Oven problem
Why is my oven not heating?
On electric ovens, look at the bake element: a visible break or blister means it has failed. On gas ovens, a weak igniter is the usual culprit; it glows but never gets hot enough to open the gas valve. If you smell gas, leave the house and call the gas utility.

Gas and electric fail differently: oven not heating
Both depend on a sensor and a control. Electric ovens rely on elements and relays; gas ovens on an igniter that opens a safety valve.
- Electric
- Bake element, broil element, thermal fuse, control relay.
- Gas
- Igniter, safety valve, gas supply.
- Both
- Temperature sensor and control settings.
Signs and causes: oven not heating
| Sign | Likely cause | What fixes it |
|---|---|---|
| Electric: broiler works, bake does not | Bake element failed | Element replaced |
| Gas: igniter glows, no flame after 90 seconds | Weak igniter | Igniter replaced |
| Heats but temperature wrong | Sensor or calibration | Sensor tested, offset adjusted |
| Nothing works after self-clean | Thermal fuse or lock | Fuse or lock replaced |
Safe checks: oven not heating
Set the clock
Some ovens will not heat until the clock is set after a power cut.
Check for control lock
A lock icon disables the oven.
Look at the element
Cracks, blisters or a burned spot mean replacement.
Test with a thermometer
Confirm the actual temperature at 350 °F.

What to tell the technician about the oven
Give the model number and say whether the oven is gas or electric, whether the broiler works when the bake function does not, and whether anything happened just before it stopped, such as a self-clean cycle, a power cut or a spill. Note any error code on the display exactly as shown.
On a gas oven, say how long you waited and whether you saw the igniter glow through the slots in the oven floor. A glow without a flame after about a minute and a half almost always means a weak igniter. On an electric oven, a visible break or blister on the bake element means the element has failed, and a technician can often replace it in one visit if the part is in stock.
Questions people ask: oven not heating
How long should a gas oven take to light?
Typically under a minute or so after the igniter glows. Much longer suggests a weak igniter.
Can I replace a bake element myself?
On many models, yes, with the power off at the breaker. If terminals are burned, call a technician.
Why did my oven stop after self-clean?
The high heat can blow a thermal fuse or damage the lock.
Why does my oven heat but take forever to preheat?
A weak gas igniter or one failed section of an electric element slows preheating. A door gasket that no longer seals also lets heat escape.
This page is general safety information, not a diagnosis. Appliances combine electricity, water and sometimes gas. If you are unsure whether something is safe, unplug it or switch it off at the breaker and have a technician inspect it. For a gas smell, leave and call 911 or the gas utility.
