User Suggested Solutions

Inspect the sealed system for visible signs of damage or leaks. Use a refrigerant leak detector to identify any leaks. If a leak is found, the damaged section of tubing must be replaced and the system recharged with refrigerant.
Check and replace door seals if they are damaged or not sealing properly. Ensure that the refrigerator is level to maintain proper door alignment.
Test the compressor functionality. If the compressor is not running or is making unusual noises, it may need to be replaced. This typically requires professional assistance.
