Overview
This OEM control board kit (part number 1183618) is the electronic brain of the ICP/Tempstar/Heil RGS240LEFA0AAAA furnace. It manages the entire heating sequence — inducer start, pressure switch proving, igniter warm-up, gas valve timing, blower on/off delays, and safety lockouts — while monitoring the limit and flame-sensing circuits. Control boards fail from voltage surges, relay wear, cracked solder joints, and burnt connectors. Symptoms of a failing board include the furnace not responding to a call for heat, the blower or inducer running continuously, erratic or out-of-sequence operation, and diagnostic LED fault codes that point to a board fault.
