LG Error Code Er IS
Ice maker sensor error
Common Causes
- 1Sensor malfunction
Step-by-Step Troubleshooting
- 1
Access the ice maker module by removing the ice bin and the ice maker mounting screws
- 2
Locate the ice maker optical sensor (or mechanical arm sensor depending on model) that detects ice bin fullness
- 3
Clean the optical sensor lenses with a dry cloth — frost film on the sensor eye is a common cause of false triggers on LG Craft Ice models
- 4
Check the ice maker tray heater that releases ice cubes — if the heater is weak, cubes jam and the sensor reads a perpetual full state
- 5
Run the ice maker test cycle by pressing and holding the TEST button on the ice maker module for 3 seconds
Pro Diagnostic Tip
LG Craft Ice makers have a separate sensor circuit from the standard ice maker. If the Er IS code shows only after activating Craft Ice mode, the issue is isolated to the slow-ice sphere mold sensor rather than the main ice maker.
