Temperature fluctuations in commercial refrigerators are commonly caused by dirty condenser coils, faulty door seals, refrigerant leaks, improper airflow, or a malfunctioning thermostat. To prevent these issues, regularly clean condenser coils, inspect and replace worn door gaskets, ensure proper ventilation around the unit, and schedule routine maintenance with an appliance repair professional technician to check refrigerant levels and thermostat calibration. Proper loading practices—avoiding overpacking and blocking vents—also help maintain consistent temperatures and prevent system strain.
