User Suggested Solutions

Check and replace the heating element. Unplug the refrigerator, access the heating element (usually located near the evaporator coils), and test it with a multimeter for continuity. If it's faulty, replace it with a new one.
Test and replace the thermostat. Locate the thermostat inside the refrigerator, use a multimeter to check for continuity. If it fails the test, replace it with a compatible model.
Clear any blocked air vents. Inspect the refrigerator's interior for any obstructions that might be blocking airflow. Remove any items blocking the vents to ensure proper circulation.
