LG Refrigerator Error Code ICE MAKER FUNCTION ERROR

This error means the LG refrigerator's control system has recorded more than three failures involving the ice maker, specifically ice ejection errors or horizontal leveling errors. When this threshold is reached, the refrigerator enters an error mode and suspends ice maker operation. The error applies only to models equipped with an ice maker kit and requires a test cycle or component repair to resolve.

Start by pressing the Test S/W button on the ice maker to initiate a test cycle and attempt to reset the error. If the test cycle completes, monitor the ice maker for recurring faults. If the error returns, inspect the ejector motor for signs of failure, check that the ice maker assembly is properly leveled and securely mounted, examine the wiring harness for damage, and verify adequate water supply pressure and a clean inlet valve screen.

Repair costs depend on the root cause. If the fix is as simple as re-leveling the ice maker assembly or cleaning the water inlet screen, there may be little to no parts cost involved, with labor fees typically ranging from $75 to $150. If the ejector motor or the full ice maker kit assembly requires replacement, parts and labor combined typically range from $150 to $400 or more depending on the specific model and local labor rates.

A standard power reset alone may not permanently clear this error because it is triggered by a cumulative count of three or more faults. The correct reset procedure is to press the Test S/W button on the ice maker assembly, which forces a test ejection and water fill cycle. If that cycle completes successfully, the error counter resets. However, if the underlying cause is not fixed, the error will return once three more faults are logged.

Yes, the ICE MAKER FUNCTION ERROR affects only the ice maker function and does not impact the refrigerator or freezer cooling systems. Your food will remain properly refrigerated and frozen. You can continue using the appliance normally while you diagnose and repair the ice maker issue.
