Our AI has analyzed millions of service records for LG appliances. We know exactly what broke.
A burning smell emanating from your LG refrigerator often indicates an electrical component is overheating, which can range from a plastic-like odor to a more acrid electrical burning smell. This could be due to a failing compressor start relay, a seized fan motor (condenser or evaporator), or even a short circuit in the wiring. You might also notice the refrigerator struggling to cool, or in severe cases, see smoke or melted plastic near the back or inside the freezer compartment.
You will need a multimeter for testing electrical continuity and voltage, typically costing between $20-$50 USD, which is crucial for diagnosing faulty components. A basic screwdriver set (Phillips and flathead) will be necessary to remove access panels and component covers, usually priced from $10-$30 USD. Depending on the faulty part, you might need a replacement LG compressor start relay ($30-$70 USD) or a new condenser/evaporator fan motor ($50-$150 USD).
Immediately unplug the LG refrigerator from the wall outlet as soon as you detect a burning smell to prevent potential electrical fires or further damage. Always ensure the appliance is completely de-energized before attempting any inspection or repair to avoid severe electrical shock. Allow any suspected overheating components to cool down fully before touching them, as they can cause burns.
If the burning smell originates from the compressor itself, indicating an internal failure or seizure, specialized tools and refrigerant handling expertise are required, necessitating a professional technician. Extensive damage to the main wiring harness or a burnt-out control board points to complex electrical repairs that should only be handled by a certified LG appliance repair expert. Any situation involving active smoke, flames, or a strong, persistent electrical burning smell after unplugging warrants immediate professional intervention due to significant safety risks.
Often it's an electrical component overheating, such as the compressor start relay, condenser fan motor, or evaporator fan motor. Dust buildup on these components can also cause them to overheat and emit a burning odor.
No, it is not safe. Immediately unplug the refrigerator to prevent potential electrical fires or further damage to the appliance.
After unplugging and allowing it to cool, carefully inspect the compressor area at the back, and the fan motors inside the freezer and behind the kickplate. Look for melted plastic, scorch marks, or unusual residue on electrical components.
