Runaway temperature
The control saw the oven heating faster or higher than the setting allows — or heating with nothing set. The oven sensor has shorted, or a relay on the board has stuck on.
- Turn the range's breaker off now. If the oven is hot with nothing set, it stays off until it is fixed.
- After 30 seconds, turn the breaker back on and watch the display with the oven off: F10 again within a few minutes, or heat with no setting, is the board; F10 only when you start a bake is more often the sensor.
The oven temperature sensor (the probe at the top back of the oven cavity) or the oven control board — a technician's part either way. The range is not used until it is replaced.
F10 is stop-and-call: an oven that heats on its own is a fire risk. Turn the breaker off and leave it off; on a machine under warranty this is a warranty service call, made the same day you see the code.
