FCE6 and FCE9 are listed together: the Wi-Fi power module or its wiring.
Model compatibility: KitchenAid reuses codes across series and model years, so FCE6 / FCE9 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
Both FCE6 and FCE9 may indicate a problem with the Wi-Fi power module or the associated wiring on the range.
KitchenAid explains FCE6 and FCE9 in one line: there may be a problem with the Wi-Fi Power Module, or the associated wiring. The text matches for both codes, and nothing more is published as a diagnosis.
What a power module is
For a Wi-Fi feature, a power module is generally the part that provides what the wireless hardware needs to operate. The KitchenAid pages say no more than that, and they do not say where the part is installed in the range.
How to reset
Switch the appliance off at its circuit breaker for one minute.
Switch it on again.
Observe it for a minute to confirm the code stays away.
Verify that the range operates.
That is all the Ranges page asks of an owner, and the wall oven page says the same.
Missing from the entry
Router steps, which FCE1 through FCE3 have.
Signal advice, such as repositioning the router.
Registration guidance or a SAID number, which are specific to FCE8.
Questions
Do I look at FCE6 or FCE9 for the real fault? Use whichever your display shows, since the entries are alike.
Is my home network at fault? The entry says nothing of the kind. A part of the appliance and its wiring are the named items.
If the code returns
Having the power module and its wiring on the suspect list makes a service visit the next move. Opening the range to find either part is not advised.
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.
