The ignition control board serves as the central command module for the heating sequence — it orchestrates the inducer motor start, pressure switch verification, hot surface igniter activation, gas valve energization, and flame signal processing. When this board fails, the unit may enter a hard lockout, fail to initiate ignition, cycle off immediately after burner light-off, or display fault codes indicating a control board malfunction. Replacing it with the correct OEM part restores factory-engineered timing and safety logic.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 24V control voltage | 60 Hz | OEM part number LH33WP007 | Cross-reference: LH33WP007A | Weight: 0.84 lbs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM boards use factory-matched firmware and component tolerances.
