Prevention
Stop the fault returning
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 walk-in cooler 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 walk-in cooler to catch wear before it becomes thermostat fault.
