The ignitor assembly generates the high-voltage spark that ignites the burner on each heating cycle. When this component fails, the furnace will attempt ignition, fail to light, and enter a safety lockout — leaving you with no heat. Common symptoms include a clicking sound with no flame establishment, repeated short cycling, or a steady lockout fault code on the control board.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 48GS400168 | 2-rod spark electrode ignitor assembly | Factory-matched OEM specification | Lightweight design at approximately 0.07 lbs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM ignitor assembly, ensuring exact electrode gap, ceramic insulator grade, and lead wire length.
