LG Refrigerator Error Code R-11

R-11 is an ice maker sensor error code on LG refrigerators. It means the main control board is receiving a signal from the ice maker temperature sensor that is either out of the acceptable voltage range or completely absent. This can be caused by a dislodged sensor, damaged wiring, a short circuit, or a failed sensor that is reading temperatures above 149°F (65°C) or below -58°F (-50°C).

A reset may temporarily clear the R-11 code from the display, but the fault will return if the underlying problem has not been resolved. Resetting is useful to confirm whether a fault is persistent or intermittent, but it should not be treated as a fix. The sensor circuit should be tested and the root cause corrected before relying on the ice maker again.

Repair costs vary depending on the cause. If only a connector needs to be reseated or the sensor repositioned, there may be no parts cost at all. An ice maker temperature sensor part typically falls in the range of $20 to $60 depending on the model. If a technician is needed, expect labor costs to add $80 to $150 or more on top of any parts, though prices vary by region and service provider.

Some causes of R-11 are DIY-friendly. If the sensor has simply slipped out of its housing, reseating it may clear the fault without any parts needed. Similarly, reseating the connector at CN90 on the main PCB costs nothing and should be tried early. However, replacing a faulty sensor or repairing damaged wiring requires basic electrical knowledge and comfort working inside the refrigerator, so some homeowners prefer to call a technician for those repairs.

The R-11 error itself does not pose a direct safety hazard to your household. It is specific to the ice maker sensor circuit and does not affect the main fresh food or freezer cooling systems. However, leaving the fault unaddressed means the ice maker will likely not operate correctly, and in some cases ice production will stop entirely.
