Unplug the appliance
Disconnect your LG French Door Refrigerator from power. For refrigerators, transfer perishables to a cooler.
Locate the thermostat
In refrigerators, the thermostat is behind the temperature control dial inside the fridge compartment. In ovens, it is usually behind the control panel or the rear panel, connected to a capillary tube.
Test with a multimeter
Disconnect the thermostat wires and test for continuity. The thermostat should show continuity when set to a cold/on position and open circuit when turned off. Replace if it fails either test.
Install replacement
Connect the wires to the new thermostat terminals. Route the capillary tube exactly as the original was positioned. Secure the thermostat in its mount.
Test temperature regulation
Plug in and set to the mid-range temperature. For refrigerators, verify it reaches 37°F within 12 hours. For ovens, use an oven thermometer to verify it reaches the set temperature within ±15°F.
