What F1 / F3 / F9 (790-prefix, two-digit display) means

Kenmore ranges with a 790. prefix and a two-digit display come from Electrolux, and their short F codes cover three different conditions. F1 means either an oven sensor failure or a failed electronic oven control. F3 means an oven sensor failure, and F9 means a failure of the oven door lock. You will see the code on the display, and the oven may stop heating, bake at the wrong temperature, or keep the door locked after a cycle.

Common causes of F1 / F3 / F9 (790-prefix, two-digit display)

Oven temperature sensor, for F1 and F3
Electronic oven control, for F1
Door lock motor and latch switch, for F9
Wiring and connectors to each

✓ One safe check you can try

1. Read the code carefully, since F1, F3, and F9 point to different parts. 2. Cancel the cycle and let the oven cool before touching the door. 3. Unplug the range for 30 seconds, then plug it back in. 4. Try a short bake and see whether the code returns. 5. For F9, do not force the door. Wait until it is cool and the lock releases.

! Why to stop there

F1 alone cannot tell us whether the sensor or the control is the issue
We test the sensor circuit first, then the control, and test the lock for F9
We write the price down first and swap parts only with your approval

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.

F1 / F3 / F9 (790-prefix, two-digit display)F1 / F3 / F9 (790-prefix, two-digit display) questions

Which code is the lock?

F9 is the door lock failure. F1 and F3 are about temperature sensing, with F1 also covering a failed oven control. Knowing which one shows tells us where to start.

Is F1 always the control board?

No. On this 790 two-digit platform it can be the oven sensor or the control. That is why we test the sensor circuit before deciding on the board.

What helps you decide where to start?

The exact code and the model number. F9 sends us to the door lock, F3 to the sensor, and F1 to both the sensor and the control. A written price comes before any work, and we cover our workmanship for 30 days.
