Refrigerator interior frosts up excessively and requires frequent manual defrosting due to failed heater not completing automatic defrost cycle.
Refrigerator section warms up while freezer remains cold, caused by ice blocking the evaporator fan and restricting airflow.
Frozen condensate pan and blocked drain result in water pooling under the bottom bin drawer and leaking onto the floor.
Ice buildup around the evaporator causes the cooling fan to strike ice, producing loud rattling or grinding noises inside the refrigerator.
💡 Pro Tip: How to Know If Your Defrost Heater Has Failed
Your part is likely the culprit if you notice any of the following:
⚠️ Thick frost or ice wall building up behind the refrigerator back panel
⚠️ Refrigerator section warm but freezer still cold — evaporator fan blocked by ice
⚠️ Water leaking under the bottom crisper drawer due to frozen condensate drain
⚠️ Multimeter reads open circuit (over 1 megohm) across heater terminals at room temperature
🛠 Diagnostic Tip: Unplug fridge and remove the back panel inside the refrigerator compartment. Locate the heater assembly on the evaporator coil. Disconnect the two-pin Molex connector and test resistance with a multimeter. A working DA47-00247H reads approximately 100 ohms. Open circuit = failed heater, replace immediately.
