Gas Stove Burner Won't Light — How to Fix It
When a gas stovetop burner clicks but won't light — or lights on some burners and not others — the cause is almost always a dirty burner, a wet igniter, or a misaligned burner cap. These are quick, no-tools fixes.
1. Clean the Burner Ports
Food and grease clog the little gas-port holes around the burner ring. With the burner off, scrub the ring and clear each port with a straightened paperclip or needle (not a toothpick — it can break off and clog). Clogged ports are the top cause of weak flame or no light.
2. Check the Burner Cap Alignment
The metal burner cap must sit flat and centered on the base. If it was knocked askew during cleaning, the burner won't light evenly. Lift it and reseat it squarely.
3. Dry a Wet Igniter
After cleaning or a boil-over, moisture on the igniter stops it from sparking, or it clicks without lighting. Let everything dry fully, or dry it with a hair dryer. If one burner clicks but won't spark while others do, the igniter or its wiring may be failing.
4. Clicking That Won't Stop
A burner that keeps clicking even when off usually has moisture or food under the cap, or a stuck igniter switch. Clean and dry thoroughly. If it persists, the spark module or igniter switch needs replacement.
