Whirlpool range & oven error codes: most of them are the oven sensor, the door lock, or a stuck key.

The temperature probe inside the oven (the thin rod at the back wall, top) is reading open — the control sees no temperature at all. Older ranges printed F3.

1. Switch the breaker off (unplug a gas range) for one minute and set a bake. A sensor code that clears and stays gone was a power blip.
2. Look at the probe at the back of the oven cavity: it is straight and nothing has knocked it (a rack slammed in, a pan pushed back).

F3E0 that returns is the oven temperature sensor — a part behind the back wall, a technician's job. The cooktop still works meanwhile.

The oven temperature probe is reading shorted — a temperature far higher than the oven could be. Older ranges printed F4.

1. Switch the breaker off (unplug a gas range) for one minute and set a bake.

F3E1 that returns is the oven temperature sensor or its wiring — a part, a technician's job.

The sensor read the oven over the limit for a bake or a broil. Either the oven overheated or the sensor is drifting high. Older ranges printed F2.

1. Press Cancel and let the oven cool with the door closed for an hour.
2. Nothing is blocking the oven vent (on the cooktop surface at the back, or under a rear burner) — foil on the oven floor or over a rack sends the heat where the sensor sits.
3. Reset (breaker off one minute) and set a bake at 350°F with an oven thermometer on the middle rack; judge it after 20 minutes.

An oven that holds 350°F on the thermometer and threw the code once was a one-off. An oven that overshoots, or prints F3E2 again, is the sensor or the control's bake relay — stop using the oven and call it in.

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

1. Press Cancel and let the oven cool fully — the door stays locked until it has.
2. The oven vent was clear and the racks were out (racks left in during a clean can hold heat against the sensor).

One F3E3 on a clean with racks in and a cool-down is a one-off; use the oven normally. A second one is the sensor or the control — a service call. Skip the self-clean until it is seen.

Not a fault. The oven controls are locked so a child cannot turn the oven on; the display reads LOC or shows the lock icon.

1. Press and hold the key the panel marks Control Lock (on many models Cancel, or Start, or a lock icon) for three seconds until the display clears.

The panel answers again. The cooktop knobs are never locked by it.

Not a fault. The control is in the mode a store floor uses — the display and the keys work, the oven and (on an electric range) the elements never heat.

1. The display reads dEMO (or shows it when a key is pressed).
2. Press and hold the pair of keys the use-and-care guide names for your model (on many ranges Start and Cancel, or a numbered key sequence) until dEMO goes out.

The oven heats once the mode is off. The guide for the exact model is on whirlpool.com by model number and names the keys.

Not a fault. The oven holds a bake with the display, the tones and the lights off for the Sabbath; the keys do nothing until the mode ends.

1. Press and hold the keys the panel names for Sabbath (on most models Start and Cancel together, or a numbered key held for five seconds) until the display wakes.

The control answers again.

Not a fault. The power went out and came back; the clock is blinking and any bake that was running stopped.

1. Press Cancel, set the clock, and start the bake again.

Nothing to fix. PF with no outage is a loose connection at the outlet or the breaker — an electrician's look.
