Bathroom Fan Repair
Dear Mr. Electrician: What is needed for a bathroom fan repair? The exhaust fan in my bathroom stopped working after making noise for several weeks. Does the entire bathroom fan housing need to be replaced? Answer: A successful bathroom fan repair begins with having the correct replacement parts. In many cases, a residential bathroom fan motor can be easily replaced. NOTE: Some text links below go to applicable products on Amazon, eBay, or my FREE Bath Fan Repair Book.

Consequently, the parts replacement can be almost as simple. The fan motor is held in place in the photo above with two screws supporting the bracket (Note the pear-shaped slots). The electricity is connected with a plug. The housing is already grounded from the power supply, so ground continuity is maintained when the motor gets mounted securely. BATHROOM FAN MOTOR REPLACEMENT The key to a successful bathroom fan motor replacement is getting the correct replacement parts. Many bath fan replacement parts are available, but identifying the correct parts can be a chore. A model number was labeled inside the housing or on the fan motor support bracket when your bathroom fan was manufactured. It is not the number on the motor itself, though that can be helpful and is worth writing down. The fan model number may be stamped into the metal, or a label may be glued inside somewhere. Before working on the fan, put a drop cloth down and wear a face mask and eye protection. Old bathroom fans sometimes have an abundance of dust and dander inside. Use a ladder when reaching up for the fan. Do not stand on the toilet! Read my post about safety precautions.

It is difficult to remove the old fan blades, which can get damaged. Sometimes the bath fan motor replacement is sold as a kit with bracket, motor, and fan blade. The factory has a replacement kit available for those with a Nutone 696N B Unit bathroom exhaust fan. The Nutone C350BN includes a motor, fan blade, and bracket, all ready to be snapped into place. Some Nutone and Broan model bathroom fans that the builder of your home initially installed have a retrofit bath fan upgrade kit available to change out the motor, fan blade, and grill while the existing fan housing remains in place. This is the easiest thing to do, and the manufacturer claims an improvement in noise and air movement. The kit is sometimes cheaper than buying the replacement parts. The bath fan upgrade kit is a Nutone 690NT and can be used to replace motors and upgrade several models of Broan and Nutone fans, but not all. Broan has an identical upgrade kit with part number 690 and a different...
