It controls the igniter, opens the gas valve at the correct moment, verifies flame through the flame-sensing circuit, and locks out the system if ignition is not confirmed. This precise coordination protects your home from unburned gas while delivering dependable, on-demand heat.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms\u003c\/strong\u003e include a furnace that fails to ignite, repeated ignition lockouts, an igniter that glows but never lights the burners, delayed or rough ignition, short-cycling, or diagnostic error codes indicating a failed flame-sense or ignition fault. A defective board may also cause the furnace to attempt ignition several times before shutting down entirely.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e Ignition control is a safety-critical function, and the \u003cstrong\u003e63W26\u003c\/strong\u003e is engineered with the exact ignition timing, flame-sensing thresholds, and lockout logic specified for your Lennox equipment.
