OEM Carrier Spark Electrode Igniter Assembly (50HJ403022) for Model PY1RPA120180ABWA

This is the genuine OEM spark electrode igniter assembly for the Carrier PY1RPA120180ABWA gas-fired packaged unit. The igniter assembly initiates combustion each time the system calls for heat — when it fails, the control board will attempt ignition, find no flame signal, and lock out the system, leaving you with no heat. Common symptoms include the inducer starting normally, a brief spark attempt, then a fault lockout code indicating ignition failure.

• Specs: 2-rod spark electrode assembly with mounting bracket | Ceramic-body construction | Replaces legacy OEM part 48VL400002 | Approximately 4.25″ L × 2.95″ W × 1.75″ H | ~0.095 lb
• OEM vs Generic: This is a factory-genuine Carrier OEM assembly, manufactured to exact rod-gap and ceramic insulation tolerances. Aftermarket igniters frequently ship with incorrect electrode gap spacing, leading to weak or inconsistent spark arcs that shorten the new igniter's service life and stress the control board's spark module.
• Install difficulty: 2/5 — Turn off power and gas supply before beginning. Tools needed: 1/4″ and 5/16″ nut drivers, needle-nose pliers. Photograph existing wiring connections before disconnecting the harness. Note: wire harness is sold separately (see part 50HJ440193 for wiring kit).
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. In-stock orders ship same business day from our warehouse.
