The control board serves as the central command of your heating system — it sequences the inducer, hot surface igniter, gas valve, and flame sensor through every heating cycle. When the board fails, symptoms typically include a hard lockout with no ignition attempt, erratic cycling, fault codes on the board's diagnostic LED, or a complete loss of heating with the blower still running. Do not delay replacement: a failed control board can mask secondary faults and cause downstream component damage.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 24V | 60 Hz | Ignition Control Module | OEM part number LH33WP007 | Board weight approx. 0.84 lbs | Direct drop-in replacement with no field modification required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier board manufactured to exact factory tolerances.
