GE Range Error Code F109

F109 on a GE range means that an over-the-air software update attempt failed. The range's Network Interface Unit (NIU) tried to download and install an update over your home Wi-Fi network but could not complete the process. This is most often caused by a network connectivity issue rather than a problem with the range hardware itself.

A power-cycle reset can clear a temporary F109 condition, especially if the failure was caused by a one-time glitch in the NIU or a brief network interruption. However, if the underlying cause, such as a weak Wi-Fi signal or invalid network credentials, has not been corrected, the code is likely to return when the range attempts the update again.

If the issue is purely a network or connectivity problem, there is no parts cost involved. If the NIU hardware is determined to be defective and requires replacement, parts and labor costs can vary, but repairs of this type typically fall in the range of $150 to $350 depending on the specific model and local labor rates.

Start by confirming that your home Wi-Fi network is active and has a working internet connection. If the network is fine, power-cycle the range by turning off its circuit breaker for 30 seconds, then restore power and allow the range to retry the update. If the error returns, reconnect the range to your Wi-Fi network through its settings menu to make sure the stored credentials are current.

No, the F109 code is not a safety-related error. It only indicates that a software update could not be delivered over the network and does not affect the cooking or heating functions of the range. You can continue to use the range normally while troubleshooting the network issue.
