Display shows E1; refrigerator may run continuously or not maintain set temperatures.

Safety first: Unplug the refrigerator before removing interior panels or accessing the control board.

• Locate refrigerator thermistor: It is typically behind a small cover on the refrigerator liner wall or clipped to the evaporator cover.
• Inspect wiring: Check for pinched, cut, or corroded wires leading from the thermistor to the control board.
• Test thermistor: Disconnect the thermistor and measure resistance with a multimeter. At room temperature (~77°F/25°C), it should be around 2.7–3.5 kΩ (check tech sheet for exact spec). Infinite or near-zero resistance indicates failure.
• Replace thermistor: If faulty, remove the old sensor from its clip or housing, route the new sensor along the same path, and reconnect to the harness.
• Clear error: Restore power and verify that the E1 code clears and temperatures stabilize over the next 12–24 hours.
