KitchenAid Wall Oven Code F6: the main oven control or its wiring

What F6 means

On KitchenAid electric single, double and combination wall ovens such as the KOSE500ESS or KODE500ESS, a plain F6 points to the oven control, or the wiring connected to it. The electronics that run the oven are reporting a problem. You will see the code instead of the clock, and keys, heating or timers may stop responding. Because the control is the brain of the oven, this is one of the codes where a technician's measurements matter more than a quick fix.

Common causes of F6

Oven control electronics failing
Wiring or connector problem at the control

✓ One safe check you can try

1. Press Cancel and wait for the oven to cool. 2. Turn the oven's breaker off for a full minute, then on. 3. See whether the clock returns and a short bake starts. 4. If F6 appears again, leave the oven off and call us. Do not remove the control panel.

! Why to stop there

Control electronics run on the oven's household supply and are not an owner repair.
A reset may only hide a control that is failing.
We quote in writing first, and our repair comes with 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.

F6F6 questions

Is plain F6 the same as F6 E1?

No. A plain F6 names the oven control and wiring. Codes with a second character, such as F6 E1, point to the appliance manager, the converter control or other specific parts.

Can the control reset itself?

Sometimes a power interruption leaves a one-time code that a breaker reset clears. If F6 returns on its own, the control needs testing, and we can do that on site.

Will the oven bake while F6 shows?

Do not expect it to. The oven control is what decides when to heat, so cancel and call us instead of trying repeated starts, which only add wear.
