LG Refrigerator Error Code EID — Ice Maker Sensor Failure
What this means
The EID error code on LG refrigerators indicates a failure in the freezer compartment ice maker sensor. This sensor monitors the ice maker tray temperature to determine when ice is fully frozen and ready to harvest. When the sensor fails or its wiring becomes disconnected, the ice maker cannot accurately gauge when to release ice. This code is common on LG InstaView and Craft Ice models that rely on precise temperature readings for round ice ball production. There are no user-serviceable troubleshooting steps for this error — a qualified technician must diagnose and repair the ice maker assembly or sensor.

Step-by-step fix
4 stepsPower-reset the refrigerator
Unplug the refrigerator for 5 minutes, then plug it back in. Check the display to see if the EID code clears. A temporary glitch in the sensor circuit can sometimes trigger a false alarm.
If the code returns within a few hours, the sensor or its wiring has a persistent fault.
Check the ice maker sensor wiring
Remove the ice maker assembly from the freezer compartment. Inspect the wire harness connector for the ice maker sensor — look for loose, corroded, or damaged pins. Reseat the connector firmly.
On Craft Ice models, the sensor connector is located behind the ice maker unit on the left side of the freezer wall.
Test the ice maker sensor
Using a multimeter set to ohms, disconnect and test the ice maker sensor. At room temperature (~75 °F / 24 °C), a functioning sensor should read approximately 5,000 ohms. An OL (open line) or 0-ohm reading means the sensor has failed.
If the sensor reads within spec but the error persists, the ice maker control board may be faulty.
Replace the ice maker assembly or sensor
If the sensor has failed, replace the ice maker assembly. On most LG models, the sensor is integrated into the ice maker and is not sold separately. Remove the mounting screws, disconnect the harness, and install the new assembly.
After replacement, allow 24 hours for the ice maker to begin producing ice at full capacity.
When to call a professional
LG recommends professional service for EID errors since the ice maker sensor is typically integrated into the assembly and requires precise installation. Call a technician if the code persists after a power reset.
