Quick Answer: Kill Power at the Breaker First#
Most likely: a relay on the control board (W10834736) has welded shut and is feeding the heating element power continuously, so the oven keeps heating no matter what the display shows — this is the most common cause and a genuine fire hazard. The other main cause is a temperature sensor that has shorted to ground: it sends the board a false low reading, so the board commands maximum heat indefinitely. Before any diagnosis, kill power at the breaker (close the gas valve on a gas range), and do not restore power until the fault is found. These are the two failures behind almost every "won't turn off," and both are electrical, not a stuck knob.
Likely Causes at a Glance#
| Cause | What is happening | What to check |
|---|---|---|
| Welded relay on control board (W10834736, most common) | A surge fused the relay contacts, so the element gets constant power | With power off, inspect and test the board relay; a welded relay stays closed |
| Shorted temperature sensor (WPW10181986) | Sensor shorted to ground reads false-low, so the board never stops calling for heat | Measure sensor resistance; near 0 ohms is a short — replace before restoring power |

Walking Through the Diagnosis#
Treat this as urgent: an oven that will not stop heating is a fire risk, so turn the breaker off immediately (and close the gas supply valve on a gas model), and leave it off until you have identified and fixed the cause. Whirlpool built-in ovens are often hardwired, so the breaker is the only safe disconnect. Have a multimeter and, because Whirlpool uses Torx fasteners rather than Phillips, a set of Torx drivers (T15, T20, T25) so you do not strip the panel screws.
With power off, test the temperature sensor first because it is the quicker check: measure its resistance, and a reading near 0 ohms means it has shorted to ground — replace it (WPW10181986) before restoring power, since a shorted sensor tells the board the oven is cold and drives the element to full heat. If the sensor reads normal, the fault is the control board (W10834736): a relay that switches the element can weld its contacts closed after a power surge, and once welded it passes current to the element continuously regardless of what you set or how the sensor reads. A welded relay cannot be reset — the board is replaced. If your oven shows a code alongside the symptom, note it exactly; the related codes here are F1E0, F3E0, and F3E2, and whether a code appears constantly or intermittently helps a technician prepare the right part. Because both root causes leave the element energized with no way to shut it off from the controls, do not keep using the oven or rely on the door or knobs — the breaker is your off switch until it is repaired.
Repair or Replace? The Short Version#
A good rule is that if the repair costs less than 50% of a comparable new oven and the unit is under about eight to ten years old, repair is the better investment — and a temperature sensor or a control board both sit well under that line, so this is almost always a repair. What is not negotiable is safety: because the element stays powered, this is not a symptom to live with or diagnose casually. Keep the breaker off, confirm the sensor or board, and if you are not comfortable testing a live-heat fault, have it done — book an EasyBear technician.

Frequently Asked Questions#
Why won't my Whirlpool oven turn off, and is it dangerous?#
Yes, it is dangerous — the element is getting continuous power. The most common cause is a welded relay on the control board (W10834736) that no longer opens, and the second is a temperature sensor shorted to ground that keeps commanding maximum heat. Kill power at the breaker immediately and leave it off; do not rely on the knobs or door, because neither can stop a welded relay.
Can I fix a Whirlpool oven that won't turn off myself?#
You can test the temperature sensor with a multimeter — near 0 ohms means it shorted and needs replacing (WPW10181986) — but do this only with the power off and do not restore power until the fault is resolved. A welded relay means a control-board replacement. Because the failure leaves the element live, if you are not confident testing it safely, treat it as a call for professional service.
What do the F1E0, F3E0, and F3E2 codes mean here?#
They are Whirlpool oven error codes that can appear alongside a won't-turn-off symptom and point toward a temperature-sensor or control-board fault. Note the exact code and whether it shows constantly or intermittently, because that speeds up diagnosis and parts selection. The code does not change the immediate action: kill power at the breaker and keep it off until the sensor or board is repaired.
