OEM Carrier Spark Electrode Ignitor (48VL400002) for Model PY3GNA048130AA

This OEM spark electrode ignitor is the factory-specified replacement for the Carrier PY3GNA048130AA packaged gas unit. The spark electrode ignitor generates the high-voltage electrical arc that ignites the gas burner on each heating call. When it fails, the control board typically attempts ignition one to three times before locking out — leaving you with no heat and a fault code on the board. Common failure signs include visible cracking of the ceramic insulator, carbon tracking on the electrode tip, or a bent/broken ground rod that prevents proper spark gap.

• OEM Part Number: 48VL400002 (superseded to 50HJ403022) | Factory Authorized Carrier replacement | L-shaped electrode design | 2¾" total length | Made in USA
• OEM vs Generic: OEM electrodes are manufactured to exact spark-gap tolerances and ceramic insulator ratings. Off-brand electrodes often vary in gap distance and insulator grade, leading to intermittent ignition failures and repeat service calls.
• Install Difficulty: 2/5 — Shut off gas and 24V power before servicing. Tools needed: ¼" hex driver, needle-nose pliers, and a multimeter to verify igniter continuity. Always inspect the ignition wire and boot for cracks before reinstalling the access panel.
• Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PY3GNA048130AA packaged gas/electric unit. OEM part 48VL400002 is superseded by Carrier part 50HJ403022 — both are acceptable factory replacements. Verify your existing electrode's mounting bracket style and spark-gap orientation against your unit's wiring diagram before ordering. Our fitment team is available to confirm compatibility before you buy.
