OEM Carrier Spark Electrode Ignitor (2-Rod) for Model PY3GNA048115AB

This OEM spark electrode ignitor assembly is the factory-specified replacement for the Carrier PY3GNA048115AB packaged gas unit. The ignitor generates the high-voltage spark that lights the gas burners at each ignition cycle. When the electrode assembly fails, the unit will attempt ignition, fail to establish flame, and lock out — leaving you with no heat. Replacing this part with an OEM assembly restores factory-precise spark gap geometry and arc reliability.

• OEM Part Numbers: 48GS400168 (primary, active) | 48VL400002 (superseded, cross-reference) | Successor: 50HJ403022 — all are factory-authorized for this application. 2-rod electrode assembly with integrated wiring harness and mounting bracket.
• OEM vs Generic: OEM electrode assemblies maintain exact spark gap tolerances, correct ceramic insulator grade, and matched connector pinout. Generic igniters frequently use off-spec gap widths that cause intermittent ignition failures and accelerated carbon fouling on the burner.
• Install Difficulty: 2/5 — Turn off gas supply and 24V control power before servicing. Tools needed: 1/4" nut driver, flat-blade screwdriver, needle-nose pliers. Disconnect the high-voltage lead and mounting screws, swap the electrode assembly, and confirm wire harness seating before restoring power. Photograph original wiring orientation before disconnecting.
• Warranty: 1-year OEM factory warranty against manufacturing defects. Ships same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Engineered for the Carrier PY3GNA048115AB packaged gas/electric rooftop unit. Verify your unit's model and serial data plate before ordering.
