Whirlpool WP4387490 Genuine OEM SxS Refrigerator Defrost Thermostat

This Refrigerator Defrost Thermostat is a safety device that clips onto the evaporator in the freezer. The thermostat turns off the defrost heater in case it gets too warm in the freezer section. If your refrigerator does not defrost as expected, replacing the thermostat may alleviate this issue. To access the part, open the freezer door and remove the shelves, mounting brackets (if they release), and the ice bucket. After removing the back panel, mount the new defrost thermostat at the end of the evaporator. Replacing this part will require basic hand tools, such as a multi-screwdriver and a wire splicing tool, some disassembly of the refrigerator, and novice repair experience. Before installing this high-quality replacement part, remember to unplug the appliance or shut off the house circuit breaker to ensure safety.
