User Suggested Solutions

Check and replace the thermostat if faulty. Locate the thermostat inside the refrigerator, disconnect the power, and test the thermostat with a multimeter. If it shows no continuity, replace it with a new one.
Clean the condenser coils. Unplug the refrigerator, locate the coils (usually at the back or beneath), and use a vacuum or brush to remove dust and debris. Plug the refrigerator back in and monitor the compressor.
Check for refrigerant leaks. Inspect the refrigerant lines for any signs of damage or leaks. If a leak is found, it is recommended to call a professional to repair and recharge the refrigerant.
