Door gasket, thermostat, fan, and refrigerant circulation issues can reduce cooling performance.

Weak cooling is not always caused by low refrigerant. The thermostat, sensor, compressor, air channels, and even a loose door gasket can all prevent the refrigerator from maintaining a stable temperature.

If you notice excessive ice buildup, water collecting at the bottom, or a compressor running without stopping, the problem should be checked early. Timely service helps avoid bigger and more expensive failures.
