Replacement Switch Assembly for Summit Grills

The Weber 42053 3GN switch assembly is a four-piece aftermarket component designed to replace the original ignition switch on compatible Summit gas grills. It fits 123 listed Weber Summit models produced between 2003 and 2006, including Platinum, Gold, and Silver series in both natural gas and LP configurations. The part also fits the Turbo brand model XG6THSSN. This new component restores ignition function when the factory switch fails.

Four-Piece Kit Simplifies Repair

The assembly includes four individual pieces that together form the complete switch mechanism, allowing a full replacement rather than a partial fix. Because the original Weber part is discontinued, this aftermarket version provides the only practical way to bring ignition back to the listed grills without fabricating custom parts. No additional software, wiring harnesses, or mounting brackets are included or required beyond what the original grill already provides.

Straightforward Installation With Common Pitfalls

Installation typically involves removing the control panel fascia, disconnecting the old switch wires, and connecting the new assembly in the same positions. The most frequent issue is misidentifying the correct terminal for each wire, which can prevent spark generation or cause a short. Verifying the grill model number against the 123 compatible codes before ordering avoids fitment problems on similar-looking but unsupported Summit variants.
