A gas grill that will not light is almost always propane, regulator, igniter, or burner.
This guide walks you through the checks in order of likelihood, from the tank to the burner tubes. Most fixes cost under $30.

Most likely causes (in order)
- Empty or nearly-empty propane tank — Regulator hisses briefly then nothing; flame will not sustain.
- Regulator stuck in bypass mode — Very low flames on all burners even with tank full.
- Failed igniter (battery or piezo) — Click sound but no spark, or no click at all.
- Clogged burner tubes — Uneven flames, some ports lit and others dark.
- Spider or insect blockage in gas line — Very weak flame after seasonal storage. Common in humid climates.
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.
- Weigh the tank – empty is 17-18 lb, full is 37-38 lb.
- Verify tank valve is fully open (turn counter-clockwise until stop).
- If low, swap for a full tank.
- Consider a spare tank always on hand.

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.
- Turn OFF all grill knobs.
- Turn OFF tank valve.
- Disconnect the regulator from the tank.
- Wait 30 seconds.
- Reconnect the regulator.
- Turn tank valve slowly to open (one turn).
- Wait 30 seconds. Now try to light.

Fix 3: Replace igniter batteries or electrode
Battery igniters need fresh AA/AAA batteries. Piezo igniters wear out and need replacement.
- Locate the igniter battery compartment (usually behind a knob).
- Replace with fresh batteries.
- If click but no spark: replace the electrode.
- If no click at all: replace the igniter module.

Fix 4: Clean the burner tubes
Debris in the burner ports blocks gas flow to individual ports. Uneven flames = clogged burner.
- Cool the grill completely.
- Remove grates and heat plates.
- Use a wire brush along the burner tubes to clear ports.
- Vacuum out debris.
- If badly corroded, replace burner tubes.
