We safely thaw the coil, diagnose the trigger — charge, defrost, airflow or fan — repair the root cause, and restore clean coil operation so cooling returns and stays.
Industry context

A supermarket has little margin for a cold chain that drifts. High-footfall retail refrigeration protecting perishable turnover. We plan the fix to end the risk, not just the symptom.

Prevention
Stop the fault returning
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 cooler under the heaviest load is not the one that fails.
Keep a documented escalation path for temperature alarms so evaporator coil frozen is answered in minutes, not noticed at close.
