LG refrigerator with error code E Id

As an expert technician, I have diagnosed the LG refrigerator with error code E Id Craft Ice Maker Sensor Error.

LG refrigerator with error code E Id

Error Explanation

The E Id error code indicates a malfunction within the temperature sensor (thermistor) circuit of the Craft Ice Maker (the unit located in the freezer drawer that produces spherical ice). The main control board has detected that the sensor signal is either missing, shorted, or out of the acceptable range. Because the refrigerator cannot determine the temperature of the ice mold, it will disable the Craft Ice Maker to prevent mechanical damage or flooding.

LG refrigerator with error code E Id: Troubleshooting Instructions

  1. Hard Reset: Disconnect the refrigerator from the power outlet for at least 5 minutes. This allows the capacitors on the Main Control Board to discharge and may clear a temporary software glitch.
  2. Inspect the Wire Harness: Open the freezer drawer and locate the wiring connector for the Craft Ice Maker at the top of the compartment. Ensure the plug is fully seated and that no wires are pinched, frayed, or broken.
  3. Manual Test Cycle: Locate the small Test Button on the side or bottom of the Craft Ice Maker assembly. Press and hold it for 3 seconds. The unit should begin a harvest rotation. If the unit moves but the error returns, the internal sensor is defective.
  4. Check for Ice Obstructions: Ensure no ice cubes are jammed in the mold or the ejector mechanism, as physical resistance can sometimes trigger sensor-related communication errors.
  5. Resistance Testing: If you have a multimeter, you can test the thermistor at the wire harness connector (typically the two white wires, though colors may vary by specific sub-model).

Expected Ohmic/Resistance Values

The Craft Ice Maker Sensor is an NTC (Negative Temperature Coefficient) thermistor. Its resistance changes based on the temperature:

  • At 77°F (25°C): Approximately 10k Ω
  • At 32°F (0°C): Approximately 30k Ω
  • At 0°F (-18°C): Approximately 77k Ω
  • Open Circuit (0 Ω or ∞): Indicates a failed sensor that requires replacement.

Estimated Repair Cost

  • Replacement Part: $160 – $260 USD.
    (Note: LG typically does not sell the sensor individually for the Craft Ice Maker; the entire Craft Ice Maker Assembly must usually be replaced.)

Safety Warnings

Warning: Always disconnect the refrigerator from the power source before inspecting wiring or removing components. Failure to do so can result in severe electric shock.
Warning: When handling the Craft Ice Maker, be aware that the heater under the mold may be hot if the unit was recently in a harvest cycle.

Repair Difficulty

DIY (Moderate): This repair is manageable for most homeowners. It involves removing a few screws to drop the Craft Ice Maker assembly from the freezer ceiling and unplugging a single wire harness. No complex calibration is required after installation.
