OEM Carrier Spark Electrode Ignitor 48VL400002 for Model PY4GPAB36090NA

This OEM spark electrode ignitor assembly is the factory-specified replacement for the Carrier PY4GPAB36090NA packaged gas unit. The ignitor generates the high-voltage spark that ignites the gas burners on each call for heat. When this component fails, the unit will attempt ignition, fail to establish flame, and enter a safety lockout — leaving you with no heat and a blinking fault code. OEM part number 48VL400002 has been superseded by Carrier's current production part 50HJ403022, which is a direct, factory-authorized replacement shipped in its place.

• Specs: Spark electrode ignitor assembly | Superseded OEM P/N: 48VL400002 | Current OEM P/N: 50HJ403022 | Factory-authorized Carrier/Bryant/Payne replacement | Includes electrode and bracket assembly (wire harness sold separately)
• OEM vs Generic: This is a genuine OEM Carrier ignitor, manufactured to exact factory spark-gap and ceramic insulator tolerances. Off-brand igniters may have inconsistent spark timing or substandard ceramic insulators that crack under thermal stress, leading to repeat failures and nuisance lockouts.
• Install difficulty: 2/5 — Turn off gas supply and 24V control power before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Photograph the original electrode orientation and wire routing before removal. Handle ceramic insulator with care — do not touch the electrode tip with bare hands, as skin oils can cause premature failure.
• Warranty: 1-year OEM factory warranty against manufacturing defects. Ships same business day from our warehouse.
