Overview
This OEM integrated furnace control board (ICP part number 1187101) is the electronic controller for your ICP/Tempstar/Heil WFEL045A036A1 gas furnace. It sequences ignition, controls the blower and inducer, monitors flame sensing, and enforces safety lockouts. A failed board can leave the furnace unable to ignite, short-cycling, running the blower nonstop, or flashing diagnostic fault codes. This exact OEM 1187101 board restores correct, safe operation without universal-board guesswork.
