GE Refrigerator Error Code F108

F108 indicates the freezer icemaker has entered Fault Mode after experiencing a Harvest Fault. The harvest cycle is the process of releasing formed ice cubes from the mold, and when that process fails repeatedly, the icemaker shuts down and displays F108. The icemaker will not produce ice again until the underlying cause is identified and corrected.

Resetting the icemaker may temporarily clear the F108 fault code, but the code will almost certainly return if the root cause has not been fixed. Because F108 is triggered after a repeated harvest failure, the icemaker will attempt another harvest cycle after a reset and fail again if the defective component is still in place. Always diagnose and repair the underlying issue before relying on a reset.

Repair costs vary depending on the failed component. A replacement harvest heater or thermistor typically falls in the range of $15 to $60 for parts, while a full icemaker module or assembly can range from $50 to $150 or more. If you hire a technician, expect to add a service call fee and labor costs, which can bring the total repair to somewhere between $100 and $300 depending on your location and the parts needed.

Some causes of F108 are DIY-friendly, such as clearing an ice jam from the ejector mechanism or checking the water supply line for kinks. However, replacing components like the harvest heater, thermistor, or icemaker module requires basic electrical testing skills and comfort working with appliance wiring. If you are not experienced with appliance repair, a qualified technician is recommended for component-level diagnosis.

F108 is not a safety hazard in the traditional sense. It does not indicate a gas leak, electrical short, or fire risk. The fault simply means the icemaker has disabled itself to prevent repeated failed cycles. Your refrigerator and freezer will continue to cool normally, but ice production will be stopped until the fault is resolved.
