Quick Answer
If your Gas Grill 4 Burner Won’t Light, the most common cause is a dead AA battery in the push button igniter or a weak spark that cannot reach the gas. Try replacing the battery first, then check that you hear a clicking sound and see a spark at each electrode while the gas is off. If you get spark but no flame, the issue is usually gas flow or dirty burner ports.
Why This Happens
Four burner grills use a single spark generator with four outlets, one wire to each burner. When the battery is weak, corroded, or installed incorrectly, the module cannot send a strong spark to any burner. Moisture, grease, and corrosion at the electrode tip also prevent the spark from jumping.
Gas flow problems are another frequent cause. If the propane tank valve was opened too quickly, the regulator can go into bypass and limit flow. A nearly empty tank, a kinked hose, or spider webs and grease inside the venturi tubes can also block gas from reaching the burner.
Dirty burner ports stop ignition even when spark and gas are present. Grease, rust, and food debris clog the small holes along the burner tube, so the gas cannot exit where the spark occurs. This is common after a season of heavy use or if the grill was stored uncovered.
Wiring issues can affect all four burners at once. A loose ground wire, a cracked ceramic electrode, or a wire that has melted against a hot surface will interrupt the circuit. If one wire is damaged, the spark may leak before it reaches the tip, and none of the burners will light reliably.

Fixes to Try
Work through these steps in order, easiest first, with the gas off until you are ready to try lighting. Always turn the knobs off and close the tank valve before inspecting parts.
- Replace the igniter battery and check the spark. Unscrew the push button cap, remove the old AA battery, and install a fresh one with the correct polarity. Press the button and look for a bright blue spark at each electrode, you should also hear a rapid clicking sound.
- Reset the regulator and confirm gas flow. Turn all burner knobs off, close the tank valve, disconnect the regulator, wait a minute, then reconnect. Open the tank valve slowly, then try to light one burner with the lid open. If you smell gas but get no flame, flow is likely okay and the issue is spark or ports.
- Clean the electrodes and burner ports. Brush the electrode tip gently with a dry toothbrush to remove grease and corrosion, and make sure the ceramic is not cracked. Clear the burner port holes with a soft brush or pipe cleaner, and check the venturi tubes for webs or debris.
- Inspect wires and connections. Follow each thin wire from the spark generator module to the electrode and look for loose plugs, melted insulation, or contact with metal. Push each connector firmly onto its terminal and reposition any wire that touches the firebox.
- Try manual lighting to isolate the problem. With the lid open, turn one burner to high, then use a long grill lighter at the burner edge. If it lights manually but not with the push button, the spark system is the culprit. If it will not light manually either, focus on gas supply and port cleaning.

When to Consider Replacing It
If the battery is fresh, wires are secure, ports are clean, and you still get no spark at any of the four burners, the spark generator module itself has likely failed. Corrosion inside the module, a worn push button, or internal damage from moisture often means replacement is more practical than further cleaning. If you would rather replace it than keep troubleshooting, a universal 4 outlet module that fits many Char-Broil and similar 4 burner models is a common option.

When choosing a replacement, confirm your grill model number and the mounting hole size, and remember an AA battery is typically required but not included. A direct fit module can restore push button ignition without modifying the control panel.
When to Skip This and Call a Professional
This DIY troubleshooting is not ideal for gas leaks, damaged gas lines, or a regulator that hisses continuously. If you smell strong gas with knobs off, see bubbles at connections during a soapy water check, or suspect the hose or manifold is cracked, skip this and contact a licensed technician or your gas supplier. Working on pressurized fuel components is not recommended for home repair and is not the right choice when safety controls may be involved.

Frequently Asked Questions
Why does my Gas Grill 4 Burner Won’t Light even though I hear clicking?
Hearing clicks means the module has power, but the spark may be weak or misdirected. Check for a low battery, corrosion on the electrode tip, or a wire that is grounding against metal before it reaches the burner.
Why will only one burner light on my 4 burner grill?
One burner lighting while others do not often points to clogged ports or a single bad electrode wire on the non lighting burners. Clean that burner’s ports and inspect its wire and electrode, then try lighting it manually to confirm gas is flowing.
Do I need to turn the propane tank on slowly every time?
Opening the valve slowly helps prevent the regulator from entering bypass mode, which can restrict gas flow and prevent lighting. If you opened it quickly and now have weak flames or no ignition, try the regulator reset described above with all knobs off.
