Overview

The hot surface igniter (HSI) ignites the burners on your ICP RGS121HSAA0AAAA gas furnace. When the thermostat calls for heat, the control board sends 120V to the igniter, which glows red-hot within seconds to light the gas at the burner. This OEM kit includes the silicon carbide igniter (OEM part 1171306) and the matching igniter wiring kit (OEM part 1188370) for a complete, code-correct replacement. The igniter element is brittle and degrades with every heating cycle until it finally cracks or can no longer reach ignition temperature — making it one of the most common causes of a no-heat furnace.

Installation Guide

Safety First — Disconnect power at the furnace switch and breaker, verify zero voltage with a multimeter, and shut off the gas supply.
Access — Remove the burner compartment service panel.
Document — Photo the igniter mounting position and wiring before disconnecting.
Remove — Unplug the igniter harness, remove the mounting screw, and withdraw the old igniter. Never touch the new element with bare fingers — skin oils create hot spots that shorten its life.
Install — Mount the new igniter in the correct burner flame path, install the wiring kit, and reconnect per your photo.
Test — Restore gas and power, run a heat cycle, and confirm the igniter glows and the burners light within a few seconds.
