ICP Furnace Control Board for RGS102HSCA0AAA — OEM 1183618 Kit | Ships Today

Overview

This OEM integrated furnace control board kit (part number 1183618) is the brain of the ICP / Tempstar / Heil RGS102HSCA0AAA gas furnace. It sequences the ignition cycle — inducer, igniter warm-up, gas valve, and blower timing — while monitoring the flame sensor, limit switches, and pressure switch for safe operation. The kit ships as a complete board assembly for a direct factory replacement. When this board fails, the furnace may short-cycle, fail to ignite, run the blower continuously, or go completely dead, since nearly every safety and timing function routes through it.

Specifications

Compatibility

Designed for the ICP-family RGS102HSCA0AAA gas furnace marketed under Tempstar, Heil, Comfortmaker and Day & Night. Verify the board number printed on your existing board before ordering, as ICP used several revisions across production runs.

Installation Guide

1. Safety First — Disconnect power at the furnace switch and breaker; verify zero voltage with a multimeter.
2. Access — Remove the blower-compartment service panel.
3. Document — Photograph every wire and connector on the old board before removing anything.
4. Remove — Unplug the harnesses, release the mounting standoffs, and lift out the failed board.
5. Install — Snap in the new board and reconnect each plug exactly per your photo.
6. Test — Restore power and run a full heat cycle, confirming proper inducer, ignition, and blower timing.

Signs You Need a Replacement

• Furnace is completely unresponsive on a heat call
• Short-cycling or random shutdowns mid-cycle
