F1E6 refers to the microwave thermistor or sensor or its wiring, and KitchenAid mentions help from a technician.
Model compatibility: KitchenAid reuses codes across series and model years, so F1E6 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 microwave thermistor or sensor, or the wiring, may have a problem.
F1E6 in one paragraph
If your KitchenAid wall oven has a microwave and the display shows F1E6, the Microwave Thermistor or Sensor, or the associated wiring, may have a problem.
Thermistor basics
A thermistor is a small component whose resistance shifts as the temperature shifts, which is how a control can read a temperature. This one belongs to the microwave section. Neither the temperature it reads nor its position is described by KitchenAid.
KitchenAid’s reset
Switch the oven’s breaker off.
One minute later, switch it on.
Remain near the oven for a minute and look for F1E6.
Try the oven to be sure it operates.
Where the article mentions a technician
Unlike most entries, this one adds a direct line. You may need help from a qualified technician, and a pointer to scheduling an appointment follows. That applies when the reset does not hold. No thermistor test values are given, and owners are not told how to reach or check the part.
Limits of the entry
There are no described symptoms, such as the microwave not heating, so the display is the only evidence you have.
It is not the sensor that reads the main oven cavity. Oven temperature sensor codes form a separate group, and mixing them up would send you in the wrong direction.
