KitchenAid Wall Oven Code F3 E2: main temperature sensor, control or wiring

What F3 E2 means

F3 E2 on KitchenAid electric single, double and combination wall ovens like the KOCE500ESS says the oven temperature sensor, the control, or the associated wiring may have a problem. Unlike E0 and E1, no cavity is named, so it applies to the oven's main temperature sensing. The oven may heat unevenly or shut off early. Here it is the oven's main temperature sensing that the control is unhappy about.

Common causes of F3 E2

Oven temperature sensor failing
Control misreading the sensor
Sensor wiring or connector damaged

✓ One safe check you can try

1. Let the oven cool. 2. Press Cancel. 3. Cycle the breaker off for a minute. 4. Run a bake at 350 F with an oven thermometer if you have one, and note whether the numbers match. If F3 E2 returns, stop and call.

! Why to stop there

Sensor readings are meter-only.
Wiring runs behind insulation.
We bring common sensors.

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.

F3 E2F3 E2 questions

Is F3 E2 the same as F3 E3?

The published meanings match, so both point to the sensor, control and wiring. We diagnose them the same way. Both entries state the same sensor, control and wiring meaning, so the same tests apply to each.

Can the oven be used?

If it still heats, temperatures may be unreliable. Use a separate thermometer or hold off. A separate thermometer shows whether the oven is accurate. If it is not, hold off until it is repaired.

What will it cost?

You see a written price before we start. A correct fix often needs just the sensor, though we confirm that with a test and tell you before any work begins.
