Step-by-Step DIY Fix Guide
- SAFETY: Unplug the refrigerator before accessing the ice maker compartment.
- Reset the refrigerator by unplugging for 5 minutes, then restore power and check if EID clears.
- If EID returns, remove the ice maker by unscrewing the mounting screws and pulling it forward to access the wiring harness.
- Check the sensor connector — disconnect and reconnect to ensure a firm connection.
- If EID persists after reconnecting the sensor harness, the thermistor or ice maker assembly needs professional replacement.
If the warning comes back after restart
- If airflow still seems weak after the basic checks, the fan path or a deeper obstruction becomes more likely.
- If the warning returns immediately after a clean restart, the sensor or wiring path becomes more likely than a one-time glitch.
- EID persists after a power reset and reconnecting the sensor harness
What This Error Means
Error EID on your LG refrigerator means: The temperature sensor inside the freezer ice maker has failed or is reading outside the expected range. The refrigerator cannot monitor the ice maker tray temperature and has disabled ice production to prevent a malfunction. The refrigerator's self-diagnostic system has detected this condition.
The most frequent cause is ice maker thermistor has failed — resistance value is open or shorted. Work through the causes and fix steps below in order — many LG refrigerator errors are resolved without a service call.
Many cases of EID can be resolved by the homeowner. The steps below cover the full DIY checks — if they do not resolve the error, a technician is needed.
Sensor faults require professional diagnosis. A 5-minute power reset resolves transient communication glitches. If the code returns after a reset, the sensor or its wiring has physically failed and will not recover without replacement.
Most Likely Cause by Symptom
The LG refrigerator may stop, pause, or refuse to complete the cycle normally.
Likely cause: Ice maker thermistor has failed — resistance value is open or shorted
Check first: SAFETY: Unplug the refrigerator before accessing the ice maker compartment.
The warning may return immediately because the appliance is detecting an internal fault.
Likely cause: Wiring harness connector to the ice maker sensor has become loose or corroded
Check first: Reset the refrigerator by unplugging for 5 minutes, then restore power and check if EID clears.
Common Causes
- Ice maker thermistor has failed — resistance value is open or shorted
- Wiring harness connector to the ice maker sensor has become loose or corroded
- Ice build-up around the sensor causing a false reading
- Control board fault affecting the sensor input circuit
What Not to Do
- Do not continue operating the ice maker with EID active — running without valid temperature data can cause the tray heater to malfunction
Model and Display Variation Notes
Model-family notes
- LG refrigerator display wording and code formats can vary by series.
- If your model behaves differently, check the owner manual before trying any deeper maintenance step.
Display and panel differences
- Panel wording can vary by series, so confirm the exact code pattern before buying parts.
Parts, Tools and Service Options
Common parts
- Ice maker assembly if thermistor is integrated into the unit ($60–$150)
- Ice maker thermistor if sold separately for your model ($15–$40)
Manual and model check
Check your exact model and manual before ordering any LG refrigerator parts.
Service option
LG service visit if the warning returns after the basic checks are complete.

When Not to Keep Troubleshooting
EID persists after a power reset and reconnecting the sensor harness
How to Prevent It Recurring
- Inspect the ice maker wiring harness annually — the connector can loosen from vibration over time
Related Error Codes
EIU
The ice maker assembly has reported a general internal fault. The unit is not functioning correctly and ice production has stopped.
iT
The ice maker has reported a general internal defect. The refrigerator's diagnostics have identified a fault within the ice maker mechanism that is outside the scope of a simple sensor or fan error.
IF
LG refrigerator error IF usually means the ice maker compartment fan is not running normally.
