Range Burner Won't Light or Keeps Clicking? Here's Why

A gas burner that clicks continuously but won’t light — or lights unevenly with a big pop — is one of the most frequent range calls we get across Los Angeles, which makes sense given how much of the city cooks on gas. The good news: most causes are simple and some you can fix yourself in a few minutes.

Clicking Nonstop, No Flame

If a burner (or all of them) clicks continuously even when nothing is turned on, the most common cause is moisture in the igniter switch. Boilover liquid — soup, pasta water, sauce — gets into the switch or spark module underneath the burner and causes it to cycle nonstop trying to find a spark.

What to try first: Turn off the burner, remove the grate and burner cap, and thoroughly dry the area around the igniter with a towel. Let it air dry for a few hours if it’s visibly wet. This resolves the issue more often than you’d expect.

If drying it doesn’t help: The switch itself may be corroded from repeated moisture exposure, and at that point it needs to be replaced rather than dried out.

Burner Won’t Light at All

If there’s no clicking and no flame, work through these in order:

1. Check the burner cap alignment. This sounds too simple to be the answer, but it’s genuinely one of the most common fixes. The burner cap needs to sit perfectly flat and centered — if it’s slightly off, the igniter can’t reach the gas stream properly. Lift the cap off, make sure it’s clean, and reseat it so it sits level.

2. Clean the burner ports. Food debris, especially from boilovers, can clog the small gas ports around the burner ring. A toothpick or thin wire (not a toothbrush bristle, which can break off inside) can clear visible blockages. Wipe the area clean and try again.

3. Check the igniter electrode. If the cap is aligned and ports are clear, look at the igniter itself — it’s the small ceramic or metal component near the burner that produces the spark. Cracks or heavy carbon buildup on the electrode prevent a reliable spark. This one usually needs replacement rather than cleaning.

4. Confirm gas supply. If one burner won’t light but others work fine, the issue is isolated to that burner’s igniter or valve — not a supply problem. If all burners fail simultaneously, check whether the gas supply to the house is on and whether other gas appliances are working.

Uneven or Low Flame

A flame that’s noticeably lower on one side, or burns with a yellow tint instead of blue, usually means partially blocked burner ports (the same debris issue as above) or, less commonly, an air-fuel mixture problem that needs a technician’s attention. A healthy gas flame should be mostly blue with maybe a small yellow tip — a heavily yellow or orange flame can indicate incomplete combustion, which is worth having checked.

Electric Ranges: A Different Set of Causes

If you have an electric range with a burner that isn’t heating, the diagnosis is different — usually a failed heating coil or, on smooth-top glass ranges, a failed heating element beneath the surface. These require checking continuity with a multimeter and are generally not a DIY fix on glass-top units, since the cooktop surface itself often needs to be lifted or removed.

Safety First: If You Smell Gas

If you smell gas near your range at any point — even faintly — stop immediately. Do not turn any switches on or off. Do not use your phone inside the house. Walk outside and call SoCalGas at 1-800-427-2200. Gas leaks around ranges typically come from a cracked supply line, a valve not seating properly, or a fitting that’s loosened over years of use — none of which should be diagnosed by ear or guesswork.

DIY Difficulty by Repair

Issue	DIY Rating	Notes
Moisture in igniter switch	Easy	Dry thoroughly, wait, retest
Misaligned burner cap	Easy	No tools needed
Clogged burner ports	Easy	Toothpick or thin wire, careful cleaning
Igniter electrode replacement	Moderate	Accessible on most ranges
Spark module replacement	Moderate–Hard	Wiring involved
Electric coil/glass-top element	Hard	Often requires lifting cooktop surface

When to Call a Tech

• You’ve dried the igniter, checked alignment, and cleared debris, and the burner still won’t light reliably
• You smell gas at any point
• You have a professional-grade range (Wolf, Viking, Thermador) — these use higher-energy igniter systems and parts that vary by model year
• The issue is on an electric or glass-top range
