When a freezer starts building up thick ice around the internal panel, it usually means the automatic defrost system has failed. For this job, we had to systematically melt the heavy frost accumulation covering the evaporator coils using a portable steamer, taking care to protect the internal plastic liner and control components. Once the ice was fully cleared, we tested the defrost heater, thermostat, and timer assembly to locate the faulty component, replacing the failed part to ensure the unit can cycle properly again without choking up with frost.
