OEM Carrier Spark Electrode Igniter Assembly 50HJ403022 for Model PY1RPA036074ABWA

This is the genuine OEM spark electrode igniter assembly (part number 50HJ403022), the factory-specified replacement for the Carrier PY1RPA036074ABWA packaged gas unit. The igniter generates the high-voltage spark that lights the burner on each heating call. When it fails, the control board will attempt ignition, detect no flame, and lock out the system — leaving you with a unit that runs the inducer but produces no heat. This is one of the most common causes of a no-heat service call and one of the most straightforward repairs when using the correct OEM assembly.

• Specs: Spark electrode igniter assembly | Ceramic-body construction | Approx. 4.25″ L × 2.95″ W × 1.75″ H | Weight ~0.095 lb | Replaces legacy part 48VL400002 | Supplied without wire harness (order wire harness separately if needed)
• OEM vs Generic: This is a genuine Carrier OEM assembly manufactured to exact factory tolerances. Generic igniters may vary in electrode gap, ceramic grade, and bracket geometry — all of which affect spark reliability and service life. OEM is the only way to guarantee factory ignition performance and preserve any remaining equipment warranty.
• Install difficulty: 2/5 — Turn off gas supply and disconnect power at the breaker before beginning. Tools needed: 1/4" or 5/16" nut driver, needle-nose pliers. Photograph all wire connections before removal. Handle the ceramic electrode body carefully — oils from bare hands can cause premature cracking under heat.
• Warranty: 1-year OEM factory warranty against defects. In-stock orders ship same business day from our warehouse.

Compatibility: Engineered for the Carrier PY1RPA036074ABWA packaged rooftop/gas unit. This assembly also fits a broad range of Carrier, Bryant, and Payne models that share the same igniter platform — verify your unit's existing part number or data plate before ordering.
