ICP Furnace Control Board Kit for RGS210LRAA0AAAA — OEM Ignition Control | Ships Today

Overview

This OEM control board kit (part #1183618) is the brain of the ICP/Heil/Tempstar RGS210LRAA0AAAA gas furnace. It sequences the entire heat cycle — reading the thermostat call, proving the inducer and pressure switch, energizing the igniter, opening the gas valve, monitoring flame, and timing the blower on and off delays. When the board fails, the furnace may go dead, lock out, short-cycle, or run the blower continuously. This factory kit includes the board matched to the furnace's wiring harness and software so ignition and safety timing behave exactly as designed. Replacing a degraded board restores reliable, code-correct furnace operation.

Installation Guide

1. Safety First — Disconnect electrical power to the furnace and verify zero voltage with a multimeter.
2. Access — Remove the blower-compartment service panel to expose the control board.
3. Document — Photograph every wire connection and label terminals before disconnecting.
4. Remove — Unplug the harnesses, release the board standoffs/screws, and lift out the old control.
5. Install — Mount the new board, reconnect each harness per your photo, and set any DIP switches to match the original.
6. Test — Restore power, run a full heat cycle, and confirm proper ignition and blower timing.
