KitchenAid Over-the-Range Microwave Code F6E0: Main appliance control board

What F6E0 means

On KitchenAid over-the-range microwave hood combinations such as the KMHS120ESS or KMHC319ESS, F6E0 signals a possible problem with the appliance control board or the wiring tied to it. The board is the main brain of the microwave. With F6E0 showing, buttons may stop responding and heating is blocked. The keypad may still beep or light up, yet the unit will not respond to commands or start a cycle, which is the usual way this code shows itself.

Common causes of F6E0

Appliance control board that has stopped working correctly
Loose or damaged wiring between the control board and other parts

✓ One safe check you can try

1. Press Cancel and see whether keys respond. 2. Unplug the microwave or turn the breaker off for a full minute and reconnect. 3. Try a quick cycle with a cup of water. 4. If F6E0 returns, stop using the microwave and call for service.

! Why to stop there

The control board is the most expensive electronic part in the unit, so it should be diagnosed, not guessed.
Taking the microwave off the wall bracket to reach the board is awkward and unsafe alone.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.
