ICP Furnace Control Board Kit for RGS091SECA0AAA — OEM Replacement | Ships Today

Overview

This OEM control board kit (part number 1183618) is the integrated furnace control that runs your ICP RGS091SECA0AAA system. It sequences the ignition, manages the inducer and blower, monitors the limit and pressure switches, and reads the flame signal — coordinating every safety and timing function. When the board fails you may see no response on a call for heat, blower or inducer faults, error codes flashing on the diagnostic LED, or a furnace that short-cycles. Replacing the board restores correct sequencing and the full suite of built-in safety logic.
