Oven Not Heating? Causes and Fixes
When an oven will not heat, the cause depends on the fuel. Electric ovens usually have a burned-out bake element or a tripped breaker. Gas ovens most often have a weak igniter that glows but does not open the gas valve. A bad temperature sensor or control can also cause it.
Likely causes
- Burned-out bake or broil element (electric). Look for breaks or blisters on the element.
- Weak or failed igniter (gas). It may glow but not light the burner.
- Tripped breaker or blown fuse (electric)
- Gas supply valve off (gas)
- Failed temperature sensor or thermostat
- Control board or settings issue, such as Sabbath mode or a delay timer
Safe DIY checks
Safety first: unplug the appliance or switch off its breaker before touching anything inside, and shut off the water or gas supply where it applies. If you smell gas, leave the house and call your gas utility from outside.
- Check that the oven is not set to a timer, delay start or lock mode.
- On an electric oven, reset the breaker and look at the bake element for visible damage.
- On a gas oven, make sure the stove top burners light, which confirms gas is on.
- Watch the gas igniter through the bottom panel. If it glows for a long time with no flame, it is likely weak.
- Use an oven thermometer to see how far off the temperature is.
When to call a pro
- The element or igniter looks bad, or the checks do not find the issue
- You have a gas oven (leave igniter and gas valve work to a pro)
- You smell gas: leave the house and call your gas utility
- The oven shows an error code or the display is dead
What does it cost?
Call for a quote. Repair costs depend on the brand, the model, the part and the shop, so this site does not publish price ranges. Ask each shop for its diagnostic or trip fee and a written quote after diagnosis.
Repair or replace?
Elements, igniters and sensors are usually affordable repairs. Control boards on older ranges can cost enough that replacement is worth comparing. Read the repair or replace guide.

FAQ
Why won't my electric oven heat?
Usually a failed bake element, a tripped breaker, or a bad sensor or control.
Why won't my gas oven heat?
Usually a weak igniter. It glows but not hot enough to open the gas valve. A gas supply issue or control problem is less common.
Is it safe to fix an oven myself?
Basic checks are fine. Leave gas parts and wiring to a qualified technician.
