Oven won't heat

Most likely causes

What's actually going on

• Burned-out bake element (electric)If the element doesn't glow evenly orange — or has a visible break or blister — it's done.
• Weak igniter (gas)The #1 gas-oven repair: a tired igniter glows but never gets hot enough to open the gas valve, so it clicks but won't light or heat.
• Bad oven temperature sensorA failed sensor feeds the control the wrong reading, so the oven heats wrong or not at all — often with a fault code.
• Control board faultThe electronic control fails and won't call for heat.

Check it yourself

Safe steps before you call

Work through these in order — they're the same first checks a good technician makes.

• Watch the element or igniter. Electric: does the bake element glow fully? Gas: does the igniter glow bright orange and light the burner within ~90 seconds?
• Note any error code. Write down the exact code — it points straight at the failed part.
• Rule out the clock/timer. A delay-bake or timer mode set by accident can lock out the oven — cancel and retry.
• Never bypass a gas safety. If a gas oven isn't lighting, don't force it — call.
