Frigidaire Range Error Code F110

F110 indicates that the NIU (Network Interface Unit) serialization process failed. This means the network module was not properly assigned its unique MAC address, which is required for the range to connect to and be recognized on a home network. This failure originates during manufacturing rather than from user-side settings or configuration. The error signals that the NIU's network identity is incomplete or missing.

F110 is specific to the network interface unit and does not affect the core cooking functions of the range, such as the burners or oven. The appliance should remain safe to use for normal cooking. However, any smart home connectivity or app-based features will not function until the NIU issue is resolved.

Repair costs will vary depending on labor rates in your area and the cost of the NIU replacement part. In general, you can expect to pay somewhere in the range of $150 to $400 or more for a service call plus parts, depending on the specific model and technician pricing. If the range is still under warranty, the repair may be covered, so checking your warranty status is a good first step.

The first step is to check whether the range can connect to your network and whether its MAC address appears on the network. If the MAC address is not visible, the NIU module itself is the source of the problem. Because F110 is a serialization failure rooted in the hardware module, resolving it typically requires replacing the NIU, which is best performed by a qualified technician.

A basic power reset is unlikely to clear F110 because the error reflects a serialization failure in the NIU hardware, not a temporary software glitch. Since the MAC address was never properly written to the module, cycling power will not restore the missing network identity. The underlying hardware issue must be addressed for the code to clear.
