GE Refrigerator Error Code R-10- (segment f)

The R-10- (segment f) error code on a GE refrigerator indicates a fault within the pantry sensor circuit. This sensor monitors the temperature inside the pantry or fresh food drawer compartment and feeds that data back to the main PCB. The error triggers when the control board detects one of several fault conditions: physical separation of the sensor from its housing, a poor or broken electrical contact, a wiring disconnection, a short circuit in the sensor circuit, or a temperature reading that falls outside the acceptable operating range. The out-of-range threshold is defined as any reading above 149 degrees Fahrenheit or below -58 degrees Fahrenheit, both of which indicate the sensor is returning implausible data rather than a genuine compartment temperature.

The first diagnostic step is to measure the voltage at the main PCB connector CN30, specifically between pins 8 and 9. Under normal operating conditions, this voltage should fall between 1.0V and 4.5V, a range that corresponds to the sensor's valid temperature resistance output. A reading outside this window confirms an electrical fault in the sensor circuit. A voltage near 0V or a dead short points to a wiring fault or shorted sensor, while a voltage at or above the supply rail suggests an open circuit caused by a disconnection or fully failed sensor element.

Because the error encompasses both mechanical and electrical failure modes, diagnosis requires checking the sensor housing for physical separation or improper seating, inspecting the wiring harness for damage or loose connectors, and testing the sensor's resistance output against the expected voltage range at CN30. If wiring and connections check out, the pantry sensor itself is likely the failed component and will need replacement to restore normal operation.
