KitchenAid microwave F6EA: user interface over-temperature
F6EA on this built-in model means the control sensed that the user interface electronics were getting too hot.

- With caution
What the microwave is detecting
The interface board has its own temperature protection. When it runs too hot, the control reports F6EA.
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 Heat building up around the controls, for example from blocked vents or long high-temperature cooking in an adjacent oven.
- Possible A cooling fan that is not running properly.
- Possible A faulty interface temperature sensor that reports false heat.
Safe checks you can make
- Make sure the vents around the control area are clear.
- Let the unit cool with the power off, then try again.
- 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
- Checks the cooling fan and airflow, then the interface board.
- 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 control board replacement | $230–$520 | Moderate |
| Microwave touchpad replacement | $200–$460 | Light |
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?
Use with caution. Let it cool. If the code keeps returning, stop using it and have the cooling system checked.

Repair or replace?
A fault code alone rarely justifies replacing a microwave. Most F6EA 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.
