ICP Control Board Kit for RGS214SEAA0AAAA — Furnace Control | Ships Today

Overview

This OEM control board kit (part number 1183618) is the brain of your ICP, Tempstar, or Heil gas furnace. The integrated furnace control manages the entire heating sequence — it sequences the inducer, igniter, gas valve, and blower, monitors the flame and safety circuits, and runs self-diagnostics with flashing fault codes. When a board fails, the symptoms range widely: no heat, no blower, erratic short-cycling, or a unit that won't respond to the thermostat at all. Common failure causes include power surges, burnt relays, and corroded or scorched traces. This complete kit includes the board and required hardware for a clean OEM replacement.

Specifications

Compatibility

Built for the ICP / Tempstar / Heil model RGS214SEAA0AAAA and other furnaces that originally used OEM part 1183618. Confirm the board's connector layout and mounting footprint against your existing control before installing.

Installation Guide

1. Safety First — Disconnect power at the furnace switch and breaker and verify zero voltage with a multimeter.
2. Access — Remove the blower-compartment service panel.
3. Document — Photograph every connector and wire on the old board before disconnecting anything.
4. Remove — Unplug all harnesses, remove the mounting screws, and lift out the old board.
5. Install — Mount the new board from the kit and reconnect each harness exactly per your photo.
6. Test — Restore power, call for heat, and verify a full ignition-to-blower cycle with no fault codes.

Signs You Need a Replacement
