LG Refrigerator: tripping GFCI outlet

Professional Repair Guide

What is this symptom?

Is your LG refrigerator tripping the GFCI outlet? This issue may stem from insulation degradation, a faulty GFCI, or a damaged power cord. It's crucial to address this problem promptly to prevent further electrical issues or damage to your appliance.

Urgency: High

Important Tips for LG Models

LG official guidance for tripping breakers confirms ground faults in appliance or wiring can cause trips, but does not provide specific GFCI troubleshooting beyond standard electrical fault identification.

Possible Causes

Insulation degradation or moisture-induced leakage in internal refrigerator components

How to Identify: Trips often during defrost cycles or when moisture accumulates; fridge intermittently trips only on a GFCI circuit

Part: Defrost heater, compressor windings, fan motors

Faulty or overly sensitive GFCI outlet

How to Identify: Refrigerator runs fine on a different outlet or non‑GFCI protected circuit without tripping

Part: GFCI receptacle itself

Damaged power cord or plug insulation

How to Identify: Visible damage to cord insulation, cracks, animal chew marks, or continuity testing shows leakage or neutral‑to‑ground connection

Part: Power cord

Circuit overloaded or shared with other devices

How to Identify: Multiple appliances on the same circuit; GFCI trips only when combined loads operate

Part: Electrical circuit

Improper grounding or wiring issues in home electrical system

How to Identify: Other appliances also cause GFCI trips on same circuit, or trips persist with different appliances

Part: Home wiring / grounding

DIY Solutions

Test with alternative outlet or non‑GFCI circuit

Easy 5–10 minutes

Unplug the refrigerator from the GFCI outlet.
Plug the refrigerator into a different outlet to see if the trips continue.

⚠️ Safety First: Do not use extension cords as permanent solutions; this is for diagnosis only.

Inspect and replace GFCI outlet

Moderate 15–30 minutes

Tools Needed: Screwdriver

Turn off the breaker to the GFCI circuit.
Remove and inspect the GFCI receptacle for age or damage.
Replace the GFCI outlet with a new, properly rated unit and reset it.

⚠️ Safety First: Ensure power is off before working on outlet.

Visually inspect power cord for damage

Easy 5–10 minutes

Unplug the refrigerator.
Inspect the entire power cord and plug for wear, cracks, or exposed wiring.
Replace the cord if damaged (requires ordering a compatible LG replacement cord).

⚠️ Safety First: Do not plug in the appliance with a damaged cord.
