Most common causes
- Failed bake element. On electric ovens the bake element at the bottom can burn out. You may see a crack, blister, or break, and the oven heats slowly or not at all.
- Weak gas igniter. On many gas ovens the igniter must draw enough current to open the gas valve. A weak igniter may glow but never let the gas flow.
- Tripped breaker or power issue. Electric ranges use a double breaker. If one side trips, the cooktop or clock may work while the oven does not heat.
- Temperature sensor problem. The oven sensor tells the control the temperature. A faulty sensor can stop heating or cause wrong temperatures.
- Control board or settings. A control lock, Sabbath mode, or a delayed bake setting can keep the oven from heating. A failed control board can also stop the heat.
- Gas supply off. If the gas valve behind the range is closed or other gas appliances are also out, the oven has no gas to burn.
What you can safely check
- Make sure the oven is not in control lock, Sabbath mode, or a timed bake setting.
- For electric ovens, check the breaker panel and reset the range breaker fully off and back on.
- With the oven off and cool, look at the bake and broil elements for breaks or blisters.
- For gas ovens, check that the cooktop burners light. If they do not, the gas supply may be off.
- If you smell gas, do not light anything or use switches. Leave the house and call SoCalGas or 911 from outside.
Call a technician if
- The igniter glows but the oven never lights
- An element is visibly broken or sparks
- The oven heats but is far off the set temperature
- The display shows an error or the oven shuts off on its own
- You smell gas
What affects the repair cost
Bake elements, igniters, and temperature sensors are common repairs. Control boards cost more and depend on the model. We test first and give you the price before we start.
