AOG 24-B-04T T-Series Main Burner Igniter Assembly

What Problem This Part Solves

Ignition electrodes operate close to the burner and are continually exposed to heat, grease, moisture, food residue, and outdoor conditions. Over time, contamination, corrosion, cracked ceramic insulation, or electrode deterioration can prevent a reliable ignition spark.

Replacing the 24-B-04T may correct:

• Main burner that will not ignite
• Weak or inconsistent ignition spark
• Cracked ceramic electrode insulator
• Corroded or damaged electrode
• Damaged ignition wire
• Deteriorated flash tube
• Intermittent burner ignition
• Igniter that works only after repeated attempts

Before replacing the assembly, check that the electrode and surrounding area are clean and properly positioned.

Compatibility / Fits Models

AOG 24-B-04T is listed for T-Series 24", 30", and 36" grills, including compatible built-in and portable configurations. AOG's parts documentation specifies the following quantities:

Replacement-parts documentation further identifies 24-B-04T with T-Series grills manufactured from approximately 2014 forward that use the flame-thrower valve ignition system.

Examples of T-Series applications listed by parts references include 24NBT, 24NGT, 24PCT, 30NBT, 30PCT, 36NBT, and 36PCT configurations.

Fits most grills within this series—confirm model number before ordering.

Important: 24-B-04T vs. 24-B-51T

These two parts work together but are not the same replacement:

• 24-B-04T – Main burner igniter/electrode assembly only
• 24-B-51T – Main burner valve with igniter assembly

AOG's factory parts diagram lists both components separately.

If the gas valve itself is functioning correctly but the electrode, ceramic insulator, wire, or flash tube is damaged, 24-B-04T allows the ignition portion to be replaced without replacing the entire 24-B-51T valve assembly.

Important: 24-B-04T vs. 24-B-04

AOG also distinguishes between these two ignition components:

• 24-B-04T – Main burner electrode/igniter assembly for T-Series
• 24-B-04 – Main burner electrode for L-Series and pre-2015 applications

AOG's current replacement-parts catalog lists these separately, so the suffix “T” is important when identifying the correct replacement.

Installation / Use Instructions

1. Turn off the gas supply and allow the grill to cool completely.
2. Access the affected main burner valve and remove the existing electrode/flash-tube assembly, noting the original wire routing and mounting position.
3. Install the new 24-B-04T assembly, reconnect the ignition wire, and verify that the electrode and flash tube are properly positioned before testing ignition.

If any gas-system connections are disturbed during service, perform an approved leak test before operating the grill. Never use an open flame to check for gas leaks.

How many 24-B-04T igniters does my grill use?
AOG specifies 2 for 24" grills, 3 for 30" grills, and 3 for 36" grills. The replacement assembly is sold individually.

Is 24-B-04T the same as 24-B-51T?
No. 24-B-04T is the igniter assembly only, while 24-B-51T is the complete main burner valve with igniter assembly.

Is 24-B-04T the same as AOG 24-B-04?
No. AOG identifies 24-B-04T for T-Series grills, while 24-B-04 is designated for L-Series and pre-2015 applications.
