Quick Answer
An oven that will not turn off is usually a stuck control-board relay or a failed temperature sensor. Treat it as a safety issue: shut it off at the breaker if it stays hot, and have a local technician replace the faulty part.
An oven that will not turn off is usually caused by a stuck relay on the control board or a failed temperature sensor. Either way, treat it as a safety issue first and a repair second. Here is what to do right now and what is likely going on.
Do this first
If the oven stays hot and the controls will not shut it down, turn it off at the circuit breaker. That safely cuts power without you having to reach near the heat. Do not leave a stuck oven running while you are out of the house.
Why an oven gets stuck on
The control board uses small relays to switch the heating elements on and off. If a relay sticks closed, the element keeps getting power. A failed temperature sensor can also confuse the board into running longer than it should. If your oven has the opposite problem, our oven not heating guide covers that side.
What not to do
Do not try to pry into the control board yourself. The Consumer Product Safety Commission stresses caution with any appliance that is overheating or behaving unpredictably.
Getting it fixed safely
A stuck relay or bad sensor is a precise repair, so the safe path is to get connected with a local Fairfield technician who can test and replace the part. Our oven repair page explains what to expect.
Frequently asked questions
Is it safe to use the oven again after it cools?
Not until the cause is found. A relay that stuck once can stick again, so have it checked first.
Could it just be the knob or touchpad?
Sometimes, yes. A faulty touchpad can send the wrong signal, which a technician can confirm quickly.
