Ways To Repair Your Bathroom Fans

Bathroom fans might need to be repaired if they do not perform their primary function, which is air ventilation in your bathroom, or if they are making a loud, unpleasant noise each time you switch them on.

Repairing the bathroom exhaust fan usually involves replacement of its electric motor. Replacing the motor does not require replacing the entire bathroom fan unit. Most often it is only the motor that needs to be replaced. The first step in replacing or repairing your bathroom fan is to remove it. The removal of your bathroom fan depends on the type of cover or the fan grill used to shield the motor of the fan and also the way it is mounted in your bathroom. Most bathroom fans can be disassembled easily with the removal of a few bolts or screws.

Precautions to Consider While Repairing Bathroom Fans

Before initiating the removal, turn off the power supplied to the fan from the main electricity panel. Check the electrical wires attached to the motor of the fan with the help of a circuit tester, to confirm that the power is off.

Wear safety glasses to prevent any debris from entering your eyes.

The following points summarize the procedure that should be followed for repairing your bathroom fans:

Removing the Cover

If the cover is fixed using screws within its vent grills, then use a screwdriver to loosen the screws and detach the cover by releasing it from the screws.

If the fan is ceiling mounted with the help of hangers located under a bulb, remove the translucent bulb cover and then the bulb to expose the screw or the nut that is holding the cover in place. Once the nut is removed, the cover and the light assembly will be detached from the ceiling exposing the motor. Be cautious not to perform this step when the bulb is hot.

Be careful while removing the cover. You do not want to scrape the paint off your bathroom wall or cause a dent on it.

Removing the Electric Motor and Replacing it with a New One

The electric motor of the fan is exposed after the cover is removed. The motor is plugged in the fan housing box or mounted inside it with the help of screws. Once the motor is released from the housing box, it should be detached from the wiring harness. Before removing the motor, uninstall the blower wheels off the motor shaft.

Remove the housing box of the fan and vacuum it to remove the accumulated dust. Note down the information of the manufacturer and the model number located on the housing box which will prove helpful in finding a replacement for the motor.

Using the information in the above step, go online to check if the motor can be ordered online and check its availability in the local hardware stores. If it cannot be ordered online, take the motor along with you to a local home improvement store or a hardware store and find an equivalent motor.

Once you have found a replacement for the motor, install the blower fan onto the new motor’s shaft. Mount the motor into the fan housing box with the help of screws or just plug it in and connect it to the electric wires.

Reinstall the cover that was removed over the new motor.
