Clean versus clogged burner ports Left tube shows even open ports and a blue flame sketch. Right tube shows grease-clogged ports and a yellow uneven flame. BURNER TUBE · PORTS CLEAN Even blue cones. Every port open. CLOGGED Grease in the holes. Yellow, lift, dead spots. Ream with a bit smaller than the port. Do not drill oversized. Brass brush the row. Keep liquid out of the venturi / inlet. If the tube wall is lace under the ports, replace the set — do not patch holes.

Replace Char-Broil burner tubes

Pull stamped Char-Broil tubes, match length and inlet, reseat on the orifices, and leak-check. Universal tubes that are short are how flashbacks start.

Replace Char-Broil heat plates

Measure tent length and width on Performance and Commercial carts. Heat plates are the drip shields — when they lace, burners die. Do not buy by lid name alone.

Char-Broil igniter replacement

Box-store Char-Broil Performance and Commercial carts: piezo versus AA collector, electrode clips on stamped burners, and why the side burner is a separate lead.
