A furnace that will not ignite after the draft inducer runs typically has a failed igniter. The hot surface igniter should glow bright orange within 60 seconds. If it does not glow at all, it is cracked or burned out. If it glows weakly, it is degrading and should be replaced preventively. Average lifespan: 3 to 7 years.

Overview

The hot surface igniter (HSI) is the component that ignites the burners on your ICP RGS121HSAB0AAAA gas furnace. When the thermostat calls for heat, the furnace control board sends 120V to the igniter, which glows red-hot in 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) so you have everything needed for a clean, code-correct replacement. A failed igniter is one of the most common causes of no-heat calls — the element is brittle and degrades with every heating cycle until it finally cracks or fails to reach ignition temperature.

Installation Guide

Safety First — Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter. Shut off the gas supply.
Access — Remove the burner compartment service panel.
Document — Take a photo of the igniter mounting position and wiring before disconnecting.
Remove — Unplug the igniter wire harness, remove the mounting screw, and carefully withdraw the old igniter. Never touch the new element with bare fingers — skin oils cause hot spots and premature failure.
Install — Mount the new igniter so it sits correctly in the burner flame path, install the wiring kit, and reconnect per your photo.
Test — Restore gas and power, then run a heat cycle and confirm the igniter glows and the burners light within a few seconds.
