OEM Carrier Spark Electrode Ignitor Assembly (48VL400002) for Model PY4GNAA30060AA

This is the factory OEM spark electrode ignitor assembly for the Carrier PY4GNAA30060AA packaged gas unit. The ignitor generates the high-voltage spark arc that ignites the gas burner on every call for heat. When this component fails, the control board will attempt ignition, detect no flame, and lock out the unit — leaving you with a system that runs the inducer but produces no heat. Fault codes for ignition failure or repeated lockout are the most common diagnostic signal that this part needs replacement.

• Part Numbers: OEM part 48VL400002 (superseded by Carrier 50HJ403022) | Both numbers are factory-authorized for this application | Country of Origin: USA
• Physical Specs: L-shaped spark electrode ignitor | Ignitor length to L: 1⅜" | Total ignitor length: 2¾" | Ground lead length to L: 2 1/16" | Ground total length: 4" | Bracket length: 1⅝" | Includes spark electrode and bracket assembly
• OEM vs Generic: OEM electrodes maintain precise tip gap geometry and use high-temperature ceramic insulators to factory specification. Generic electrodes often have inconsistent tip gaps, leading to intermittent ignition, nuisance lockouts, and shortened service life.
• Install Difficulty: 2/5 — Shut off gas supply and disconnect power before servicing. Tools needed: ¼" and 5/16" nut drivers, needle-nose pliers. Disconnect ignitor wire lead, remove mounting screws, swap electrode, confirm tip gap is aligned to burner. Always verify ignitor wire boot is fully seated after installation.
• Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse.
