OEM Carrier Spark Electrode Ignitor (48VL400002 / 50HJ403022) for Model PY3GEAA48115AA

This OEM Carrier spark electrode ignitor is the factory-specified replacement for the Carrier PY3GEAA48115AA packaged gas/electric unit. The spark electrode ignitor generates the high-voltage arc that ignites the gas burner on each call for heat. When it fails or cracks, the control board will attempt ignition, detect no flame, and lock out the unit — leaving you with a no-heat call and a fault code. Replacing this ignitor with a genuine OEM assembly restores safe, reliable ignition from the very first cycle.

• OEM Part Numbers: 48VL400002 (original) | Current OEM successor: 50HJ403022 — direct factory replacement shipped as the authorized substitute. Cross-references: 50HJ401430, 50HJ400608.
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part. Generic electrodes often ship with incorrect rod gap, non-spec ceramic insulators, and undersized lead wire — all of which cause intermittent ignition, nuisance lockouts, and premature failure. OEM is the only choice for warranty-covered equipment.
• Install Difficulty: 2/5 — Disconnect power and shut off gas before starting. Tools needed: 1/4" and 5/16" nut drivers, flathead screwdriver, needle-nose pliers. Photograph the electrode orientation and wire routing before removal. Handle the ceramic insulator carefully — do not touch the electrode tip with bare hands. Re-gap is not required on OEM units.
• Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Engineered for the Carrier PY3GEAA48115AA packaged gas/electric rooftop unit. The successor part 50HJ403022 is the current shipping OEM replacement for discontinued 48VL400002. Always verify your unit's full model and serial number before ordering. Our fitment team is available to confirm compatibility before you purchase — no guesswork, no returns.
