How to Replace a Bull BBQ Igniter
A failed Bull ignition module replaces in 15 minutes with a Phillips driver. The hard part is identifying the correct service part for your specific model — Bull uses different modules for push-button piezo vs electronic battery-powered systems.

Step by step
Shut off gas + disconnect the regulator
Close the gas supply valve, then disconnect the regulator from the tank (LP) or the sediment-trap union (NG). No gas should reach the grill during the swap.
Remove the grates, flame tamers, and burner tubes
Full access to the electrodes requires clearing the cook box. Remove grates, flame tamers, then the burner tubes (Phillips at each valve end). Set aside in the order you removed them for reassembly.
Identify your igniter module type
Push-button piezo = silver cylinder with a plunger mounted behind the control panel. Battery electronic = black plastic module with battery compartment. Match your replacement part to this type — not interchangeable.
Remove the old module
Push-button: unscrew the retaining nut behind the panel, pull the module out. Electronic: open battery compartment, remove battery, then the 4 mounting screws on the back of the module.
Disconnect the electrode wires
Each burner has an electrode wire running from the module to a ceramic electrode at the burner-tube end. Note which wire goes to which burner before disconnecting (color codes or marking tape help).
Install the new module + reconnect electrode wires
Reverse the removal sequence. Snug each electrode wire connector onto its spade; verify the ceramic electrode seats correctly at the burner-tube opening (1/8-inch to 3/16-inch gap from the burner metal is Bull's spec).
Reassemble + test
Reinstall burner tubes, flame tamers, grates. Reconnect gas, open the main valve, press ignition — each burner should fire within 3 seconds.
Common mistakes
- Installing the wrong module type. Piezo and electronic modules are physically different. Confirm your original before ordering the replacement.
- Over-torquing the electrode-wire spade connectors. Hand-tight is correct. Pliers bend the spade and break the connection.
- Leaving the electrode gap wrong. Too close = no spark. Too far = weak spark. 1/8" to 3/16" from the burner metal is the sweet spot.
Hands-on tips
- Keep a spare AA battery with the grill. 90% of 'ignition failure' calls are the battery, not the module.
- Photograph the electrode-wire routing before disconnecting. Reassembly in the correct order takes 1 minute vs 10 if you have to figure it out.
- Order the module from Bull's authorized parts channel (pitboss-free aftermarkets are hit-or-miss on fit).
Questions people ask
Can I use an aftermarket igniter module?
Bull's warranty requires OEM parts for ignition. Aftermarkets may fit but void warranty and can void gas-certification on the grill.
How long does a Bull ignition module last?
5-7 years typical, longer if the grill is covered and stored dry. Humid storage + salt air (coastal installs) shortens life.
