Purchase You Replacement Motor and Inspect

First, you will need to purchase a replacement SM345 evaporator fan motor. You can find these motors at most major appliance parts stores, or you can order one from us here at Supplies Plus.

Remove the Defective Motor

Once you have your replacement motor, it’s time to remove the defective one. Begin by disconnecting power to your refrigerator. Next, locate the evaporator fan motor housing inside your fridge. On most models, this will be located near the back of the fridge, behind a panel or grille. Use a screwdriver to remove the screws that secure the housing in place, then carefully remove the old motor.

Install the New SM345 Motor

Now it’s time to install your new SM345 evaporator fan motor. Begin by attaching the new motor to the housing, then secure it in place with the screws you removed earlier. When choosing where to mount the new fan, be sure that the fan is level, meaning the motor’s mounting points must sit on the same plane. Be sure not to over-tighten the screws, as this could damage the motor. Once the new motor is installed, replace any panels or grilles that you removed earlier, then restore power to your fridge.

Test Your Refrigerator

After installation is complete, it’s a good idea to test your refrigerator to make sure everything is working properly. Start by disconnecting power to your fridge, then open the door and check that the evaporator fan is not obstructed in any way. If everything looks good, reconnect power to your refrigerator and wait a few minutes for it to cool down. Once it’s cooled down, open the door and check that the evaporator fan is running properly. Additionally, check to make sure that the power source voltage, frequency, and phase match the motor’s nameplate data. If everything seems to be working fine, you’ve successfully replaced your SM345 evaporator fan motor.
