Product Description
The bi-metal defrost thermostat is attached to the evaporator, and its purpose is to protect the evaporator from overheating when the defrost cycle is running. If there is frost building up in your freezer, or it gets too warm during the defrost cycle, there may be an issue with the thermostat. You can use a multimeter to determine if it is the thermostat or the heater itself that is faulty. If you do need to replace the thermostat, this is a genuine OEM part. As this repair requires some electrical work, please be sure to disconnect the power supply to your fridge before starting this project. You will need a Phillips screwdriver, a 1/4-inch nut driver, a flat blade screwdriver, wire strippers, electrical tape, and butt splice connectors in order to complete this repair.
