LG Refrigerator Error Code Freezer 2nd Digit g

This error code indicates a fault in the freezer defrost circuit. The control board has detected one of several possible problems: a disconnected or damaged wiring connector, a cut or shorted wire, a defective defrost thermistor, or a defrost heating cycle that ran longer than 80 minutes without completing. The first step is to measure resistance across the purple and white wire terminals of the defrost heater to determine whether you have a short circuit or an open circuit.

You should address this error promptly. A failed defrost system will cause frost to accumulate on the evaporator coils, which progressively reduces cooling performance in both the freezer and fresh food compartments. A shorted heater element also carries a risk of prolonged uncontrolled heating if the thermal protection fails. Continued use without repair can lead to food spoilage and potential component damage.

Repair costs vary depending on which component has failed. A defrost thermistor typically costs between $15 and $50 for the part alone. A defrost heater assembly generally runs between $30 and $100. If the repair requires a service technician for diagnosis and labor, total costs including the part could range from $100 to $300 or more depending on your location and the specific failure.

Some causes, such as a slipped connector, can be fixed without replacing any parts. However, faults involving a shorted heater, open circuit wiring, or a failed thermistor will require replacing the defective component. If you are comfortable using a multimeter and accessing the freezer evaporator panel, you can perform the resistance test yourself. For any work involving heater replacement or wiring repair, basic appliance repair skills are needed.

A power reset may temporarily clear the error code, but it will return if the underlying fault in the defrost circuit has not been corrected. The control board will attempt another defrost cycle and re-detect the same problem. A reset is useful for confirming whether the fault is intermittent, such as a loose connector, but it is not a repair.
