To reset a commercial refrigerator compressor: Unplug the unit or turn off the power at the circuit breaker. Locate the control panel and turn off both the refrigerator and freezer settings. Wait at least 5 minutes to allow the compressor to fully depressurize. Restore power by plugging the unit back in or turning on the circuit breaker. Reset the temperature controls to the desired settings. Allow 24 hours for the temperature to stabilize before restocking. Note: If the compressor frequently requires resetting, it may indicate a more serious issue requiring professional diagnosis and repair.
