Four codes, one named suspect: KitchenAid points F1E4, F6E0, F7 and E13 at the appliance control board and its wiring.
Model compatibility: KitchenAid reuses codes across series and model years, so F1E4 / F6E0 / F7 / E13 … 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 or did not pre-heat correctly; appliance control board or wiring may be at fault.
Four KitchenAid over-the-range microwave codes, F1E4, F6E0, F7 and E13, share a suspect in the help pages: the appliance control board, or the wiring that serves it.
Wording for each code
F1E4: the oven could not execute the function.
F6E0: the oven could not execute the function.
F7: the oven could not execute the function.
E13: the oven did not pre-heat correctly.
E13 speaks about preheating where the other three use the general “could not execute” sentence. Every one of them leads to the control board and its wiring.
Reset
Switch the breaker(s) for the microwave off.
After one minute, switch them on.
Spend a minute watching the unit for the code to repeat.
Use the microwave normally to test it.
One board, several numbers
The pages give no reason for four numbers pointing at one part. What can be said: the board is the common point. Record the exact code, as E13 is about preheat and the others are not.
After the reset
Nothing beyond scheduling service is listed. A code that repeats calls 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.
