Prevention
Stop the fault returning
Keep condenser fins clean and airflow clear — the leading preventable cause of thermostat fault in warehouses cold chains.
Monitor cabinet temperatures daily and log deviations so thermostat fault is flagged before stock is lost.
Replace door seals at the first sign of perishing to stop the warm-air ingress that drives many thermostat fault callouts.
Book a service check ahead of peak trading so the display refrigerator under the heaviest load is not the one that fails.
