What's actually causing this

Electric ovens fail to heat when the bake or broil element burns out. Gas ovens typically fail because the igniter weakens over time and can't get hot enough to open the gas valve, even though it glows orange.

Step-by-step fix

  1. 1

    Check the clock and control lock

    Many ovens default to a clock or sabbath mode that disables cooking. Check the display for a lock icon or flashing clock. Consult your manual to exit this mode before assuming there's a hardware fault.

  2. 2

    Inspect the bake element (electric ovens)

    Turn off the oven at the breaker. Look at the element at the bottom of the oven interior. A burned-out element will show a visible crack, blister, or burn hole. If it looks normal, test it with a multimeter for continuity.

  3. 3

    Replace the bake element

    Unscrew the element from the oven back wall. Pull it forward to expose the wires — take a photo first. Disconnect the wires, connect to the new element, and reverse the process.

  4. 4

    Test the igniter (gas ovens)

    Turn on the oven and watch the igniter through the oven window. If it glows orange but the burner doesn't light after 90 seconds, the igniter is too weak. A healthy igniter lights the gas within 30–60 seconds.

  5. 5

    Replace the igniter

    Turn off the gas supply valve. Remove the oven bottom panel and burner cover to access the igniter. It's held by two screws and a wire connector. Replace with an exact match for your model number.

Stop and call a pro if you see this
  • You smell gas when the oven is on — shut off gas and call a tech immediately.
  • The oven broiler works but the bake function doesn't, and the element tests fine — likely a control board issue.
  • The oven runs hot or cold by more than 50°F even after recalibration.
  • The oven is a dual-fuel or convection model with complex electronics.
