OEM Carrier Spark Electrode Ignitor Assembly for Model PY3GNA060115AB

This OEM Carrier spark electrode ignitor assembly is the factory-specified replacement for the Carrier PY3GNA060115AB packaged gas unit. The ignitor generates the high-voltage spark that ignites the gas burner during each heating cycle. When it fails, the control board will attempt ignition, detect no flame, and lock out — leaving you with a system that blows cold air or no air at all. Common symptoms include a furnace that attempts to start then shuts down, a fault code indicating ignition failure, or repeated short cycling with no heat output.

• OEM Part Numbers: 48VL400002 (Spark Electrode Ignitor) | 48GS400168 (Spark Electrode Ignitor, 2-Rod Assembly) — both are factory-authorized Carrier ignitor assemblies for this model. Note: 48VL400002 has been superseded by Carrier part 50HJ403022; our listing covers factory-equivalent OEM fitment.
• OEM vs Generic: Genuine Carrier OEM ignitor assemblies are built to exact electrode gap, ceramic insulator grade, and wire harness specifications. Off-brand electrodes often use inferior ceramic materials that crack under thermal cycling, leading to repeat failures and potential nuisance lockouts.
• Install Difficulty: 2/5 — Shut off gas supply and disconnect power before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, a multimeter for continuity verification. Photograph existing electrode orientation and wire routing before removal. Avoid touching the ceramic insulator — skin oils accelerate cracking at high temperatures.
• Warranty: 1-year OEM factory warranty against manufacturing defects. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PY3GNA060115AB packaged gas/electric rooftop unit. Verify your unit's data plate and existing part number before ordering — the PY3GNA060115AB uses a 2-rod spark electrode ignitor configuration. Questions about fitment?
