The ignition control board is the central command module for the heating sequence — it manages the inducer motor, hot surface igniter, gas valve, and flame sensor circuit in precise timed stages. When this board fails, the unit may enter a hard lockout, attempt ignition with no result, fail to prove flame, or display fault codes indicating a failed ignition sequence. Replacing it with the correct OEM board restores factory-programmed timing and safety logic.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 24V AC control voltage | 60 Hz | OEM Part # LH33WP007 | Compatible board reference: 1068-15 | Weight: 0.84 lbs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM board carries exact factory-programmed ignition timing, lockout thresholds, and safety delays.
