How to Replace an Attic Fan Motor How to Replace an Attic Fan Motor

What You'll Need

Replacing the attic fan motor in your home can be a complicated job because it involves wiring. If you have to replace the motor, though, because it is making odd noises or just won't work anymore, you can.

Step 1—Remove the Motor

Turn off your fan and unplug it. You may need to remove the fan from its hole, but you should be able to reach the motor through the back of the fan. Take off the back using the screwdriver and locate the attic fan motor. Remove this by taking off the wires, making a note of which ones belong where, and unscrewing the motor from the base.

Step 2—Add the New Motor

Take your new motor and place it into the fan. Fix the wires into the correct positions using your pair of pliers. Then, screw down the connections to the attic fan motor tightly and replace the back cover. Screw this on and then add tape around the outside to secure it.
