Oven Not Heating? 6 Checks to Do Before You Call

If your oven won't heat, check the breaker (electric ovens use a 240V double breaker), make sure the gas valve is open on gas models, confirm the oven isn't in demo, Sabbath or delay-start mode, and watch the igniter or bake element. A gas igniter that glows for over 90 seconds without lighting is weak and needs replacing; an electric element with a visible break has burned out.

6 checks you can do safely

1. Check the breaker. Electric ovens need both halves of a 240V breaker; one tripped half can leave the oven cold.
2. Check the gas valve. On gas ranges, the valve behind the range should be open and the cooktop burners should light.
3. Check the mode. Demo/showroom, Sabbath or a delayed start all stop heating.
4. Watch the igniter. Through the window, a gas igniter should glow and light the burner within about 90 seconds.
5. Inspect the elements. Electric bake and broil elements with blisters or breaks have failed.
6. Read the code. GE F-codes, LG F9/F19, Samsung C-codes and Frigidaire F10/F30 point to specific parts.

When to call a technician

• The igniter glows but the gas never lights (weak igniter or safety valve).
• The oven heats unevenly or 25°F+ off (sensor or calibration).
• You smell gas — leave the home and call Southwest Gas first.

Stay safe

Unplug the appliance (or switch off its breaker) before touching anything inside it, and never open a sealed refrigeration system, a gas valve or a microwave. If a code points to a part, the part has to be tested before it is replaced; we do that on the $75 diagnostic visit, credited toward the repair.
