Gas ovens usually stop heating because of a weak igniter. Electric ovens usually stop because of a burned-out bake element. Other causes include a bad temperature sensor, a tripped breaker, a delay-start setting, or a control board fault.
Why Gas Ovens Stop Heating
Weak igniter
The igniter must get hot enough to open the gas valve. A weak one glows but doesn't light the burner.
Gas supply off
The shut-off valve behind the range may be closed after cleaning or moving it.
Bad gas valve
Less common, but a failed valve won't let gas reach the burner.
Temperature sensor
A bad sensor sends the wrong reading, so the oven stops heating too soon.
Why Electric Ovens Stop Heating
Burned-out bake element
Look at the bottom element. Blisters, breaks or dark spots mean it's failed.
Tripped breaker
Electric ranges use a double breaker. If half trips, the oven may not heat.
Broil element failure
If the oven heats on bake but not broil, the top element may be out.
Control board or relay
A failed board or relay can stop power to the elements.
Quick Oven Checks You Can Do at Home
- Make sure no delay start or timer is set.
- Check the breaker panel for a tripped breaker.
- For electric ovens, look at the bake element for visible damage.
- For gas ovens, watch the igniter. It should glow bright and light the burner within a minute or two.
- Note any error code on the display.
Some brands use codes to show the problem. For example, GE appliance repair customers may see F3 or F4 for a sensor issue.
Oven Heats Unevenly? Here's Why
Burnt bottoms and raw tops often mean a weak element, a failing convection fan, or a sensor that's off. Using dark pans or blocking vents with foil can also cause uneven baking. Never line the oven bottom with foil.
When to Call for Oven Repair
Call a technician if the oven still won't heat after these checks, if you smell gas, or if you see sparks. We test igniters, elements, sensors and controls and fix the real cause. See our oven repair page. If burners on top won't work either, our stove and range repair service can help.
