KitchenAid range & oven error codes: the oven sensor, the door lock, or a key — a short list.

The oven temperature sensor — the thin probe on the oven's back wall, up high — reads open; the control sees no temperature at all and will not heat.

1. Breaker off (or unplug) for one minute and try Bake. A one-time code after a power surge stays gone.
2. Look at the probe on the back wall: it stands straight out, not bent against the wall by a rack slid in hard or a sheet pan.

A sensor that still reads open is the sensor or its plug behind the oven's rear panel — a technician's part. The cooktop keeps working; the oven stays cold until it is changed.

The same sensor reads shorted — a temperature far above anything the oven could reach.

1. Breaker off (or unplug) for one minute and try Bake.

The same part as F3E0 — the sensor or its wiring; a technician's job.

The control measured the oven hotter than a bake or a broil allows. Either the heat kept coming past the set point, or the sensor is reading high.

1. Press Cancel. If the oven keeps heating with everything off, switch the breaker off and leave it off.
2. Breaker off one minute; set Bake at 350°F with an oven thermometer on the middle rack and watch the first fifteen minutes — a reading that climbs past 400°F is a runaway.

An oven that runs past its set point is a relay stuck on the control board, or a sensor drifting low — either is a technician's part. Keep the oven off until it is checked.

The sensor read the oven over the limit during a self-clean cycle.

1. Let the oven cool fully, then breaker off one minute and set the clock.
2. Try a Bake at 350°F with an oven thermometer on the rack; a bake that holds its temperature says the fault lives in the clean cycle alone.

A clean cycle that overheats is the sensor reading low or a relay on the control holding — a technician's part. Bake normally meanwhile; skip self-clean until it is seen.

Not a fault. The oven keys are locked so a child cannot start it; the display reads LOC or shows the padlock.

1. Press and hold the key the panel marks Control Lock (on many, the Start key or the padlock symbol) for three seconds until LOC leaves the display.

The oven answers again.

Not a fault. The display and the keys work for a sales floor, but no element, burner or oven heats. A range from a floor display or an outlet load sometimes arrives this way.

1. The display shows dEMO, or every setting takes and nothing warms.
2. Set the clock first, then press and hold the pair the manual names (on many, Cancel with the clock key, or the Start key held for about five seconds) until dEMO leaves the display.

The oven heats again. If the manual's pair does nothing on yours, a technician exits it from the control's service mode.

Not a fault. The oven holds a bake with the lights, the tones and the display quiet for the Sabbath; the timer, the broiler and self-clean do not work in it.

1. Press and hold the key the manual names (on many, the clock key or the Start key for about five seconds) until the display returns.

Normal control comes back; on most models the mode also ends by itself after about 72 hours.

Not a fault. The power dropped and came back; the clock lost its time and any bake that was running stopped.

1. Press Cancel and set the clock — on most of these the oven will not start until the clock is set.

Nothing to fix. PF with no outage in the house is a loose cord or a breaker that is tripping; a 240V cord and outlet are a licensed electrician's to look at.
