Kenmore Oven F09 Error Code
Oven exceeds maximum temperature
What this error means
F09 is a safety over-temperature fault. The ERC detected oven temperature above the safe limit—often from a welded relay or failed sensor reading low.
How F09 is detected
Kenmore oven models lock the door or lid before energizing fill, heat, or high-speed spin. F09 means the latch switch never sent a "locked" signal to the main control, or the lock motor did not complete its travel. On Kenmore Elite 790.75903, Kenmore 790.46187300, and similar variants, clothing caught in the gasket, a misaligned strike, or a failed latch assembly are the most common mechanical causes—not the board itself.
Inspect the door gasket perimeter and strike alignment before replacing the latch. Bake relay stuck closed on the ERC is reported frequently on this code. After correcting mechanical issues, turn off the breaker immediately and leave the door closed until cool. If the latch clicks but F09 persists, the door lock switch or wiring harness to the control board likely needs testing with a multimeter.
Do not force the door open during an active cycle; wait for the lock to release when the board de-energizes the lock motor—usually two to three minutes after canceling power on most Kenmore units.
Common causes
- Bake relay stuck closed on the ERC
- Sensor detached giving false cold reading
- Runaway clean cycle with latch fault
- External heat source too close to the range
Step-by-step fixes
- 1Turn off the breaker immediately and leave the door closed until cool
- 2Inspect the sensor mounting in the upper oven cavity
- 3Do not restart until F09 cause is identified
- 4Test bake element for continuity to ground when power is off
When to call a technician
F09 after cooldown with a good sensor strongly suggests ERC relay failure—replace the control board.
Affected models
- Kenmore Elite 790.75903
- Kenmore 790.46187300
- Kenmore 790.72409410
Prevention & maintenance
- Wipe the door gasket weekly and avoid overloading items against the seal—F09 often starts as a slow leak or latch misalignment.
- Record when F09 appears in the cycle and whether it clears after a 60-second power reset on your Kenmore oven—that detail speeds diagnosis if you call service.
- Keep the model and serial number from the rating plate when ordering parts for F09; Kenmore uses multiple revisions with different harness lengths and board firmware.
- Photograph wiring connector orientation before disconnecting any component while troubleshooting F09; reversed plugs on pumps and valves cause immediate repeat faults.
