OEM Carrier Spark Electrode Ignitor Assembly (50HJ403022) for Model PY1RPA150224ADWB

This is the genuine OEM Carrier spark electrode ignitor assembly, part number 50HJ403022, factory-specified for the Carrier PY1RPA150224ADWB packaged gas unit. The ignitor assembly is the first critical component in every heating cycle — it generates the high-voltage spark that lights the burner. When this part fails, the control board will attempt ignition one to three times before entering a hard lockout, leaving you with no heat and a flashing fault code. Common failure symptoms include a furnace that clicks repeatedly but never fires, a system that goes into lockout shortly after a call for heat, or visible cracking and carbon tracking on the ceramic ignitor body.

• Part Number: 50HJ403022 | Replaces legacy part 48VL400002 | Sold without wire harness — reuse your existing harness
• OEM vs Generic: This is a genuine Carrier OEM assembly manufactured to factory spark-gap and ceramic tolerances. Aftermarket igniters frequently ship with incorrect electrode spacing, causing unreliable sparking, premature ceramic cracking, and shortened service life — especially in high-cycle commercial applications.
• Install Difficulty: 3/5 — Gas appliance work requires caution. Shut off gas supply and 24V control power before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, and a digital multimeter to verify the spark circuit. Photograph all wiring connections before disconnecting. Do not touch the ceramic electrode with bare hands — skin oils accelerate thermal degradation.
• Warranty: 1-year OEM Carrier factory warranty. In-stock orders ship same business day from our warehouse.

Compatibility: Factory-matched for the Carrier PY1RPA150224ADWB packaged unit. Also fits a broad range of Carrier, Bryant, and Payne gas-fired systems that specify part 50HJ403022. Always verify the part number on your existing ignitor or equipment data plate before ordering. Our fitment team is available to confirm compatibility before you purchase — no guesswork required.
