LG Refrigerator Error Code Pantry Room Sensor Error

This error means the temperature sensor inside the pantry compartment is reporting a reading above 149°F (65°C) or below -58°F (-50°C), which are outside the valid operating range. In nearly all cases, the compartment is not actually at those temperatures. Instead, the thermistor sensor or its wiring circuit has failed and is sending a faulty signal to the main control board.

A reset may temporarily clear the error display, but the code will return if the underlying fault in the sensor circuit is not repaired. Resetting is useful for confirming whether the error is intermittent, but it does not fix a failed thermistor, damaged wiring, or faulty connector. Proper electrical testing is needed to identify and resolve the root cause.

If only the thermistor needs replacement, parts typically cost between $15 and $50 depending on the model, and labor for a professional repair adds $80 to $150 or more. If the main PCB is at fault, parts alone can range from $100 to $300 or higher, making that a considerably more expensive repair. Getting a diagnostic visit from a certified technician is recommended to confirm which component has failed before committing to parts costs.

A knowledgeable DIYer can start by checking the wiring connections at the main PCB connectors CN30 pin 9 and CN76 pin 1 using a multimeter to verify voltage falls between 1.0V and 4.5V. If the connectors look corroded or loose, reseating them may clear the error. Replacing the thermistor is also a manageable repair for someone comfortable with basic appliance work, but main PCB replacement should be handled by a qualified technician.

With a failed pantry sensor, the refrigerator's main control board may not be able to accurately regulate the temperature in the pantry compartment. This could result in food stored in that section being held at an unsafe temperature without you being aware of it. It is best to avoid storing perishable items in the pantry section until the sensor is repaired.
