Gas Grill Troubleshooting Guides
Most gas grill problems are fixable without a new grill. These guides diagnose ignition failures and burners that die, with free fixes first before any parts are needed.

Gas grill won't ignite
Every fix from a wet igniter to a dead module, so you are cooking again today.

Gas grill burner won't stay lit
Flame lights but dies? Regulator resets, clogged ports, and when to replace the part.

Gas grill flare-ups
Flare-ups come from grease, not gas. Free fixes first, then parts only if bars are warped through.

Gas grill heats unevenly
Hot spots and cold zones traced to clogged ports, worn flavorizer bars, or a stuck regulator.

Propane grill not getting hot enough
When all burners run low, the regulator bypass is the top suspect. The reset takes two minutes.

Gas grill burning yellow or orange
Yellow flame means incomplete combustion. Spider nests in venturi tubes are the top cause, and clearing them costs nothing.

Gas grill temperature will not come down
A grill running too hot is usually a grease fire, a faulty control valve, or a misleading lid thermometer. Safety check first.

One side of the grill not working
A single dead burner almost always traces to a spider nest or clogged ports on that burner, not the regulator.

FAQ
A burner that lights but dies mid-cook usually points to one of three causes: a regulator in bypass mode (reset it by turning off the gas, disconnecting the hose for 30 seconds, then reopening the valve slowly), clogged burner ports (clean them with a stiff wire or pin), or low propane flow. If only one burner dies while others stay lit, the problem is almost always clogged ports on that specific burner, not the regulator.
Yellow or orange flames mean incomplete combustion — the burner is not getting enough air mixed with the gas. The most common culprit is a spider nest or debris blocking the venturi tubes (the air-intake openings at the back of the burner). Clear the blockage with a flexible venturi brush or a pipe cleaner. If the flames are still yellow after cleaning, the air shutter on the burner tube may need adjustment.
Turn all burner knobs to OFF, then close the tank valve. Disconnect the regulator from the tank and wait 30 seconds for the pressure to equalize. Reconnect the regulator, then open the tank valve slowly — all the way — and wait another 30 seconds before lighting any burner. This clears the bypass mode that the regulator trips into when it detects a sudden pressure drop, which is a common reason a grill runs at a fraction of full heat.
A single dead burner while the others run normally is almost always a clogged burner tube on that side, not a regulator or tank problem. Turn off the grill, let it cool, then remove the grates and Flavorizer bars over the dead burner. Look through the ports for spider nests or carbon buildup and clear them with a stiff wire or venturi brush. If the ports are clear and the burner still does not light, the igniter electrode for that burner may be cracked or corroded.
