ICP Furnace Control Board for RGS102SFCB0AAA — OEM 1183618 Kit | Ships Today

Overview

This OEM integrated furnace control board kit (part #1183618) is the brain of the ICP/Tempstar/Heil RGS102SFCB0AAA gas furnace. It sequences ignition, monitors flame and pressure safeties, controls the inducer and blower motors, and runs the diagnostic LED fault codes. A failed board causes intermittent operation, no ignition, blower problems, or a completely dead furnace. The board operates on a 24V control circuit and switches line-voltage loads through its onboard relays. Replacing the board restores reliable, code-compliant operation of the entire heating sequence.
