Buy refrigerator thermostat

Some defrost systems use a refrigerator repair thermostat (a bi-metal switch) to prevent the defrost heater from overheating. The switch is normally closed. During a defrost cycle, the defrost heater causes the metal alloy in the switch to warm and as it does it curls back and breaks the circuit. As the metal cools, it makes a circuit again and the defrost heater starts heating again (as long as the defrost timer is in the defrost cycle). A defective thermostat can prevent the defrost heater from coming on or allow it to overheat which could result in heat damage or fire. Simply plug the refrigerator into the refrigerator thermostat and then plug the thermostat into the wall, then unwind the temperature probe and secure it somewhere inside the refrigerator. Just turn the dial on the thermostat to adjust your refrigerator or freezer from 20 - 8o degrees Fahrenheit.
