Overview
This is the OEM control board kit (part number 1183618) for the ICP/Tempstar/Heil RGS150LECA0AAAA furnace. The integrated furnace control board is the brain of the system: it manages the ignition sequence, sequences the inducer and blower motors, monitors safety limits and flame, and times every heat and cool cycle. When the board fails you may see no response to thermostat calls, blower or inducer problems, erratic cycling, or flashing diagnostic fault codes. This OEM kit restores correct timing and safety logic to the furnace.
