How to fix LG er-is — step by step
Work through these in order, from simplest and safest first. Stop as soon as the code clears.
- Power reset the fridge
Unplug the fridge for 10 minutes, then plug it back in to clear a temporary sensor fault. - Clear jammed ice
Remove the ice bin and clear any jammed cubes around the ice maker. A jam can strain the sensor and mechanism. - Check the ice maker power switch
Make sure the ice maker is switched on. Then run a manual defrost of the compartment if ice has built up around the sensor.Safety warning: Do not force the ejector arms or tray.
When to call a technician
- The code returns after a reset
- The ice maker is completely dead
- The ice maker overfills with water
- The code appears on a brand-new ice maker
Frequently asked questions
Is Er IS the same as Er IT?
No. Er IS means the ice maker sensor is bad. Er IT means the ice maker mechanism itself reported a system error.
Can a jammed cube really cause this?
Yes. A stuck cube can hold the mechanism mid-cycle, and the sensor readings go out of range.
Do I need a whole new ice maker?
Not always. If the sensor alone failed, only it needs replacing. A technician can test which part is bad.
