Prevention
Stop the fault returning
Book a service check ahead of peak trading so the display refrigerator under the heaviest load is not the one that fails.
Keep a documented escalation path for temperature alarms so thermostat fault is answered in minutes, not noticed at close.
Schedule quarterly preventative maintenance on your display refrigerator to catch wear before it becomes thermostat fault.
Keep condenser fins clean and airflow clear — the leading preventable cause of thermostat fault in restaurants cold chains.
