EVAP FROST
Samsung · Samsung RS22T5201SR 22 cu. ft. Side-by-Side Refrigerator
Excessive frost and ice accumulates on the evaporator coils behind the rear freezer panel. This blocks airflow through the coils, causing gradual temperature rise in both the freezer and refrigerator compartments. The defrost system should melt this ice automatically, but if the defrost heater, thermostat, or timer has failed, ice builds up continuously. First, perform a forced defrost using Samsung's diagnostic mode. Then diagnose and replace the failed defrost component. If the drain hole at the bottom of the evaporator housing is clogged with ice, clear it with warm water — a clogged drain prevents melt water from exiting and causes re-freezing.
