KitchenAid microwave F1E6: microwave generation error
F1E6 on this built-in model means the control commanded microwave power but did not detect that microwave energy was being produced.
What F1E6 means
- Brand
- KitchenAid
- Appliance
- Built-in microwave
- Code
- F1E6
- Documented meaning
- Microwave generation error
- Applies to
- 6 KitchenAid models on 1 platform
- Can you keep using it?
- No — stop and have it checked
What the microwave is detecting
The control monitors the high-voltage section while cooking. When it runs the microwave but sees no evidence of normal power generation, it sets F1E6.
Causes listed for this condition
In the order the service documentation checks them. Documented causes come from the manufacturer's service documentation for these platforms; possible causes are based on how the system works; unconfirmed marks common assumptions that the documentation does not support.
- Possible A magnetron that is not producing microwave energy.
- Possible An inverter or high-voltage supply fault.
- Possible An open thermal protector or a wiring fault in the high-voltage section.
Safe checks you can make
- Unplug the microwave (or switch off its breaker) for one minute, then restore power and see whether the code comes back.
- Do not remove the outer cabinet or the control panel. Nothing inside a microwave is owner-serviceable.
This stage requires professional testing. Full diagnosis involves hazards such as live line voltage, gas, a sealed refrigerant system or microwave high voltage. Do not attempt it yourself.
What a technician checks
- Tests the high-voltage section and the magnetron under safe procedures.
- This requires professional testing. Every component behind the microwave's outer cabinet shares space with the high-voltage circuit, and the high-voltage capacitor can hold a lethal charge even after the unit is unplugged.
Typical repairs and cost
Depending on what diagnosis finds, this code can lead to one of these repairs:
| Repair | Typical range | Labor |
|---|---|---|
| Microwave no-heat repair (magnetron or high-voltage circuit) | $230–$520 | Moderate |
| Microwave control board replacement | $230–$520 | Moderate |
Typical total ranges for the Las Vegas area, parts and labor included. The final cost depends on diagnosis, the exact model, parts availability and whether other damage is found.
Can you keep using it?
Stop using it until it is checked. Unplug the microwave; it is not heating and the fault is in the high-voltage system.

Repair or replace?
A fault code alone rarely justifies replacing a microwave. Most F1E6 repairs involve a single component once diagnosed. Replacement becomes worth considering when the unit is near the end of its typical 8–10-year life and the diagnosed repair is a major one. See the repair-or-replace guide.
