Most likely causes (in order)

Fix 1: Check the propane tank

Most common cause. Even a tank that looks half-full can be too low to feed all burners under load.

1. Weigh the tank – empty is 17-18 lb, full is 37-38 lb.
2. Verify tank valve is fully open (turn counter-clockwise until stop).
3. If low, swap for a full tank.
4. Consider a spare tank always on hand.

Replacement parts and tools that fix this:

• Flame King 20 lb Propane Tank — Spare tank for swap-out.
• DOZYANT Propane Tank Gauge — Shows tank level at a glance.

Fix 2: Reset the regulator (bypass mode)

If the regulator senses a rapid drop in pressure (like opening the tank valve fully with the grill on), it goes into bypass mode. This gives low flames on all burners.

1. Turn OFF all grill knobs.
2. Turn OFF tank valve.
3. Disconnect the regulator from the tank.
4. Wait 30 seconds.
5. Reconnect the regulator.
6. Turn tank valve slowly to open (one turn).
7. Wait 30 seconds. Now try to light.

Replacement parts and tools that fix this:

• DOZYANT Propane Regulator with Hose — Replacement regulator if reset fails.
• Universal 3ft Propane Regulator Hose — Alternative regulator.

Fix 3: Replace igniter batteries or electrode

Battery igniters need fresh AA/AAA batteries. Piezo igniters wear out and need replacement.

1. Locate the igniter battery compartment (usually behind a knob).
2. Replace with fresh batteries.
3. If click but no spark: replace the electrode.
4. If no click at all: replace the igniter module.

Replacement parts and tools that fix this:

• Weber Grill Igniter Replacement — Weber-compatible igniter.
• Universal Grill Igniter Kit — Universal igniter replacement.
• Duracell AA Batteries 20-Pack — Igniter batteries.

Fix 4: Clean the burner tubes

Debris in the burner ports blocks gas flow to individual ports. Uneven flames = clogged burner.

1. Cool the grill completely.
2. Remove grates and heat plates.
3. Use a wire brush along the burner tubes to clear ports.
4. Vacuum out debris.
5. If badly corroded, replace burner tubes.

Replacement parts and tools that fix this:

• Weber Gas Grill Burner Tube Replacement — Weber burner replacement.
• Char-Broil Burner Tube Replacement Kit — Char-Broil burner replacement.

Fix 5: Clear spider webs from venturi tubes

Spiders and small insects nest in venturi tubes during off-season. This is extremely common after winter storage.

1. Remove burner tubes carefully.
2. Look inside each venturi tube for webs or debris.
3. Clean with a pipe cleaner or venturi brush.
4. Reinstall.
5. Prevent by covering the grill when not in use.

Replacement parts and tools that fix this:

• Char-Broil Venturi Tube Brush — Cleans venturi tubes safely.
• Classic Accessories Grill Cover — Prevents insect nesting during storage.
