Compatibility
This igniter button is compatible with some Weber grills. It is crucial to consult your grill's schematic or owner's manual to ensure this is the correct replacement part for your specific model. Incorrect part usage may lead to improper function or damage.
Setup and Installation
Before beginning installation, ensure your grill is turned off and completely cool. Disconnect the grill from its fuel source (e.g., propane tank or natural gas line).
- Locate the Existing Igniter: Identify the current igniter button and module on your Weber grill. This is typically found on the control panel.
- Remove Old Components: Carefully unscrew the retaining nut from the back of the existing igniter module. Disconnect any wires attached to the module. Remove the old igniter button and module from the grill.
- Install New Battery: Insert the provided AA Lithium battery into the new igniter module. Ensure the positive (+) and negative (-) terminals are aligned correctly. The module is designed for one AA battery.
- Position New Igniter: Insert the new igniter button and module assembly through the opening in the grill's control panel from the front.
- Secure with Nut: From the back of the control panel, thread the new retaining nut onto the igniter module and tighten it securely by hand. Do not overtighten.
- Connect Wires: Reconnect any ignition wires to the new module as per your grill's schematic. Ensure connections are firm.
- Test Functionality: Reconnect your grill to its fuel source. Press the igniter button to confirm a spark is generated at the burner electrodes.
