OEM Carrier Spark Electrode Igniter (50HJ403022) for Model PY1REA048115AAWB

This is the factory OEM spark electrode igniter assembly for the Carrier PY1REA048115AAWB packaged gas/electric unit. The igniter is the first active component in the heat sequence — when the control board calls for heat, it energizes the igniter to produce the high-voltage spark that lights the burners. A failed or cracked igniter causes the system to enter ignition lockout, leaving you with a unit that attempts to start, fails repeatedly, and ultimately shuts down on safety lockout. Symptoms include no heat, repeated clicking with no flame, or a blinking fault code on the control board indicating ignition failure.

• OEM Part Number: 50HJ403022 | Carrier-factory-specified spark electrode igniter assembly — no wire harness included (sold separately)
• OEM vs Generic: This is a genuine Carrier OEM assembly with factory-matched electrode gap, ceramic insulator rating, and bracket geometry. Aftermarket igniters frequently suffer from improper spark gap tolerance, leading to weak ignition or premature ceramic cracking — use OEM for reliable, long-term performance.
• Install Difficulty: 2/5 — Shut off gas and power before servicing. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Photograph existing wiring and electrode position before removal. Avoid touching the ceramic tip — skin oils accelerate cracking under heat cycling.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
