Direct Replacement Ignition Cap

The NEX2797 electronic ignition cap replaces the original spark-generating component on compatible Nexgrill 720 and 730 series gas grills. It restores reliable piezo-electric starting without requiring tools beyond basic hand access. The part arrives new and ready to install.

Multi-Brand Compatibility Fit

This cap fits ten Jenn-Air models including 720-0339, 730-0164 and 730-0337, plus single models from BBQ-Pro (720-0266) and Charmglow (720-0304). The push-in mounting seats directly into the existing control panel cut-out, so no drilling or bracket modification is needed during replacement.

Piezo Ignition System Limits

The cap operates within a mechanical piezo-electric circuit that depends on a sharp impact to generate spark voltage. Moisture ingress, electrode wear or a weakened spring can prevent ignition even with a new cap installed. If the NEX2797 is unavailable, the NEX3582 (product 55072310) serves as an aftermarket alternative.
