Error Codes (undefined): Troubleshooting, Fixes & Prevention Tips explained below.

What Does Freezer Sensor Fault Mean?❓

If your LG refrigerator shows a Freezer Sensor Fault, it means the sensor that checks the temperature inside the freezer isn’t working right. This sensor helps control how cold your freezer gets. If it breaks or disconnects, the freezer might stop cooling properly or overfreeze.

refrigerator - What Causes Freezer Sensor Fault?

  • The sensor wire is loose or unplugged
  • The freezer sensor itself is faulty or shorted
  • There is corrosion or damage on the sensor terminal
  • Moisture or frost is interfering with sensor readings
  • The control board (PCB) is failing to read sensor input

refrigerator - Common Fixes for Freezer Sensor Fault❓

  • Turn Off the Fridge

    1. Unplug it from the power outlet or switch off the breaker.
    2. Wait for 5–10 minutes before plugging it back in to reset the system.

  • Check the Freezer Sensor Connection

    1. Open the back panel inside the freezer section.
    2. Make sure the sensor is properly connected to the wire harness and PCB board.

  • Look for Damage or Ice Build-Up

    1. Inspect the sensor for signs of corrosion, burnt marks, or disconnected wires.
    2. Check if frost or ice has covered the sensor which can block accurate readings.

  • Replace the Sensor (if needed)

    1. Buy a freezer sensor compatible with your LG refrigerator model.
    2. Install it securely in place and connect it to the original wiring.

  • Call a Technician

    1. If the error doesn't clear or cooling doesn't return call LG support or a certified fridge technician.
    2. They can test the sensor and control board professionally.
