How to Fix a Gas Stove Burner That Won't Light

Most burners won't light due to clogged burner ports, dirty igniter electrodes, or food debris blocking the gas flow, all of which can be fixed with basic cleaning.

1. Cool and Clear the Space. Turn off the gas supply to the burner and wait at least 30 minutes for everything to cool down. Remove the burner grate and drip pan if your stove has them. This gives you clear access to work safely.
2. Scrub Away the Grime. Lift off the burner cap (the round piece on top) and the burner head underneath. Wash both pieces in warm, soapy water. Use an old toothbrush to scrub away grease and food residue. For stubborn buildup, soak them for 15 minutes before scrubbing.
3. Unclog Every Gas Hole. Look for small holes around the burner head where gas comes out. Use a thin wire, paperclip, or needle to gently poke out any debris from each port. Don't use wooden toothpicks as they can break off inside. Work methodically around the entire circumference.
4. Restore the Spark. Find the small metal electrode near the burner (looks like a tiny metal post). Gently wipe it down with a damp cloth or cotton swab to remove grease and food particles. A dirty electrode can't create the spark needed to light the gas.
5. Sweep the Base Clean. With the burner parts removed, clean around the base where the burner sits. Remove any spilled food, grease, or debris that might interfere with gas flow. Wipe the area clean and dry thoroughly.
6. Put It Back and Light Up. Make sure all parts are completely dry, then reassemble in reverse order. The burner head should sit flat and aligned properly. Replace the cap, ensuring it sits centered and stable. Turn the gas back on and test the burner.
