The spark electrode ignitor initiates combustion by generating a high-voltage spark directly at the burner. When this component fails, the unit will attempt ignition, fail to light, and enter a safety lockout — leaving you with no heat and a system that won't restart without a manual reset. Replacing the ignitor with the correct OEM part restores reliable, code-compliant ignition performance.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 48GS400168 | Manufacturer Description: Spark Electrode Ignitor\/Electrode Assembly | Factory Authorized Carrier Part\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier component engineered to exact factory tolerances for the PY2PPB042090AA.
