OEM Carrier Spark Electrode Ignitor 48VL400002 for Model PY4GNAB36060AA

This is the genuine OEM factory-specified spark electrode ignitor for the Carrier PY4GNAB36060AA packaged gas/electric unit. The spark electrode ignitor generates the precisely timed high-voltage spark that ignites the gas burner on every heating call. When this component fails, the control board will attempt ignition, detect no flame, and lock out the unit — leaving you with a system that tries to light but delivers no heat. Common symptoms include a no-heat lockout fault code, repeated ignition attempts with no burner response, or a visibly cracked or fouled electrode tip.

• Part Number: 48VL400002 (superseded by OEM cross-reference 50HJ403022) | Factory Authorized Carrier replacement part | Genuine OEM tolerances and materials
• OEM vs Generic: OEM spark electrode assemblies maintain exact gap geometry and ceramic insulator ratings engineered for this unit. Generic substitutes often use inferior ceramics prone to cracking under thermal cycling, leading to misfire and premature failure.
• Install Difficulty: 2/5 — Shut off gas supply and disconnect power at the breaker before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, and a flashlight. Photograph the electrode wire routing before disconnecting. Electrode gap is pre-set from the factory — do not bend the tip.
• Warranty: 1-year OEM factory warranty against manufacturing defects. In stock and ships same business day from our warehouse.
