OEM Carrier Spark Electrode Ignitor Assembly 50HJ403022 for Model PY1REA072074ACWA

This is the genuine OEM spark electrode ignitor assembly (part number 50HJ403022), factory-specified for the Carrier PY1REA072074ACWA packaged gas/electric unit. The ignitor assembly initiates combustion each heating cycle by generating a high-voltage spark at the burner. When this component degrades or fails, the control board will attempt ignition, detect no flame, and lock out the system — leaving you with a no-heat call and a flashing fault code. Replacing it with the correct OEM assembly restores reliable ignition from the very first cycle.

• Specs: 2-rod spark electrode design | Ceramic-body construction | Includes mounting bracket | Replaces legacy part 48VL400002 | Approx. 4.25″ L × 2.95″ W × 1.75″ H | ~0.095 lb
• OEM vs Generic: The OEM 50HJ403022 is manufactured to Carrier's exact electrode gap and ceramic insulation specifications. Generic igniters often ship with incorrect gap geometry or inferior ceramic, leading to misfires, premature cracking, and repeat service calls.
• Install difficulty: 2/5 — Turn off gas supply and 24V power before starting. Tools needed: 1/4″ nut driver, needle-nose pliers, and a flashlight. Photograph the original electrode orientation and wiring before removal. Reconnect the spark lead firmly to avoid arcing against the cabinet.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.
