The LG MEE63545701 defrost heater sheath is the OEM replacement part that keeps your refrigerator's automatic defrost cycle working correctly. When this heater fails, frost accumulates on the evaporator coils, blocking airflow and causing your fridge to warm up or stop cooling altogether. Replacing it restores proper defrost operation and protects your food.

✓ Model-Specific Repair Pages

The MEE63545701 heater sheath is a glass-encased resistive heating element that wraps around the evaporator coil assembly in LG French door and bottom-freezer refrigerators. During each automatic defrost cycle, the control board activates this heater to melt accumulated frost off the evaporator fins, ensuring consistent airflow and temperature regulation throughout the refrigerator and freezer compartments.

✓ Common Symptoms Fixed

Refrigerator not cooling properly or warming up over time. Frost or ice buildup visible on the back wall of the freezer compartment. Freezer section too warm despite compressor running. Fan running but no cold air circulating. Refrigerator cycling on and off more frequently than normal.

✓ Installation Tips

Unplug the refrigerator and allow it to fully defrost before beginning any repair. Remove all food and store it safely during the repair. Wear work gloves — the evaporator area may have sharp metal edges. Access the evaporator coil by removing the freezer back panel (typically 4–6 screws). Disconnect the heater wiring harness and remove the old heater sheath from the coil assembly. Install the new MEE63545701 heater sheath, reconnect the harness, and reassemble the panel. Plug the refrigerator back in and allow 24 hours for temperatures to stabilize before restocking food.
