Quick answer: An electric oven not heating almost always comes down to one component. Set the oven to bake and watch the element. A healthy bake element glows evenly orange within a few minutes. If it stays dark, or glows in patches, it has burned out, and that is the most common cause by a wide margin. If the element looks fine, the next suspects are a blown thermal fuse, a drifted temperature sensor, or the control board. A cooktop that still works while the oven is dead points at one leg of the 240-volt supply rather than the oven itself. Profixit services electric ovens only.
Key Takeaways
- Watch the element on bake. That single test resolves most of these.
- An oven that died right after a self-clean cycle has usually blown its thermal fuse.
- Working cooktop plus dead oven means a supply problem, not an oven fault.
- Most causes here are inexpensive parts, and an electric oven lasts 13 to 15 years.
What an electric oven not heating usually means
Set the oven to bake at a moderate temperature and look through the door with the light on. The bake element is the loop at the bottom of the cavity, or behind the rear panel on a fan oven.
A healthy element glows evenly orange along its whole length within about five minutes. Failure looks like one of three things: it stays completely dark, it glows only along part of its length, or it has a visible blister, split or bright pitted spot.
Plenty of elements fail with no visible damage at all, which is why the glow test is more reliable than looking for a break.
On a convection oven the element is hidden behind the back panel, so this test is not available and the diagnosis has to be done differently.
| What you see | Likely cause | Yours or ours |
|---|---|---|
| Element stays dark, oven cold | Burned-out bake element | Ours |
| Glows in patches, cooks unevenly | Element failing | Ours |
| Died right after a self-clean cycle | Thermal fuse, sometimes the board | Ours |
| Cooktop works, oven dead | One leg of the 240-volt supply | Breaker first |
| Everything dead, no display | Breaker or supply | Breaker first |
| Heats but never reaches temperature | Element weakening, or door seal | Ours |
| Broil works, bake does not | Bake element or its relay | Ours |
| Display on, no response to bake | Control board or sensor | Ours |
The self-clean cycle connection
If the oven stopped heating within a day or two of running a self-clean cycle, you have almost certainly found your answer.
A pyrolytic self-clean cycle heats the cavity to around 900°F, far above any cooking temperature, and holds it there for hours. Everything around the cavity takes that heat too. The thermal fuse is a one-time safety device designed to blow rather than let things get dangerous, and it frequently does exactly that. The control board, sitting close to all that heat, sometimes does not survive either.
A blown thermal fuse is an inexpensive part and a satisfying repair. A cooked control board on an older oven is the point where replacement sometimes wins.
Worth knowing for next time: on an oven more than about eight years old, an overnight baking soda clean is the lower-risk option. We cover the method in how to properly clean your appliances.
Check the breaker properly
An electric range runs on 240 volts, supplied as two 120-volt legs. The oven element needs both. Some other functions need only one.
That produces the single most misdiagnosed symptom in this whole category: a range where the cooktop elements work, the clock and display are lit, and the oven does nothing at all. People conclude the oven is broken. Often the supply has lost one leg.
Check it properly. A double-pole breaker can trip on one side and still look like it is on, so switch it fully off and back on rather than trusting its appearance. If that restores the oven, have the cause looked at rather than assuming it was a one-off.
Where the breaker is fine and half the range is dead, the fault is in the supply, the terminal block at the back of the range, or the internal wiring. Terminal blocks loosen and burn over time, especially on ranges that have been moved. That is the point to stop and book it.
The temperature sensor
Inside the cavity, usually at the back left, there is a thin metal probe on a bracket. It tells the control board what temperature the oven is at.
A failed sensor stops the oven heating entirely. A drifted one is subtler and more annoying: the oven heats, but to the wrong temperature, confidently. Everything comes out under or over done by roughly the same amount, and adjusting the dial does not help because the error moves with it.
It is a common part and a routine replacement.
The door, which people forget
A door seal that has hardened, torn or come away from its clips lets heat out continuously. So does a door that no longer closes squarely because a hinge has weakened.
The oven compensates by running the element more, which means it struggles to reach temperature and cooks unevenly on the side nearest the gap. It mimics an element or sensor fault closely.
Check it with a hand around the closed door on a warm oven, carefully, feeling for escaping heat, and look at whether the door sits parallel to the front. See fixing a faulty oven door and a loose or broken hinge.
Electric only
Profixit repairs electric appliances only. We do not repair gas ovens, gas ranges, gas cooktops or dual-fuel appliances. Everything above is written for electric ovens: conventional, convection and wall-mounted. A gas appliance needs a technician licensed for that work, and we would rather say so when you call than send someone who cannot help.
Before we arrive
Note whether the cooktop still works, whether the broil element heats, and whether anything changed just before it started, particularly a self-clean cycle or a power cut. That is most of the diagnosis.
Leave the oven as it is. Do not unplug it, do not pull it out from the wall, and do not start removing the back panel, because a fault still present when the technician arrives is one that usually gets resolved in a single visit.
Diagnosis is $85 in Winnipeg and $120 outside the city, and the quote afterwards is the whole price rather than an amount added to the call-out.

Frequently Asked Questions
Why is my electric oven not heating up?
The most common cause is a burned-out bake element. Set the oven to bake and watch it. A healthy element glows evenly orange within a few minutes. If it stays dark, or glows only in patches, it has failed. After that the usual suspects are the temperature sensor, a blown thermal fuse and the control board.
My oven stopped heating right after a self-clean cycle.
That is a pattern we see constantly. A self-clean cycle runs the cavity far above cooking temperature for hours, and the thermal fuse is a one-time safety device that frequently blows. The control board sits close to that heat too. The fuse is an inexpensive repair, and it is worth finding out why it blew.
The cooktop works but the oven does not. What does that mean?
An electric range runs on a 240-volt supply made of two 120-volt legs. Losing one leg takes out half the appliance, which is why a working cooktop with a dead oven, or the reverse, is such a common pattern. Check the double-pole breaker first by switching it fully off and back on.
Is an oven that will not heat expensive to fix?
Usually not. A bake element, a temperature sensor or a thermal fuse are among the cheaper appliance repairs, and an electric oven lasts 13 to 15 years. A failed control board is the expensive exception.
Can I replace a bake element myself?
It is one of the more accessible repairs on some models, but it involves a 240-volt circuit and terminals that can be scorched or seized. If the element failed because of a wider fault, replacing it alone will not hold.
Does Profixit repair gas ovens?
No. Profixit services electric appliances only. We do not repair gas ovens, gas ranges or dual-fuel appliances. A gas appliance needs a technician licensed for that work.
