OEM Carrier Spark Electrode Ignitor 48VL400002 for Model PY4GNAB48130NA

This OEM Carrier spark electrode ignitor (part number 48VL400002, superseded by 50HJ403022) is the factory-specified replacement for the Carrier PY4GNAB48130NA packaged gas/electric unit. The spark electrode ignitor generates the high-voltage electrical arc that ignites the gas burner at the start of every heat cycle. When it fails or cracks, the control board will attempt ignition, detect no flame, and lock out the system — leaving you with a unit that blows cold air or shuts down entirely after a brief startup attempt.

• Part Numbers: OEM part 48VL400002 | Current superseding OEM part: 50HJ403022 | Factory-authorized direct replacement — no modifications required
• OEM vs Generic: OEM spark electrodes are precision-gapped and rated to factory specifications for arc voltage and ceramic insulator integrity. Generic igniters often use inferior ceramic insulators prone to early cracking, risking carbon tracking and ignition failure under thermal cycling.
• Install Difficulty: 2/5 — Turn off gas supply and disconnect power before servicing. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, work gloves. Photograph the electrode orientation and wiring harness routing before removal. Handle the ceramic body carefully — do not touch the tip with bare hands.
• Warranty: 1-year OEM factory warranty against manufacturing defects. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Designed for the Carrier PY4GNAB48130NA packaged unit. Note that OEM part 48VL400002 has been officially superseded by Carrier part 50HJ403022 — both are fully interchangeable and meet identical factory specifications. Verify your unit's data plate and existing electrode configuration before ordering. Our fitment team is available to confirm compatibility before you buy.
