KitchenAid Combination Oven Code F6 E7: microwave appliance manager

What F6 E7 means

Combination microwave-wall ovens such as the KOCE900HSS and KOCE507ESS can show F6 E7 when the microwave appliance manager, or the wiring tied to it, may have a problem. This concerns the upper microwave cavity. The code replaces the usual display, and the microwave section may not run. Because only the microwave side is named, the lower oven control is a separate matter and judged on its own.

Common causes of F6 E7

Microwave appliance manager failing
Wiring to the microwave appliance manager damaged

✓ One safe check you can try

1. Cancel the cycle and take any food out of the microwave. 2. Switch off the oven breaker for one minute, then on. 3. Heat a cup of water briefly to see whether the code stays away. 4. If F6 E7 returns, stop using the microwave and call us.

! Why to stop there

Microwave controls sit close to high-voltage parts.
Only testing separates the manager from its wiring.

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 E7F6 E7 questions

Is the microwave appliance manager the same as the oven control?

It is the control for the microwave cavity. F6 E7 names that manager or its wiring, so the lower oven control is a separate matter and may work normally.

Could the lower oven still work?

It may, if it displays no codes. Use it with care, and keep the microwave off until we test the microwave appliance manager and its wiring.

Why is the microwave side more cautious?

Microwave power parts hold dangerous voltage, which is why owners should only try a breaker reset and a short water test, and nothing beyond that.
