ICP Control Board Kit for RGS101SFCA0AAA — Furnace Integrated Control | Ships Today

Overview

This is a genuine OEM control board kit (part number 1183618) for the ICP / Tempstar / Heil RGS101SFCA0AAA gas furnace. The integrated furnace control board is the brain of the heating system — it manages the ignition sequence, monitors the flame sensor and pressure switch, sequences the inducer and blower motors, and runs continuous safety diagnostics. When this board fails, the furnace may stop responding to thermostat calls entirely, lock out after a few ignition attempts, or flash diagnostic error codes through its onboard LED. Replacing it with the correct OEM kit restores reliable, code-compliant operation.
