Is a burning smell from an LG refrigerator an emergency?
Treat it as urgent. Turn it off and unplug it or switch off its breaker, and do not use it again until the cause is found. If you see smoke or flames, or smell gas, get everyone out and call 911.
Symptoms & causes
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.
Tools & parts
You will need a multimeter for testing electrical continuity and voltage, which is crucial for checking faulty components. A basic screwdriver set (Phillips and flathead) will be necessary to remove access panels and component covers. Depending on the faulty part, you might need a replacement LG compressor start relay or a new condenser/evaporator fan motor.
Safety first
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.
When to call a pro
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.
Questions people ask
What causes a burning smell in an LG refrigerator?
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.
Is it safe to use my LG refrigerator if it smells like burning?
No, it is not safe. Immediately unplug the refrigerator to prevent potential electrical fires or further damage to the appliance.
How can I identify the source of the burning smell?
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.
