Overview
This genuine OEM control board kit (factory part number 1183618, KIT CONTROL BOARD) is the integrated furnace control — the brain — of the ICP / Tempstar / Heil RGS150LTCB0AAAA. It sequences the entire heating cycle: it reads the thermostat call, runs the inducer and pressure-switch proving, energizes the hot surface igniter, opens the gas valve, monitors the flame sensor, and times the blower on and off. It also manages safety lockouts and flashes diagnostic fault codes. When the board fails, the furnace may be completely dead, stuck in lockout, blow cold air, or run the blower continuously. Supplied as a kit, it includes the mounting and connection hardware needed for a clean swap.
