A faulty or damaged condenser fan can result in compressor overheating and thermal overloads. The condensor fan is located behind the freezer near the compressor. It may be necessary to remove an access panel to reach it.
How To Replace the Condensor Fan
Before replacing the condensor fan, unplug the freezer to avoid an electrical shock hazard.
If the fan blade is damaged, it can be removed from the fan motor and replaced separately.
The fan motor is held in place with screws and possibly a mounting bracket. Remove the bracket and the screws and pull the motor back away from the housing.
The fan motor is connected by two or three wires. Label the wire placement on the motor before disconnecting the wires. The wires are connected to the terminals with slip-on connectors or a plug. Firmly pull the connectors off of the terminals (do not pull on the wire). You may need to use a pair of needle-nose pliers to remove the connectors. Inspect the connectors and the terminals for corrosion. If the connectors are corroded they should be replaced.
Remove the fan blade from the old motor and install it onto the new motor. Connect the wires to the new motor and install the motor into the bracket or housing. Make certain that all of the screws are tightened securely.
Replace the access cover (if any) and plug in the freezer.
