OEM Carrier Spark Electrode Ignitor 48VL400002 for Model PY4GEAB48130NA

This is the factory-specified OEM spark electrode ignitor assembly for the Carrier PY4GEAB48130NA packaged gas/electric unit. The spark electrode ignitor is a critical component in the burner ignition sequence — it generates the high-voltage spark that ignites the gas burner on each heating call. When the ignitor fails or becomes fouled, the control board will attempt ignition, fail to detect flame, and lock out the unit — leaving you with no heat and a blinking fault code. Replacing this OEM-matched assembly restores reliable ignition from the very first cycle.

• Part Numbers: OEM part number 48VL400002 | Current Carrier replacement cross-reference: 50HJ403022 | Genuine Factory Authorized Parts assembly
• OEM vs Generic: This OEM spark electrode assembly is built to exact Carrier factory specifications — correct electrode gap, bracket geometry, lead wire length, and ceramic insulator rating. Generic igniters often have inconsistent electrode gaps and inferior ceramic insulators, resulting in misfires, premature cracking, and repeat lockouts.
• Install Difficulty: 2/5 — Shut off gas supply and 24V power before beginning. Tools needed: 1/4" and 5/16" nut driver, needle-nose pliers. Photograph existing electrode orientation and wire routing before removal. Handle ceramic insulator with care — do not touch with bare hands, as skin oils can cause cracking under heat.
• Warranty & Shipping: 1-year OEM factory warranty against manufacturing defects. In stock and ships same business day from our warehouse.
