FCE1, FCE2 and FCE3 are Wi-Fi connection codes, not heating faults. Reset the router and the oven's power.
Model compatibility: KitchenAid reuses codes across series and model years, so FCE1 / FCE2 / FCE3 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
Appliance could not connect to the router (timeout, weak signal, router, Wi-Fi module or wiring).
A Wi-Fi code
FCE1, FCE2 and FCE3 on a Wi-Fi-equipped KitchenAid oven concern the wireless link, not heating. KitchenAid’s wording is that the appliance failed to reach the router.
Possible sources
the connection timing out
a weak signal
the router going bad
the oven’s own Wi-Fi module
wiring
You can check signal strength and the router at home, so begin with those.
Working through it
Cycle the oven’s breaker with a minute off, watch for a minute after restoring it, and check the oven operates.
Restart your wireless router.
Test another Wi-Fi device; the article recommends bringing a phone or tablet to the spot where the oven is installed.
When that device is fine: router unplugged for 2 minutes then plugged in, followed by the oven’s power disconnected for 2 minutes then reconnected.
Signal not strong
If the bars are not full, the article gives three options. Move the router to another place in the house, add an extender that is compatible, or get in touch with your internet provider.
Calling for a technician
After the router and the oven have both been reset, a persisting code leaves only the Wi-Fi module and the wiring on the list, and those are for a technician.
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.
