OEM Carrier Spark Electrode Ignitor for Model PY4GPAB60090NA (48VL400002 / 50HJ403022)

This is the factory-authorized OEM spark electrode ignitor assembly for the Carrier PY4GPAB60090NA packaged gas unit. The spark electrode is the first component in the ignition sequence — it generates the high-voltage spark that lights the burner. When this part fails or cracks, the control board will attempt ignition, detect no flame, and trigger a safety lockout. Common symptoms include: no heat, repeated ignition attempts followed by a fault code, or a furnace that cycles on and off without ever establishing a flame.

• OEM Part Numbers: 48VL400002 (original) | Superseded by 50HJ403022 — both are factory-authorized Carrier parts. This listing ships the current production version.
• Specs: Spark electrode style — L-shaped | Total length: 2¾" | Country of origin: USA | Factory-matched gap and ceramic insulator for reliable arc generation
• OEM vs Generic: OEM electrodes maintain exact gap geometry and ceramic grade specified by Carrier engineering. Off-brand electrodes often use inferior ceramics that crack under thermal cycling, causing repeat no-heat calls.
• Install difficulty: 2/5 — Shut off gas and power before starting. Tools needed: 1/4" nut driver, needle-nose pliers, phone camera (photograph wire connections before removal). Handle the ceramic tip carefully — do not touch with bare hands. Reconnect ignition wire and ground lead securely before restoring power.
• Warranty: 1-year OEM factory warranty against manufacturing defects. In stock — ships same business day from our warehouse.
