Kenmore Oven/Range Error Code F2 — Oven Overheating / Exceeded Safe Limit
What this means
The F2 error code on Kenmore ovens and ranges means the oven temperature has exceeded the pre-set maximum safe temperature (typically 590–620°F during normal baking, or higher during self-clean). This is a critical safety error. The oven will shut off heating and may lock the door. Causes include a stuck-on relay on the control board, a faulty temperature sensor, or a malfunctioning oven control.
Step-by-step fix
4 stepsTurn off the oven immediately
If the oven is actively overheating, turn it off at the circuit breaker immediately. Open the oven door to allow heat to escape (if the door isn't locked). Do not use the oven again until the issue is diagnosed.
If the oven door is locked and won't open, do not force it — wait for the oven to cool below 500°F, which may take 30–60 minutes.
Test the temperature sensor
Once the oven has cooled completely, test the oven temperature sensor for resistance. At room temperature, it should read approximately 1,080–1,100 ohms. A sensor reading too low could cause the control board to think the oven is colder than it actually is, resulting in continuous heating.
A sensor that reads 900 ohms instead of 1,100 at room temp would make the board think the oven is about 150°F hotter than set — leading to overheating.
Check for a stuck relay on the control board
Unplug the oven. Access the electronic control board (behind the clock/display panel). Look for any signs of arcing, burn marks, or damaged relays. A stuck relay can keep the heating element energized even when the control tries to shut it off.
If you smell burned electronics or see darkened areas on the board, the relay has likely welded shut — the board must be replaced.
Verify with an oven thermometer
After replacing the sensor or board, place an oven thermometer inside and preheat to 350°F. Verify the oven reaches the set temperature and cycles off the heating element correctly.
Watch the element through the oven window — on an electric oven, the element should glow red when heating and go dark when the set temperature is reached.
When to call a professional
Overheating is a safety issue. If you cannot confidently identify the cause (sensor vs. control board relay), have a qualified technician diagnose and repair the oven. Do not continue using an oven that overheats.
