ICP Control Board for RGS214HFAA0AAAA — Furnace Control Kit | Ships Today

Overview

OEM 1183618 is the integrated furnace control board kit for the ICP/Heil/Tempstar RGS214HFAA0AAAA. This board is the brain of the furnace — it manages the ignition sequence, monitors safety switches (limits, pressure switch, flame sensor), times the inducer and blower, and supplies 24V to the thermostat circuit. When the board fails, the furnace may short-cycle, fail to ignite, leave the blower running continuously, or flash a diagnostic fault code on its onboard LED. The kit ships with the mounting hardware and connectors needed for a direct OEM replacement.

Installation Guide

1. Safety First — Disconnect furnace power and verify zero voltage with a multimeter.
2. Access — Remove the blower compartment / control panel cover.
3. Document — Photograph every harness and terminal on the old board before unplugging anything.
4. Remove — Disconnect all plugs and spade terminals, unscrew the board from its standoffs, and lift it out.
5. Install — Mount the new board, then transfer each connector exactly per your photo.
6. Test — Restore power, run a full heat cycle, and confirm correct ignition, blower timing, and no fault codes on the LED.

Signs You Need a Replacement
