JennAir Double Wall Oven Code F3 E5: lower oven temperature sensor

What F3 E5 means

On JennAir double wall ovens such as the JJW9830DDP, F3 E5 means there may be a problem with the lower oven temperature sensor, the control, or the wiring. The lower cavity depends on its own sensor to hold temperature. You will see F3 E5 on the display, and the lower oven may not heat or may hold the wrong temperature.

Common causes of F3 E5

Lower oven temperature sensor that has gone out of range
Sensor lead or connector in the lower cavity that is damaged
Control misreading the lower sensor signal

✓ One safe check you can try

1. Press Cancel and let the lower oven cool completely. 2. Try the upper oven alone to see whether it works. 3. Flip the breaker off for one full minute, then back on, which clears a stuck lower oven sensor signal. 4. Run a short bake in the lower oven. 5. Still seeing F3 E5? Stop here and call for service on the lower oven sensor.

! Why to stop there

Only the lower cavity is involved, so we test that circuit rather than the whole oven.
The sensor lead is fragile and easy to bend into a short.
A guess at the board could leave a bad sensor unrepaired.

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 E5F3 E5 questions

Can I use the upper oven while F3 E5 shows?

The code concerns the lower cavity. The upper oven may keep working, though we recommend a check so the problem does not spread. The upper oven runs on its own sensor, so it is not part of this alert.

What does the E5 mean here?

It identifies the lower oven sensor check that failed. JennAir lists the same cause for a few neighboring numbers, so we read the full code.

How much will the sensor repair cost?

We cannot say until we test it, but you see a written price before any part is ordered. Our work includes a 30-day workmanship warranty.
