LG Refrigerator Error Code Er-IK

Er-IK on an LG refrigerator signals an ice maker kit error, meaning the control board has detected a malfunction in the ice maker module located in the freezer compartment. The error typically points to a problem with the module itself or the wiring connection at the CON6 connector. Ice production will stop while this error is active, but the refrigerator's cooling functions should remain unaffected.

The Er-IK error is not a safety hazard. It indicates a malfunction limited to the ice maker system and does not affect the refrigerator or freezer's ability to maintain safe food storage temperatures. You can continue using the appliance while troubleshooting or waiting for a repair, though ice production will be suspended.

If the issue is simply a loose connector at CON6, the repair cost could be minimal, covering only a service call in the range of $75 to $150. If the ice maker module itself has failed and needs replacement, parts and labor combined typically range from $150 to $350 depending on the specific model and local labor rates. Getting a diagnostic visit to confirm the failed component before ordering parts is generally recommended.

Start by inspecting the ice maker module in the freezer for any visible damage or ice buildup, then check that the CON6 wiring connector is firmly seated. Use a multimeter to measure resistance between pins 9 and 10 of CON6; the reading should be approximately 19.7 ohms. If the connector is secure but the resistance reading is off, the ice maker module assembly will likely need to be replaced.

A reset may temporarily clear the Er-IK code, but the error will return if the underlying cause is not addressed. If the ice maker module has failed or the CON6 connection is faulty, the control board will detect the fault again once normal operation resumes. A reset is useful for confirming whether the error is intermittent, but it is not a permanent fix.
