LG Refrigerator Error Code ICE-Sensor

The ICE-Sensor code means the ice maker temperature sensor (thermistor) has failed or is sending a signal the control board cannot interpret as valid. The refrigerator uses this sensor to monitor ice maker compartment temperature and regulate the ice production cycle. When the sensor reading falls outside the acceptable resistance range, the board logs this fault. Ice maker operation is typically suspended until the issue is resolved.

The ICE-Sensor error is not a safety hazard to your household. It is a functional fault that affects ice production only. Your refrigerator and freezer compartments will continue cooling normally. The main concern is that the ice maker will stop producing ice until the sensor issue is corrected.

Repair cost depends on the failed component. An ice maker thermistor sensor part typically costs in the range of $15 to $60 for the part alone. If professional labor is required, total repair costs including diagnosis and installation generally range from $100 to $250 depending on your location and service provider. Control board replacement, if needed, will cost more.

A reset may temporarily clear the code, but it will return if the underlying sensor fault is still present. The control board continuously monitors the thermistor resistance, so any persistent open circuit, short, or out-of-range reading will trigger the error again. A reset is useful for confirming whether the fault is intermittent, but it is not a repair.

Start by disconnecting connector CON10 and measuring resistance between pins 1 and 2 using a multimeter. A correct reading falls between 1.4 kΩ and 120 kΩ. If the reading is open or shorted, the thermistor or its wiring needs replacement. If the reading is within range, inspect the wiring harness and CON10 connector for damage or corrosion before suspecting the main control board.
