Overview
This OEM control board is the electronic brain of your ICP / Tempstar / Heil RGS214HDGHAACAA gas furnace package unit. It manages the ignition sequence, blower timing, safety lockouts, and reheat operation, coordinating the igniter, gas valve, pressure switches, and blower motor on every call for heat. Sold here are the genuine circuit board reheat (part 1186501) and control board kit (part 1183618). When this board fails you will typically see no ignition, short cycling, the blower running continuously, or an LED fault/flash code that will not clear. Because the board governs every safety interlock, a failing board should be replaced with a genuine OEM unit rather than a generic substitute.
