What is the process for refrigerator thermostat replacement?

To replace a refrigerator thermostat, first unplug the refrigerator and locate the thermostat. Remove the old thermostat by disconnecting the wires and unscrewing it from the fridge. Install the new thermostat by attaching the wires and securing it in place. Finally, plug the refrigerator back in and test the new thermostat to ensure it is working properly.
