LG French Door Refrigerator – Compressor Replacement

A compressor that does not start or run can be caused by several issues, including:

• Faulty start relay or overload protector

• Main PCB or inverter control failure

• Loose or damaged wiring or connectors

• Incorrect voltage supplied to the compressor

• Open or shorted compressor windings

• Internal electrical failure

• Mechanically locked or seized compressor

• Internal compressor mechanical damage

Diagnosis & Repair:
This LG French door refrigerator was not cooling because the compressor was not operating. The start components, wiring, and PCB/control system were inspected and tested, with no faults found.

Further testing confirmed an internal compressor failure. The defective compressor was removed and replaced. After installation, the sealed system was evacuated, properly charged with refrigerant, and tested to confirm normal compressor operation and cooling performance.

LG Compressor Warranty:
Many LG refrigerators include up to a 10-year parts warranty on the Linear/Inverter compressor. Labor coverage is generally shorter and varies by model and purchase date. Because this refrigerator was approximately seven years old, the compressor part may still qualify for warranty coverage from LG, although labor and other repair costs may not be covered. Always verify coverage using the refrigerator’s model number, serial number, and original purchase information. LG currently lists 10-year compressor parts coverage and 5-year labor coverage on many French-door refrigerator models.
