LG Refrigerator Error Code R-1016

R-1016 indicates an Ice Pipe Heater open circuit error. The refrigerator's main control board detected that the heater responsible for keeping the ice maker water fill tube clear of ice is not completing its electrical circuit. This is most often caused by a loose harness connector, a contact issue at the connector pins, or a broken wire rather than a failed heater element.

A power reset may temporarily clear the error code from the display, but if the underlying wiring fault or failed heater element is still present, the code will return. The open circuit condition must be physically repaired before the error will clear permanently.

If the fix is simply reseating a loose connector, labor costs for a service call typically range from around 75 to 150 dollars depending on your area. If the ice pipe heater element needs replacement, expect to add the cost of the part, which generally falls in the range of 20 to 60 dollars, plus any additional labor time for accessing and replacing the component.

A knowledgeable DIYer can start by locating connector CN79 on the main PCB and checking whether the heater harness has slipped loose, then reseating it firmly. You should also inspect the Blue and White wires along their entire length for any visible damage. Using a multimeter to confirm resistance of approximately 72 ohms between the two wires will tell you whether the heater element itself has failed and needs replacement.

This error is not a safety emergency. It means the ice maker water tube may be at risk of freezing and blocking, which would stop ice production, but it does not affect the refrigerator's core cooling function. You can continue to use the refrigerator for food storage while scheduling a repair.
