LG Refrigerator: tripping GFCI
What is this symptom?
If your LG refrigerator is tripping the GFCI, it indicates an electrical imbalance or leakage. This issue often arises even when the appliance seems to operate normally. Common causes include internal ground faults, a faulty GFCI outlet, or a damaged power cord. Addressing this promptly is crucial to prevent potential damage to your refrigerator or home electrical system.
Important Tips for LG Models
- No specific LG manufacturer documentation found; however, users recommend dedicated circuits and careful inspection similar to general refrigerators.
Possible Causes
Ground fault within the refrigerator’s electrical system
How to Identify: GFCI trips when refrigerator operates; multimeter continuity tests between live/neutral and ground show leakage; moisture around components
Part: Internal wiring, defrost heater, compressor, fan motors
Faulty or overly sensitive GFCI outlet
How to Identify: Other devices trip same outlet; refrigerator runs normally when tested on different outlet or non‑GFCI circuit
Part: GFCI receptacle
Shared or overloaded circuit
How to Identify: Multiple appliances on same circuit; removing other loads stops GFCI trip
Part: Circuit wiring/outlet circuit
Damaged power cord or insulation
How to Identify: Visible damage on cord, GFCI trips immediately upon plugging, wriggling cord changes behavior
Part: Power cord insulation
DIY Solutions
Test on different circuit/outlet
- Unplug refrigerator.
- Plug into a different GFCI outlet or regular outlet that is not GFCI-protected.
- Observe if it still trips the GFCI.
Inspect power cord
- Unplug the refrigerator.
- Visually inspect the entire power cord for cracks, cuts, frays, or exposed wires.
- If damage is found, avoid using the refrigerator until cord is replaced.
Next step

Confirm the diagnosis before ordering. An error code can identify the system involved, but it does not prove that a specific part has failed.
Most relevant component to inspect
Defrost Heater
Melts frost buildup on the evaporator coils during the defrost cycle.
- Typical part-only price
- $25 - $60
- DIY difficulty
- Medium
- Estimated time
- 30-45 mins
Where can I find the model number?
Check the rating label around the door, lid, frame, rear panel, or inside the appliance cabinet. Use the complete model number, including suffixes.
Verify the complete model and part number on the retailer's compatibility page before ordering.
Other parts options
Check related components first; use model search as a fallback.
Compressor
Compresses refrigerant within the sealed cooling system and requires specialized service equipment.
Power Cord
Supplies mains power to the appliance and includes the model-specific plug and terminal connection.
Model-compatible Refrigerator parts
Enter the complete model number to browse compatible replacement parts. This is a model-based parts search, not a diagnosis that a specific component failed.
