Overview
This OEM control board kit (part number 1183618) is the integrated furnace control (IFC) for the ICP/Tempstar/Heil RGS101LDCA0AAA. It is the brain of the furnace, sequencing the entire heat cycle: inducer start, pressure-switch proving, igniter warm-up, gas valve timing, flame sensing, and blower on/off delays, plus safety lockouts. When the board fails you may see no response on a heat call, blower or inducer that won't run, intermittent operation, or stored fault/error flash codes. Supplied as a kit for a direct OEM replacement that restores correct timing and safety logic.
