FCE4 and FCE5 suggest a Wi-Fi antenna or wiring fault inside the oven. Reset the breaker for a minute; if the code returns, it needs service.
Model compatibility: KitchenAid reuses codes across series and model years, so FCE4 / FCE5 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
KitchenAid lists a possible problem with the Wi-Fi antenna or its wiring.
A KitchenAid wall oven that displays FCE4 or FCE5 has a possible fault in the Wi-Fi antenna or the wiring tied to it, according to the manufacturer. That antenna handles the wireless signal used by the oven’s connected features.
Not a home-network message
The neighboring codes FCE1 to FCE3 are about the router, signal strength and time-outs, and involve your home network. These two are different. Neither article mentions the router, and the part under suspicion is inside the oven. Resetting the router is not one of the steps here.
Steps from the KitchenAid articles
Switch the oven’s circuit breaker off and wait one minute.
Switch the breaker back on.
Watch the oven for a minute and see if the code comes back.
Confirm the oven operates normally.
If the code is still there
Service is the next stage the articles give. There is no further owner step after the breaker reset.
FCE4 versus FCE5
The two numbers carry identical wording in KitchenAid’s material, and no difference between them is described.
Codes worth comparing
FCE6 and FCE9: the Wi-Fi power module, another part inside the oven
Should FCE4 or FCE5 return after the reset, our Los Angeles line is (310) 363-8964. Please have the displayed code and the oven’s model number ready, and mention that the breaker was already cycled. More on oven repair is on the service page.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
