Smell gas? Stop here.

If you smell gas, do not try to light the grill and do not flip any electrical switch. Turn off the propane tank valve, step away, and call your gas supplier. A leak is not a DIY fix.

The fix ladder (free fixes first)

Work these in order. The first four cost nothing. Only reach for a part if you've cleared every rung above it.

Check the propane supply

No gas smell at all? Start here.

Deep dive

Shake the tank. A full 20 lb tank feels heavy; an empty one almost weightless. Check the gauge if you have one, and make sure the regulator knob is fully open (counterclockwise).

Refill or swap an empty tank. If the tank has gas but nothing flows, the regulator's safety bypass is the likely culprit. That's the next rung.

Reset the regulator's safety bypass

Tank has gas but the flame is weak, lazy, or won't light.

Deep dive

A common cause after a tank swap is the regulator's safety bypass. Most consumer propane cylinders made since the early 2000s have an Overfill Prevention Device (OPD). If you open the tank valve too fast, the regulator limits gas flow to a trickle as a safety response.

  1. Turn all burner knobs off.
  2. Close the tank valve fully (clockwise).
  3. Disconnect the regulator from the tank.
  4. Open the grill lid.
  5. Wait 30 seconds.
  6. Reconnect and hand-tighten.
  7. Open the tank valve slowly, about one full turn over 3 to 4 seconds.
  8. Wait another 30 seconds before lighting.

This resolves it in most cases. If flow is still weak after the reset, the regulator itself may be failing. See the parts section.

Check the igniter battery

No click at all? A dead or reversed battery is the usual reason.

Deep dive

Find the battery compartment, usually on the side or front of the control panel. It takes one AA or AAA (varies by model). Pull the battery and check the terminals for corrosion (white or green crust), and confirm polarity: the flat negative end sits against the spring.

Install a fresh battery with correct polarity. If the contacts are corroded, scrub them with a pencil eraser first. A dead battery is one of the most common reasons an igniter won't spark.

  • Two-minute fix

    Fresh AA / AAA batteries

    If the igniter clicks but nothing sparks, or it's dead silent, a dead battery is the most common cause. Grab the size your igniter takes (check the compartment), install it with the flat end against the spring, and try again.

    See options on Amazon →

No battery compartment anywhere? You have a piezo igniter, a spring-loaded striker with no battery to swap. Skip to the electrode check.

Clean the electrode and check the gap

Clicks but no spark, or a weak spark that won't catch.

Deep dive

With the gas off and the tank valve closed, find the electrode. It is a small ceramic-and-metal probe just above or beside the burner. Look at the metal tip: grease, carbon, or rust will kill the spark, and a cracked ceramic collar will bleed it to ground.

Wipe the tip with a dry cloth, or a cotton swab with a little rubbing alcohol for baked-on grease, then let it dry fully before testing.

If your model uses a metal collector box behind the tip, the spark gap is typically small (often around 1/8 to 1/4 inch). Check your model's spec before adjusting. Make only small adjustments with the gas off: forcing the electrode can crack the ceramic.

Clear the burner ports

Sparks fine, smells gas, still no light? Look for a spider web.

Deep dive

Insects, mud daubers and spiders especially, nest inside burner tubes between cooks. Even a partial blockage stops gas from reaching the spark. With the gas off, pull the grates and heat tents and shine a flashlight through the burner ports; you should see light through the small holes.

The match test settles it: turn on one burner and hold a long lighter to the ports. If it lights with a match but not the igniter, your gas and burner are fine. The problem is the igniter system, not the gas path.

To clear a clog, turn the gas fully off and run a thin wire brush or stiff pipe cleaner through the ports and tube opening. Do not use water; it drives debris in. Do not use a toothpick that can snap off inside.

    Venturi / burner-tube cleaning brush

    A spider web or debris plug inside the burner tube blocks gas from reaching the spark. It's the most common non-obvious ignition failure. A long, thin brush clears it in a minute. No parts, no money beyond the brush.

Light it with a match as a backup

A workaround to keep cooking while you source parts. Not a permanent fix.

Deep dive

If the igniter is down, you can still cook safely. Open the lid fully first. Hold a lit long-handled lighter or match at the burner port, then turn on the gas. Never gas first, then flame. If it doesn't light in a few seconds, turn the gas off, wait at least a minute for it to clear, and try again. Never lean over the grill when lighting.

Keep it from happening again

Most burner clogs and fouled electrodes are a cleaning problem. A regular brush-down keeps gas flowing and the spark clean. We tested a bunch and found a brush that won't leave wire bristles in your food. Here's the one we trust.

Still no spark? Replace the igniter parts

You've confirmed the battery is fresh, the electrode is clean and intact, and gas is reaching the burner, but still nothing. Now it's worth replacing parts. Try the cheaper electrode first; replace the whole kit if that doesn't do it. Igniters aren't universal, so match any part to your grill's brand and burner count before ordering.

Own a Weber Spirit?

Igniter modules and electrodes are model-specific. For a Weber Spirit from the 2009-2012 generation, this genuine kit fits that model run exactly, with no universal guesswork. Check your model and year before ordering: it is scoped to the 2009-2012 Spirit generation.

Replace the part, or the grill?

If the igniter is the only problem, parts are inexpensive and the fix is quick. But if your grill also has rusted grates, a corroded burner, or a rusted-through firebox, you're past an igniter fix. Our full grill restore guide walks you through bringing it back to life, or knowing when to let it go.

FAQ

Why does my grill click but not light?

The igniter is sparking, but the spark isn't meeting gas where it needs to. The usual causes, in order: the regulator's safety bypass is limiting gas after a tank swap; a spider web or debris is blocking the burner ports; the electrode tip is fouled with grease or its gap is off; or the spark is grounding out before it can ignite. Work the supply, ports, and electrode steps above in that order.

There's no spark at all - the igniter doesn't even click. What's wrong?

Start with the battery. A dead or reversed battery is the most common cause of complete silence. If a fresh, correctly-installed battery doesn't bring the click back, check the igniter wire for damage or a short against the grill body. If the wire is fine, the module itself has likely failed and the kit replaces it.

My grill lights with a match but the igniter won't light it. What does that tell me?

Good news: your gas supply and burner are fine. The problem is entirely in the igniter system. Focus on the electrode tip, the spark gap, the igniter wire, and finally the module. Each is covered above, cheapest fix first.

I put in a new battery and it still won't spark. Now what?

A fresh battery rules out the most common cause but not all of them. Next, clean the battery contacts (a pencil eraser works), confirm polarity, then check the igniter wire for damage or contact with the grill body, inspect the electrode for cracks or heavy fouling, and confirm the spark gap is right. If all of that checks out, the module has failed and needs replacing.

My grill has gas but the flame is weak or yellow. Why?

Weak, lazy, or yellow flame on all burners after a tank swap usually points to the regulator's safety bypass. Run the full reset above. If it's still weak afterward, the regulator may be failing. Weak flame on just one burner more often means a clogged port on that burner.

Is it safe to light my grill with a match if the igniter doesn't work?

Yes, with care, and treat it as a temporary workaround rather than a fix. Open the lid fully first. Hold the lit match or a long lighter at the burner port, then turn on the gas. Never gas first. If the burner doesn't catch within a few seconds, shut the gas off, wait at least a minute for it to clear, and try again. Never lean over the grill while lighting.

It worked fine last summer. Why won't it start now?

Storage is hard on grills. The regulator's safety bypass often trips when you reconnect the tank, insects nest in the burner tubes over winter, and battery contacts corrode. Run the regulator reset first, then check the battery and look through the burner ports before assuming a part has failed.
