LG Refrigerator Error Code Miracle Zone sensor error

This error indicates the refrigerator's control board has detected a failure in the temperature sensor circuit for the Miracle Zone compartment, specific to LG BEST models. The failure is caused by either a cut wire creating an open circuit or a shorted wire in the sensor's wiring harness. When this error is active, the Miracle Zone temperature graphics and text on the LCD display will turn off, signaling the compartment's temperature can no longer be monitored or controlled.

This error does not represent a safety hazard such as a fire or shock risk, but it does mean the Miracle Zone compartment is no longer being regulated to its intended temperature. Food stored in that compartment may not be kept at a safe or consistent temperature until the fault is resolved. Avoid storing perishable items in the Miracle Zone until the sensor issue is corrected.

If the issue is a simple wiring repair or connector reseat, the cost may be minimal, primarily covering a service call in the range of $75 to $150. If the Miracle Zone sensor itself needs to be replaced, parts and labor combined typically range from $100 to $250 depending on parts availability and local labor rates. Control board replacement, if needed, is a more expensive repair that can range from $200 to $400 or more.

Start by pressing and holding the SUPER FRZ and FRZ Temp buttons together for at least one second to confirm the error is present. Then inspect the wiring connected to the Miracle Zone sensor for any cuts, pinches, shorts, or loose connectors, as damaged wiring is the most common cause. If the wiring appears intact and properly connected, the sensor itself may need to be replaced.

A power reset will not permanently clear this error if the underlying wiring fault or sensor failure is still present. The control board will detect the abnormal sensor signal again after power is restored and re-display the fault. The error will only clear once the cut or shorted wire is repaired or the faulty sensor is replaced.
