GE Refrigerator Error Code F99

The F99 code means the French Door icemaker became stuck in Harvest Fix Mode and could not recover within 30 minutes. Harvest Fix Mode is a corrective routine the icemaker control activates when a normal harvest cycle stalls. When that recovery attempt also fails, the F99 fault is recorded. A component such as the harvest heater, ejector motor, or thermistor is typically responsible.

The F99 fault is not a safety hazard in the traditional sense. The refrigerator and freezer compartments will continue to cool normally. The primary impact is that the icemaker will not produce ice until the fault is resolved. You can continue using the refrigerator while arranging for a repair.

A power cycle or icemaker reset may temporarily clear the F99 code and allow the icemaker to attempt operation again. However, if the component causing the stalled harvest cycle has not been repaired or replaced, the fault will return. A reset is a useful first step to confirm whether the issue is intermittent, but it is not a permanent fix when a hardware failure is present.

Some cases of F99 can be resolved by a knowledgeable DIYer, particularly if the cause is visible ice buildup or a jammed ejector arm that can be cleared manually. However, diagnosing a failed harvest heater, thermistor, or ejector motor requires a multimeter and familiarity with icemaker components. If you are not comfortable working with refrigerator electronics and wiring, a qualified appliance technician is the safer option.

Repair costs depend on which component has failed. A harvest heater or thermistor replacement is generally less expensive, with parts and labor typically ranging from around $100 to $250. An ejector motor or icemaker assembly replacement can range from approximately $150 to $400 or more depending on parts pricing and local labor rates. Getting a diagnostic service call first will give you an accurate estimate.
