OEM Carrier Spark Electrode Ignitor 48VL400002 for Model PY4GPAA48130AA

This OEM spark electrode ignitor (part number 48VL400002, superseded by 50HJ403022) is the factory-specified replacement ignition component for the Carrier PY4GPAA48130AA packaged gas unit. The spark electrode generates the high-voltage arc that ignites the gas burners on each call for heat. When it fails or becomes fouled with carbon deposits, the control board will attempt ignition, fail to detect a flame, and lock out the system — leaving you with no heat and a blinking fault code on the control board.

• OEM Part Numbers: 48VL400002 (original) | Superseded by 50HJ403022 — both are factory-authorized Carrier components engineered to identical specifications for the PY4GPAA48130AA
• OEM vs Generic: OEM spark electrodes maintain precise gap geometry and high-temperature ceramic insulator ratings. Off-brand electrodes often have inconsistent gap tolerances, leading to weak or erratic arcing, repeated ignition lockouts, and premature failure under thermal cycling.
• Install Difficulty: 3/5 — Shut off gas supply and 120V power before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, and a multimeter to verify ignitor continuity. Disconnect the high-voltage wire carefully and avoid touching the electrode tip — skin oils can cause ceramic cracking under heat. Photograph wiring before removal.
• 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 as a direct OEM replacement for the Carrier PY4GPAA48130AA packaged gas/electric unit. Note that 48VL400002 has been superseded by Carrier part 50HJ403022 — both are genuine Carrier components and are functionally identical. Verify your unit's data plate before ordering.
