GE Refrigerator Error Code F71

The F71 error code on a GE refrigerator indicates that the control board is not detecting any pulse signals from the flow meter during a water dispense cycle. The flow meter is a small sensor, typically positioned along the water supply line inside the refrigerator, that generates electrical pulses as water passes through it. Each pulse corresponds to a measured volume of water, allowing the control system to track dispense quantity and confirm that water is actually flowing. When the control board initiates a dispense but receives zero pulses from the flow meter, it logs the F71 fault to indicate the sensor signal is absent.

This fault can originate from several points in the system. The flow meter itself may have failed internally, with a broken or stuck impeller that no longer spins as water passes through. The wiring harness connecting the flow meter to the control board is another common failure point, as damaged insulation, corroded terminals, or a loose connector can interrupt the signal path entirely. In some cases, the water supply to the meter may be obstructed, meaning the impeller never spins because no water is reaching it, which points toward a frozen fill line, a closed supply valve, or a failed water inlet valve.

The control board itself can also be at fault if it is not sending power to the flow meter circuit or is unable to read the incoming pulse signal correctly. Diagnosing F71 generally requires checking for water supply continuity first, then verifying wiring harness integrity, and finally testing the flow meter for proper operation. Resistance and voltage specifications for the flow meter circuit should be confirmed against the wiring diagram specific to the model before replacing components.
