Step-by-Step Guide to Replace a Commercial Kitchen Exhaust Fan Motor

Here is a step-by-step guide to help you replace a commercial kitchen exhaust fan motor:

Step 1: Turn off the Power

Before you start working on the exhaust fan, turn off the power supply to the unit. This will prevent any electrical accidents from occurring.

Step 2: Remove the Grill Cover

Using a screwdriver, remove the screws that hold the grill cover in place. Gently remove the cover and set it aside.

Step 3: Disconnect the Electrical Wires

Locate the electrical wires that connect the motor to the power supply. Use wire cutters or strippers to disconnect the wires from the motor.

Step 4: Remove the Fan Blades

If the fan blades are attached to the motor, use pliers to carefully remove them from the motor shaft. Note the direction of the blades so you can reinstall them correctly later. If the blades are not attached to the motor, skip this step.

Using a screwdriver, remove the screws that attach the motor to the exhaust fan housing. Carefully remove the motor from the housing and set it aside.

Step 6: Install the New Motor

Step 7: Reconnect the Electrical Wires

Using wire cutters or strippers, reconnect the electrical wires to the new motor. Make sure they are securely connected.

Step 8: Reinstall the Fan Blades

If you removed the fan blades, carefully reinstall them onto the motor shaft in the correct direction. Use pliers to secure them in place.

Step 9: Reinstall the Grill Cover

Align the grill cover back onto the exhaust fan housing and secure it with screws using a screwdriver.

Step 10: Test the New Motor

Turn on the power supply to the exhaust fan and test the new motor by running the fan. Make sure it’s running smoothly and quietly.
