ICP Furnace Control Board for WFSR080B048A1 — OEM Ignition Board | Ships Today

Overview

This OEM furnace control board is the brain of the ICP/Tempstar/Heil WFSR080B048A1 gas furnace. It sequences the entire heating cycle — energizing the inducer, proving pressure switches, firing the hot surface igniter, opening the gas valve, and timing blower on/off delays — while monitoring safety limits and flame sense. When the board fails, the furnace may not respond to the thermostat, lock out on a flashing fault code, run the blower continuously, or fail to ignite. Part number 1184783 is a direct OEM replacement that restores correct, safe sequencing.
