light switch instead.
2. Remove the exhaust fan's cover. It should pop off when it's pulled.
3. Remove the motor from the housing by taking out the screws that hold it in place. Look behind the motor to see if it's plugged in. If not, plug it in and reattach it to the housing. Have someone flip the breaker and turn the fan on to see if it runs. If not, continue troubleshooting. If it works, put the cover back in place.
4. Take the motor out again and unplug it. Use the screwdriver to remove the electrical plate to get to the wiring connections. Inspect the wires to see if any are disconnected or loosely connected. Twist the wires back together and secure them with electrical tape and wire nuts. Plug the motor in and attach it again to see if it now works. If so, put everything back as it was. If not, remove the motor again to look for other issues.
5. Push the housing to one side. It is held in place above by brackets that are secured to the ceiling joists. They are sliding brackets that allow you to shift the housing in and out of place. Look up into the ceiling to see if the vent tube has become detached. If it has, reattach it to the vent slot with foil duct tape.
