This high-tension cable carries the ignition signal from the boiler's control board to the igniter\/electrode, delivering the spark or high-voltage charge needed to light the burner reliably at the start of every heating cycle. A sound igniter cable is essential for consistent, on-demand ignition and safe combustion.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms\u003c\/strong\u003e include ignition lockout or fault codes, the boiler failing to fire, delayed or intermittent ignition, repeated ignition attempts before the burner lights, and no heat or hot water. Heat cycling, moisture, and vibration can crack the cable insulation or corrode the connectors, weakening the spark or breaking the circuit entirely.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e The Y5374 is built to the exact length, connector style, and high-voltage insulation rating of your Lennox condensing boiler's ignition system.
