How Do You Replace a Freezer Thermostat?


To replace a thermostat in a freezer, remove the panels and any retaining clips, disconnect the thermostat wires from the terminal, remove the thermostat, place and connect the new thermostat, and reassemble the freezer. The necessary materials are a new thermostat, screwdriver and needle nose pliers.

Before starting the repair, unplug the freezer. Use a screwdriver to remove the screws from the freezer panels. Depending on the model, the retaining clips may also need removal. Locate the thermostat. For chest freezers, the thermostat is typically at the top. For other models, it is located either in the rear or underneath the floor panel.

Two wires join the thermostat to the terminal. Use needle nose pliers to pull the wires away from the terminal. Place the grip of the pliers near the edge of the wire, and pull gently to avoid damage. Once the wires are disconnected, pull the thermostat out.

Place the new thermostat in the exact location of the old one. Use the needle nose pliers to gently grip the end of the wire and connect it to the terminal. Repeat for both wires.

Replace any retaining clips. Place the freezer panels back in their correct position, and use the screws to secure them. Plug the freezer back in, and test the new thermostat.
