User Suggested Solutions

Clean the condenser coils. Unplug the refrigerator, locate the coils (usually at the back or bottom), and use a vacuum or brush to remove dust and debris.
Check and replace the thermostat if necessary. Use a multimeter to test the thermostat's continuity and replace it if it's faulty.
Inspect and clear any blockages in the air vents. Ensure that nothing is obstructing the airflow between the freezer and refrigerator compartments.
Check for refrigerant leaks. If you suspect a leak, you will need to call a professional to locate and repair it, as handling refrigerants requires special certification.
Test the compressor functionality. If the compressor is not running or making unusual noises, it may need to be replaced by a professional.
