Amana ASI2175GRS 21.7 cu ft Side-by-Side Refrigerator with Ice & Water Dispenser Frost Build-Up Error Fix: Excessive Frost or Ice in Freezer

Frost is accumulating on the freezer walls, food, or evaporator coils. On frost-free models, the defrost system runs automatically every 6-12 hours to melt ice from the evaporator coils. If this system fails, frost builds up until airflow is completely blocked. Check: (1) Defrost heater — located behind the back panel inside the freezer, test for continuity. (2) Defrost thermostat — located on the evaporator coils, it closes the circuit when coils are cold enough to need defrosting. Test for continuity when cold. (3) Defrost timer or defrost control board — these initiate the defrost cycle. (4) Door gasket leak — warm, humid air entering causes frost. (5) Door left open frequently.
