OEM Carrier Spark Electrode Igniter Assembly (50HJ403022) for Model PY1REA036074ABWA

This is the genuine OEM Carrier spark electrode igniter assembly (part number 50HJ403022), the factory-specified replacement for the Carrier PY1REA036074ABWA packaged gas unit. The igniter initiates combustion at the burner on every heat call — when it fails, the control board attempts ignition, detects no flame, and locks out the system, leaving you with a no-heat call and a blinking fault code. Replacing the igniter assembly is one of the most common furnace repairs and restores reliable startup immediately.

• 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
• OEM vs Generic: This is a genuine Carrier OEM assembly — factory-matched electrode gap and ceramic grade. Generic igniters can have inconsistent spark timing and thinner ceramic bodies, leading to premature cracking under thermal cycling.
• Install difficulty: 2/5 — Shut off gas and 24V power before starting. Tools needed: 1/4″ nut driver, needle-nose pliers. Do not touch the ceramic igniter element with bare hands — skin oils accelerate cracking. Photograph wire routing before disconnecting.
• Warranty: 1-year OEM factory warranty. In-stock orders ship same business day from our warehouse.
