GE Refrigerator Error Code F103

The F103 error code on a GE refrigerator indicates that the freezer compartment icemaker's feeler arm sensor is continuously reporting that the ice bucket is full, even after a completed dispense cycle. Specifically, the control board expects the full-bucket signal to clear within 30 seconds following a crushed ice dispense or 15 seconds following a cube ice dispense. If the sensor still reads full after those windows have elapsed, the board flags F103 and halts normal icemaker operation to prevent motor overload or mechanical damage.

The feeler arm sensor is a mechanical or electromechanical component that physically contacts the ice level in the bucket to determine when production should pause. When ice is successfully dispensed, the ice level drops, the arm should lower, and the sensor signal should shift from full to empty. If this transition does not happen within the defined timing window, it points to a fault somewhere in the sensing or dispensing pathway. Common failure points include a stuck or frozen feeler arm that cannot pivot freely, a failed sensor that sends a constant full signal regardless of arm position, or a wiring issue between the sensor and the control board.

It is also worth considering whether the dispense mechanism itself is underperforming. If ice is not actually being moved out of the bucket during a dispense cycle, the ice level remains high and the feeler arm never drops, which would logically trigger F103 even if the sensor itself is functioning correctly. A jammed auger motor, frozen ice clumps bridging inside the bucket, or a failed dispenser actuator can all produce this scenario. Isolating whether the sensor or the dispense mechanism is at fault is the key first step in diagnosing this code.
