KitchenAid Double Wall Oven Code F3 E1: lower oven temperature sensor

What F3 E1 means

F3 E1 is the lower-cavity partner of F3 E0 on KitchenAid electric double and combination wall ovens such as the KOSE507ESS. The lower oven temperature sensor, the control, or the associated wiring may have a problem. The lower oven may not preheat or hold temperature, while the upper cavity may keep working as normal. Check whether the upper cavity bakes properly while you wait for the visit.

Common causes of F3 E1

Lower oven temperature sensor reading wrong
Control not handling the lower sensor signal
Wiring to the lower sensor loose

✓ One safe check you can try

1. Allow the lower oven to cool. 2. Press Cancel and watch the display. 3. Turn off the breaker for one minute and restore it. 4. Bake in the upper oven if it works, and avoid the lower one if F3 E1 returns.

! Why to stop there

The lower sensor is hidden in the cavity wall.
Meter tests tell sensor from control.
Mistakes can lead to a second visit.

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.
