OEM Carrier Spark Electrode Ignitor Assembly (48VL400002) for Model PY3GPAA48130NA

This is the factory OEM spark electrode ignitor assembly for the Carrier PY3GPAA48130NA packaged gas/electric unit. The ignitor is the first component to fire during every heat call — it generates the high-voltage spark that lights the burner. When it fails or degrades, the unit enters ignition lockout, the control board trips a fault code, and your system stops producing heat entirely. Replacing the ignitor is one of the most common and cost-effective furnace repairs available.

• Part Numbers: OEM part 48VL400002 (Spark Electrode Ignitor) | Current superseding OEM replacement: 50HJ403022 — both are factory-authorized for this application.
• OEM vs Generic: OEM electrode assemblies are manufactured to exact gap spacing, ceramic insulator grade, and wire harness length specified by Carrier engineering. Aftermarket igniters often deviate on electrode gap or insulator quality, leading to intermittent sparking, premature cracking, and repeat failures within one season.
• Install Difficulty: 2/5 — A straightforward swap requiring a 1/4" nut driver, needle-nose pliers, and a phone camera to document wire routing before disconnecting. Always shut off gas supply and 24V control power before beginning. Avoid touching the ceramic electrode body with bare hands — skin oils accelerate cracking under heat cycling.
• Warranty: 1-year OEM manufacturer warranty against defects. Orders placed before 2:00 PM local time ship same business day from our warehouse.

Compatibility: Engineered as the direct OEM replacement for Carrier PY3GPAA48130NA packaged rooftop/gas-electric units. Also fits additional 48-series and PY-series Carrier commercial packaged models that originally specified part number 48VL400002 or 50HJ403022. Always verify your unit's data plate and existing ignitor part number before ordering — our team is available to confirm fitment at no charge.
