OEM Carrier Spark Electrode Ignitor 48VL400002 for Model PY4GPAA42060AA

This OEM spark electrode ignitor is the factory-specified replacement for the Carrier PY4GPAA42060AA packaged gas/electric unit. The spark electrode ignitor generates the high-voltage spark that ignites the gas burner at the start of each heating cycle. When it fails, the control board will attempt ignition, fail to detect a flame, and enter a hard lockout — leaving you with a system that blows cold air or shuts down entirely with an ignition fault code. OEM part number 48VL400002 has been superseded by Carrier's updated replacement 50HJ403022, and our listing ships the current factory-authorized successor part.

• Specs: Spark electrode ignitor assembly | Factory-authorized OEM replacement | Includes electrode rod, mounting bracket, and ignition wire lead | Replaces 48VL400002, 50HJ401430, 50HJ400608
• OEM vs Generic: OEM electrodes are manufactured to exact gap geometry and ceramic insulator specifications. Off-brand electrodes can produce inconsistent spark arcs, cause nuisance lockouts, and accelerate control board wear over time.
• Install difficulty: 2/5 — Shut off gas supply and 24V control power before servicing. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Note electrode tip gap and orientation before removal. Avoid touching the ceramic insulator — oil from skin can cause cracking under heat.
• Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Designed for the Carrier PY4GPAA42060AA packaged rooftop gas/electric unit. OEM part 48VL400002 is discontinued and superseded — we ship the current Carrier-authorized successor (50HJ403022) for guaranteed fitment. Verify your unit's data plate model number before ordering. Our team is happy to confirm compatibility before you buy.
