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