LG Refrigerator Error Code 14E

The 14E code indicates an error with the ice maker freezer compartment temperature sensor. The control board has detected a temperature reading above 149°F (65°C) or below -58°F (-50°C), which falls outside any real operating condition and points to a sensor connection problem or sensor failure. The fault can involve a disconnected wire, a loose connector, a short circuit, or the sensor physically separating from its housing.

A power reset may temporarily clear the 14E code, but it will return if the underlying sensor fault has not been corrected. The control board continuously monitors the voltage on the sensor circuit, so any persistent wiring, connection, or sensor issue will retrigger the error shortly after the reset. A reset alone is not a fix, but it can be useful after completing repairs to confirm the fault has been resolved.

If the fix is simply reseating a connector or resecuring the sensor in its housing, the cost is minimal, typically just your time. A replacement ice maker temperature sensor generally runs in the range of $15 to $50 for the part. If a technician is needed for diagnosis and repair, expect labor costs in the range of $80 to $200 depending on your location and the complexity of the wiring repair involved.

Some causes of the 14E error are DIY-friendly, particularly reseating a loose connector or re-securing a sensor that has pulled out of its housing. Start by measuring voltage at main PCB connector CN90 between pins 8 and 9, which should read between 1.0V and 4.5V. If voltage is out of range and you can trace the wiring harness to identify a broken or shorted wire, that repair is also accessible to a skilled DIYer. Sensor replacement is straightforward if wiring checks pass and the sensor itself has failed.

The 14E error itself does not pose a direct safety hazard to your home or food in the main refrigerator compartment. However, the fault will typically disable the ice maker, and depending on how the control system responds, freezer temperature regulation may be affected. It is best to address the error promptly to avoid any secondary impact on food preservation in the freezer section.
