The ignition control board is the brain of your system's heating sequence — it manages the inducer motor, hot surface igniter, gas valve, and flame sensor in precise coordination. When this board fails, symptoms typically include a complete no-heat condition, repeated ignition lockout fault codes, erratic cycling, or failure to prove flame even when the igniter and sensor test good individually. Replacing the board with a genuine OEM unit restores factory-programmed timing and safety thresholds.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 24V | 60 Hz | OEM Part Number LH33WP007 | Ignition control \/ IFC board | Replaces LH33WP007A variant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM boards are programmed with Carrier's exact ignition timing, lockout retry logic, and fault code sequences.
