ICP Control Board Kit for RGS210LTAA0AAAA — OEM Replacement | Ships Today

Overview

This is a genuine OEM control board kit (part number 1183618) for the ICP/Tempstar/Heil RGS210LTAA0AAAA. The control board is the brain of the unit — it sequences ignition, manages the blower and inducer, monitors safety switches, runs the diagnostic LED, and coordinates the thermostat call with the gas valve and igniter. The kit includes the replacement board and mounting hardware needed for a direct swap. Control boards fail from power surges, heat stress, corrosion, and aging components, often showing up as intermittent operation, blower or inducer faults, or a unit that simply will not respond. Replacing the board with the correct OEM kit restores full, reliable sequencing and on-board diagnostics.
