GE Refrigerator Error Code F115

F115 means the refrigerator's control board is not detecting a feedback signal from the odor filter fan while it is commanded to run. The control monitors the fan's operation through a signal from the motor, and if that signal is missing, the fault code is triggered. This indicates the fan may not be spinning due to a wiring issue, a motor failure, or a physical obstruction.

The F115 fault relates specifically to the odor filter fan, which handles air filtration rather than cooling. Your refrigerator's primary cooling and freezer functions are likely unaffected in the short term. However, it is still advisable to address the fault promptly, as an inoperative fan can affect air quality inside the fresh food compartment and the underlying issue could indicate a broader electrical problem.

Repair costs depend on the cause. If only a connector needs reseating or a wiring repair is made, costs can be minimal. An odor filter fan motor replacement typically runs in the range of $30 to $80 for the part, plus labor if a technician is involved. A control board replacement, if needed, can range from $150 to $350 or more for parts alone. A service call for diagnosis generally costs between $75 and $150 depending on your location.

Some causes of F115 are DIY-friendly, such as reseating a loose connector, clearing an ice obstruction from the fan, or inspecting the wiring harness for visible damage. If the fan motor itself has failed, replacing it is a moderate-difficulty repair that requires accessing the odor filter fan assembly and disconnecting the harness. Control board replacement is more complex and is generally better handled by a qualified technician.

A reset may temporarily clear the F115 code from the display, but the fault will return if the underlying problem has not been corrected. The control board will detect the missing fan feedback the next time it commands the fan to run and log the error again. A permanent resolution requires diagnosing and repairing the root cause, whether that is a connection issue, a failed motor, or an obstruction.
