Bryant LH33WP002A Furnace Ignition Control Circuit Board

OEM Carrier LH33WP002A ignition control circuit board is an OEM replacement module designed for Bryant, Payne, and Carrier gas furnaces. This circuit board acts as the furnace’s ignition control hub, coordinating spark generation and timing, gas valve operation, flame sensing, and safety lockout within a 24V control environment. It is intended as a direct replacement in systems that originally used LH33WP002A and is commonly listed under the alternate code 1068-12. Built to Carrier’s OEM specifications, the LH33WP002A preserves the same connector layout and electrical interfaces as the original board, enabling straightforward installation without harness modification. Typical applications include mid- to high-efficiency gas furnaces in the Bryant, Carrier, and Payne lines that rely on an integrated ignition module to ensure reliable start-up, flame verification, and safe operation. Replacing a failed ignition control board with this LH33WP002A can restore ignition sequence reliability and overall furnace performance by reestablishing proper spark timing, gas valve control, and flame sensing across the ignition cycle.
