The ice maker thermostat, also known as bi-metal device, regulates and controls the activation of the icemaker ejection cycle. The thermostat lets the ice maker know when it is cold enough to produce ice. If your ice maker is not making ice or not dispensing ice, you may need to replace the thermostat. This is a genuine OEM part and comes with two retaining clips. Please remember to disconnect power to your refrigerator before starting your repair.
