If the oven display and light work but the cavity never gets hot, start by separating electric-oven problems from gas-oven problems. The likely repair depends on the fuel type.
These steps apply to electric and gas ovens and ranges. Gas igniter, burner, valve, and gas-line work should be handled by a licensed technician.
Does this affect you?
Electric ovens commonly stop heating because a bake or broil element failed, the breaker tripped, or a temperature/control part is not calling for heat. Gas ovens most often fail because the igniter is too weak to open the gas valve reliably.
Quick checks before assuming a part failed
- Confirm the oven is set to Bake and the target temperature was actually accepted, not just entered into the timer.
- On a gas range, check whether surface burners still light. If none do, the gas supply may be off.
- On an electric oven with a visible bake element, look for a split, blister, bright hot spot, or burned section.
- Check the oven breaker. Many electric ovens use a dedicated high-amperage circuit.
Turn off power at the breaker before touching elements, panels, or wiring. Let the oven cool fully before inspecting inside. Never attempt gas burner, igniter, gas valve, or gas-line repairs yourself. If you smell gas, stop using the oven and call the gas utility or a licensed technician.
Replace a failed bake element on an electric oven
A visibly damaged exposed element is one of the simpler electric-oven repairs if you are comfortable working with power disconnected.
- Turn power off at the breaker.
- Remove the screws holding the bake element to the rear oven wall.
- Pull the element forward gently until the connectors are visible.
- Disconnect the old element and attach the matching replacement part.
- Reinstall the screws, restore power, and test Bake briefly for even heating.
Weak or no ignition on a gas oven
A gas oven igniter can glow and still be too weak to open the valve correctly.
- Listen when the oven starts. A healthy ignition sequence usually lights within about 30 to 45 seconds.
- If the igniter glows for much longer without flame, it may be weak.
- If you hear clicking with no ignition or smell gas, turn the oven off and do not keep trying.
- A weak igniter is common, but replacement involves gas components and should go to a technician.
If the oven heats but cooks too hot or too cold, use an oven thermometer and check the calibration or temperature offset setting instead of treating it as no heat. On convection models, a dead fan can also mimic a heating issue by causing uneven cooking.
If an electric element looks fine but the oven still will not heat, the thermostat, sensor, relay, or control board may need diagnosis with a meter.
