ICP Furnace Control Board for RGS101SECB0AAA — OEM Ignition Control Kit | Ships Today

Overview

This OEM control board kit (part 1183618) is the brain of your ICP Tempstar/Heil RGS101SECB0AAA gas furnace. It manages the entire heating sequence — monitoring the thermostat call, sequencing the inducer, igniter, gas valve, and blower, and reading the flame sensor and limit switches for safe operation. A failed board is a frequent cause of a no-heat condition. The kit includes the integrated furnace control with the diagnostic LED used to read fault codes during troubleshooting. Replacing the board restores proper ignition timing, blower delays, and safety lockout behavior.
