OEM Carrier Spark Electrode Ignitor (50HJ403022) for Model PY1RPA072074ACWA

This is the genuine OEM factory-specified spark electrode ignitor assembly for the Carrier PY1RPA072074ACWA packaged unit. The ignitor generates the high-voltage spark that ignites the gas burners at the start of every heat cycle. When it fails, the control board typically detects a no-ignition condition and enters a safety lockout — leaving you with cold air, a blinking fault code, and no heat. Replacing with the correct OEM assembly restores reliable ignition and clears lockout conditions immediately.

• Part Specs: OEM Part # 50HJ403022 | Spark electrode ignitor assembly | Supplied without wire harness | Factory-matched geometry and gap specification for precise arc placement at the burner port
• OEM vs Generic: This is a genuine Carrier OEM assembly — not an aftermarket approximation. Generic igniters often feature inconsistent electrode gaps and inferior ceramic insulators, leading to weak spark, misfires, and repeat lockouts. OEM ensures first-spark reliability and full control board compatibility.
• Install Difficulty: 3/5 — Shut off gas supply and disconnect power before servicing. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, multimeter (to verify high-voltage cable continuity). Note: wire harness and high-voltage cable (50HJ403024) are sold separately — inspect both before ordering only the assembly.
• Warranty & Shipping: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our warehouse when ordered before cutoff.
