How to Replace a Thermostat in an Under the Counter Refrigerator

Unplug the refrigerator’s power cable from the outlet. Locate and remove the access panel, which leads to the thermostat. The panel will be located either on the back of the refrigerator along the back interior wall.

Identify the thermostat. The easiest way to determine which part is the thermostat is to look at the new thermostat you’re installing; they will have a similar appearance. An under counter refrigerator thermostat is rectangular-like in shape and will have two wires connecting to it.

Remove the thermostat from its location. If you see a screw or two holding the thermostat in place, remove them with a screwdriver. Most thermostats require you to tug the component or press a release clip.

Pull the thermostat toward you, giving yourself room to work with. Cut both wires near the base of the thermostat, exposing the wires. Take the replacement thermostat and remove about a fingernail length of insulation from each wire.

Line up the existing wires with the new thermostat wires. The wires are typically color-coded. Twist one set of wires together at the exposed ends, and then tie the wires together with a wing nut. Repeat the process for the other set of wires.

Push the wires inside the compartment area so that you can attach the access panel without any interference. Secure the thermostat. Give the thermostat a gentle nudge to ensure it’s in place. Attach the access panel and connect the refrigerator to a power source.
