Quick answer: An electric oven that overheats usually has a faulty temperature sensor, a bake element that will not switch off, or a stuck relay on the control board. The sensor is the most common cause: when it reads lower than the real temperature, the oven keeps heating past the setting and scorches food. A bake element that glows and will not cut off, or a relay welded closed, will also drive the heat up. An overheating oven is a safety concern, so stop using it, cut the power at the breaker, and have the sensor or board checked by a technician in Winnipeg.
Why your electric oven overheats
Overheating comes from a bad reading or a part that will not turn the heat off. Here is what each sign points to. If the oven has the opposite problem and will not heat up, that is a separate fault, and a poorly sealing oven door can throw temperatures off as well.
| Sign | Likely cause |
|---|---|
| Runs hotter than the set temperature | Temperature sensor reading low |
| Element glows red and will not cut off | Shorted bake element or a stuck relay |
| Overheats on every setting | Control board relay welded closed |
| Food scorches, burning smell | Sensor or thermostat fault |
| Very hot after self-clean | Door lock or thermostat stuck from the cycle |
The temperature sensor
The oven temperature sensor is the usual cause of overheating. This probe inside the cavity tells the control how hot the oven is. When it reads low, the control thinks the oven is cooler than it really is and keeps the element on, pushing the true temperature well past the setting. A sensor is tested for resistance and replaced when it drifts out of range.
A shorted element or stuck relay
The bake element should switch on and off through the cycle. If it shorts internally or the relay that powers it welds closed, the element stays on and the oven overheats no matter the setting. You may see the element glowing when it should be off. Here at Profixit, we check the element and the board relays together, since either can hold the heat on.
Safety first in Winnipeg
An oven that overheats is a fire and burn risk, not just a cooking annoyance. If food scorches on every setting or you smell burning, stop using the oven and switch off its breaker. Do not run the self-clean cycle on a suspect oven, since it drives the cavity to very high heat. A quick sensor or board check is far cheaper than a kitchen fire.
When to call a technician in Winnipeg
Call a professional when the oven runs hot on every setting, when the element will not cut off, or after a self-clean cycle leaves it stuck hot.

Frequently Asked Questions
Why is my electric oven overheating?
The most common cause is a faulty temperature sensor reading lower than the real temperature, so the oven keeps heating past the setting. A shorted bake element or a stuck control-board relay can also hold the heat on. Stop using the oven and have the sensor checked.
Is an overheating oven dangerous?
Yes. An oven that runs too hot is a fire and burn risk. If food scorches on every setting or you smell burning, switch off the oven at the breaker and do not run the self-clean cycle until it is inspected.
Why does my oven get too hot after self-clean?
The self-clean cycle drives the cavity to very high heat, and it can leave the door lock or thermostat stuck. If the oven stays too hot or will not unlock after self-clean, the thermostat or lock assembly likely needs attention.
