OEM Carrier Spark Electrode Ignitor Assembly 50HJ403022 for Model PY1RPA036074ABWB

This is the genuine OEM spark electrode ignitor assembly (part number 50HJ403022), factory-specified for the Carrier PY1RPA036074ABWB gas-fired packaged unit. The ignitor assembly initiates combustion each time your system calls for heat — when it fails, the control board will attempt ignition, detect no flame, and lock out the system, leaving you with no heat and a fault code. Symptoms include a furnace that starts the ignition sequence but shuts down within seconds, repeated lockouts, or a visibly cracked/broken electrode.

• Specs: Spark electrode ignitor assembly | Includes ignitor element and mounting bracket | Ceramic body construction | Approx. 4.25″ L × 2.95″ W × 1.75″ H | ~0.095 lb | Replaces legacy part 48VL400002
• OEM vs Generic: This is a genuine Carrier-manufactured assembly, built to exact factory tolerances for electrode gap and ceramic insulation rating. Aftermarket igniters often use inferior ceramics that crack prematurely under thermal cycling, leading to repeat failures and callbacks.
• Install difficulty: 2/5 — Shut off gas and power before servicing. Tools needed: 1/4″ nut driver, flat-head screwdriver, work gloves. Never touch the ceramic electrode with bare hands — skin oils cause hot spots and premature cracking. Photograph wiring and electrode orientation before removal.
• Warranty: 1-year OEM factory warranty. In-stock orders ship same business day from our warehouse.
