How Do You Change A Broan Bathroom Fan Motor

How to Change a Broan Bathroom Fan Motor

A bathroom fan is crucial for maintaining proper ventilation and preventing moisture buildup, which can lead to mold and mildew growth. Over time, the motor in a bathroom fan can wear out or fail, requiring replacement. Broan, a leading manufacturer of bathroom fans, offers a range of models with readily available replacement motors. Replacing a Broan bathroom fan motor is a straightforward DIY project that can save you money and extend the life of your fan.

1. Disconnecting Power and Preparing the Fan

Before attempting any repairs, it is essential to prioritize safety by disconnecting power to the bathroom fan. Locate the circuit breaker controlling the fan and switch it off. To confirm power is off, use a non-contact voltage tester to ensure there is no electricity running through the fan wiring.

Once the power is off, remove the fan cover. This usually involves unscrewing a few screws holding the cover in place. Next, locate the motor housing and remove the screws securing it to the fan housing. The motor housing should now be loose and ready for removal.

2. Replacing the Motor

With the old motor removed, you can begin installing the new replacement motor. Ensure the new motor is compatible with your Broan bathroom fan model. The motor typically has mounting holes that align with the holes on the fan housing. Carefully align the new motor and secure it with the screws provided.

Connect the wiring from the new motor to the fan housing. Match the wires by color (typically black to black, white to white, and green to green). Ensure the wires are tightly secured in the terminal blocks. If there are any doubts about wiring, consult the Broan fan manual for specific instructions.

3. Testing and Reassembly

Once the new motor is connected and securely installed, restore power to the bathroom fan. Turn the fan on and verify it is running smoothly and quietly. If any issues arise, double-check the wiring connections and ensure the motor is correctly mounted. If the fan continues to malfunction, it may be necessary to consult a qualified electrician.

If the fan operates as intended, reassemble the fan housing and cover. Make sure the fan cover is securely fastened with its screws. Finally, test the fan again to ensure it is working correctly.
