To replace a fridge thermostat, disconnect the fridge from power, remove the thermostat cover, detach the terminal wires, and remove the old thermostat. Install the replacement thermostat in the place of the old one, plug in the fridge, and reset the temperature in order to test the new thermostat.
- Remove the thermostat cover
Unplug the power cord from the socket to avoid electrocution, and locate the thermostat in the fridge. Use a screw driver to unscrew and remove the panel that covers the thermostat. If the cover does not have a screw, loosen the retaining clips to remove the cover.
- Remove the old thermostat
Use a needle-nose pliers to disconnect the two terminal wires from the terminal pin, and loosen the mounting clip or screw that holds the thermostat. Pull the old thermostat from the evaporator tube, and take it out of the fridge.
- Install the new thermostat
Attach the replacement thermostat to the evaporator tube, and connect the two wires to their respective terminals. Put back the cover, secure it with a screw, and plug in the power code. Reset the refrigerator temperature, and test the efficiency of the new thermostat. If the thermostat does not work, check it, and fix any defects.
