LG Refrigerator Error Codes

Complete list of LG refrigerator error codes with fixes.

What it means

A LG refrigerator code points to the system the control board could not complete, such as fill, drain, heat, door latch, sensor, or motor operation.

Common causes and symptoms

Common causes include blocked filters, restricted hoses, failed sensors, wiring faults, or control-board errors. Symptoms often include beeping, stopped cycles, standing water, poor drying, or a locked door.

What to try first

Turn power off before inspection, check the visible filter or hose path, confirm the door closes fully, then open the matching code guide for model-specific fixes and safety notes.
