Overview
This is the OEM control board kit (part number 1183618) for the ICP / Tempstar / Heil RGS213LECA0AAAA gas furnace. The integrated furnace control board manages the entire ignition sequence — it powers the inducer, energizes the hot surface igniter, opens the gas valve, monitors the flame sensor and pressure switches, and runs the safety lockouts and blower timing. When this board fails, the furnace usually will not start, locks out after a few attempts, short-cycles, or runs the blower continuously. Because it governs every step of start-up and safety, a faulty board is one of the most common no-heat failures. This genuine OEM kit is a direct, plug-in replacement with the correct firmware and connector layout.
