ICP Control Board Kit for RGS102HTCA0AAA — OEM Furnace Control 1183618 | Ships Today

Overview

This is the genuine OEM integrated furnace control board kit (part #1183618) for the ICP / Tempstar / Heil RGS102HTCA0AAA gas furnace. The control board is the brain of the furnace, sequencing the igniter, gas valve, inducer motor, and blower while monitoring safety circuits and flame sense. When this board fails the furnace may fail to ignite, lock out, short-cycle, run the blower continuously, or flash diagnostic fault codes on the onboard LED. The kit ships with the board and mounting hardware needed for a direct replacement. Operating control voltage is 24V.
