F1E1 and F6 share one explanation: the oven could not execute a function, with the relay control board and wiring as the possible fault.
Model compatibility: KitchenAid reuses codes across series and model years, so F1E1 / F6 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
The oven could not execute the function; relay control board or wiring may be at fault.
KitchenAid’s over-the-range microwave help has one page each for F1E1 and F6, and the two read the same. The oven could not execute the function it was told to perform, and the possible problem is the relay control board or its wiring.
Relay board, in general terms
A relay board switches loads on and off when the main control calls for it. That explanation is ours and not KitchenAid’s. The company says only that the board or its wiring may be to blame, and it does not offer a home check.
First thing to try
At the breaker panel, switch the microwave’s breaker(s) off and leave them for one minute.
Switch the breaker(s) back on.
Watch the display for one minute, looking for F1E1 or F6.
Check that the microwave is working again.
When the code returns
There is no second self-check in the article. If the same code comes back, a service call is what remains on its list.
Details to give the technician
Which code appeared, F1E1 or F6.
Whether it came up as you pressed a function key or by itself.
That you already did the one-minute breaker reset.
The article attaches no cooking symptom to either code.
Codes that sound alike
F9: the same “could not execute” line, but it blames the appliance control board along with the relay control board
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.
