OEM Carrier Spark Electrode Ignitor Assembly 48VL400002 for Model PY3GNAA60115NA

This OEM Carrier spark electrode ignitor assembly is the factory-authorized replacement for the Carrier PY3GNAA60115NA packaged gas unit. The spark electrode ignitor generates the high-voltage spark that lights the burner during each heating cycle. When it fails or cracks, the control board will attempt ignition, detect no flame, and lock out the system — leaving you with a cold unit and a fault code. Replacing the ignitor is one of the most common and cost-effective furnace repairs available.

• Part Numbers: OEM part 48VL400002 (superseded by 50HJ403022) | L-shaped spark electrode design | Country of Origin: USA | Bracket included
• OEM vs Generic: This is a genuine Carrier Factory Authorized Parts ignitor, matched to exact gap spacing and ceramic insulator specs for the PY3GNAA60115NA burner assembly. Off-brand igniters can produce inconsistent spark timing, leading to repeated lockouts and premature heat exchanger stress.
• Install Difficulty: 2/5 — Shut off gas and 24V power before servicing. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Disconnect the spark wire lead, remove the single mounting screw, and swap the electrode. Do not touch the ceramic tip with bare hands — skin oils reduce spark efficiency.
• Warranty: 1-year OEM factory warranty against manufacturing defects. Ships same business day from our stocked warehouse.

Compatibility: Designed for the Carrier PY3GNAA60115NA packaged rooftop gas/electric unit. Note: OEM part number 48VL400002 has been superseded by Carrier part 50HJ403022 — both are fully interchangeable and this listing ships the current production replacement.
