LG Refrigerator Error Code Mid Pantry-Sensor Error

This error means the main control board has detected a fault in the temperature sensor circuit for the Pantry Room compartment. The sensor, known as an NTC thermistor, monitors the temperature in that zone and sends a corresponding voltage signal back to the main PCB. When that voltage falls outside the expected range of 1.0V to 4.5V at connector CN30-9 to CN76-1, the board registers this error. The fault can stem from a failed sensor, damaged wiring, or a loose connector.

The refrigerator may continue operating in other compartments while this error is active, but the Pantry Room temperature may not be accurately controlled. This means food stored in that compartment could be at risk of improper temperatures. It is best to address the error promptly and avoid storing perishable items in the pantry zone until the sensor is repaired.

Repair costs vary depending on the root cause. Replacing the pantry thermistor sensor is typically the least expensive fix, with parts generally ranging from $15 to $50 and labor costs adding $75 to $150 if a technician is used. If the main PCB is the source of the fault, parts alone can range from $100 to $300 or more, with total repair costs potentially reaching $200 to $500 including labor.

A knowledgeable DIYer with a multimeter can begin by checking the voltage at the main PCB connector CN30-9 to CN76-1 to determine whether the circuit is open or shorted. Inspecting and reseating connectors requires no special tools and may resolve the error if a loose connection is the cause. Replacing the thermistor sensor is also a manageable repair for someone comfortable working inside a refrigerator. However, if the main PCB is at fault, that replacement is more complex and may warrant professional service.

A power reset by unplugging the refrigerator for a few minutes may temporarily clear the error display, but if the underlying sensor or wiring fault still exists, the error will return. Resetting the unit is a useful first step to confirm whether the fault is intermittent, but it is not a substitute for diagnosing and repairing the actual cause.
