KitchenAid Combination Oven Code F6 E8: the microwave manager control

What F6 E8 means

On KitchenAid combination microwave-wall ovens such as the KOCE500ESS or KOCE900HSS, F6 E8 means the microwave appliance manager control, or the associated wiring, may have a problem. The upper microwave cavity is affected. You will see the code on the display, and the microwave may not respond to a start command. Because it is the microwave side, it is best left alone until a technician tests the control and its wiring.

Common causes of F6 E8

Microwave appliance manager control not responding
Wiring or connector problem to that control

✓ One safe check you can try

1. Press Cancel and empty the microwave cavity. 2. Cut power at the breaker for about a minute, then switch it back on. 3. Try a short run with a cup of water. 4. If F6 E8 comes back, leave the microwave unused and call us.

! Why to stop there

The control cannot be tested without opening the oven.
A reset that only works for a day points to a real control problem.
You approve a written price before work, and the repair includes a 30-day workmanship warranty.

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.

F6 E8F6 E8 questions

How is F6 E8 different from F6 E7?

Both concern the microwave appliance manager and its wiring. We test the same control for either code and report what we find, with a written quote before work.

Will the oven's clock still work?

It may, since the code is about the microwave cavity's control. Do not assume the whole oven is safe to run, and report any other codes to us.

What should I tell you when I call?

The exact code, the model number, and whether it appears at once or only when you start the microwave. That helps us plan the visit and bring the right parts.
