This genuine OEM integrated furnace control board (part number 1176943, board number CEPL130438-01) is the brain of the ICP/Tempstar/Heil WFML110C066A1 gas furnace. It sequences the entire heat cycle: inducer startup, pressure switch proving, hot surface igniter warm-up, gas valve energizing, flame sensing, and blower on/off timing. It also runs onboard diagnostics and flashes fault codes through its LED. When the board fails, symptoms range from a furnace that won't respond to the thermostat at all, to short cycling, to a blower that runs continuously or never starts. Replacing the control board with the correct OEM part restores proper ignition sequencing and safety monitoring.
