Official Jenn-Air side-by-side refrigerator parts

Replacing a compressor start relay in a JennAir side-by-side refrigerator

• Unplug the power cord from the wall outlet.
• Pull the refrigerator away from the wall. Remove the screws from the rear compartment cover and then remove the cover.
• Pry off the wire retainer holding the start relay on the compressor. Disconnect the wire harness from the start relay. Pull the start relay and run capacitor off the compressor.
• Transfer the run capacitor from the old start relay to the new start relay. Plug the new start relay with capacitor into the compressor terminals. Plug the wire harness into the new start relay. Reinstall the wire retainer to hold the start relay on the compressor.
• Position the rear compartment cover on the back of the refrigerator and reinstall the mounting screws.
• Plug in the refrigerator and push the refrigerator back into place.

Parts that can fail in your JennAir side-by-side refrigerator

• Condenser fan. The condenser fan is in the machine compartment of the refrigerator next to the compressor. It moves air across the condenser coils to help cool the hot refrigerant coming out of the compressor. The refrigerant is cooled before it moves through the expansion device and into the evaporator.
• Defrost bi-metal thermostat. The defrost bi-metal thermostat is a safety device attached to the evaporator coil. The defrost bi-metal thermostat shuts off the refrigerator defrost heater if the heater gets hot enough to damage the evaporator.
• Electronic control board. The refrigerator electronic control board controls the major electro-mechanical components in your refrigerator. When the electronic control board senses the compressor needs to run to cool the refrigerator, it sends voltage to the compressor and fans. It then receives input from temperature sensors to monitor the temperatures inside the refrigerator and freezer sections. With this information, the electronic control board controls the defrost cycle.
• Door gasket. The door gasket seals the gap between the door and cabinet to prevent warm air from leaking into the compartment.
