My furnace will not ignite. What part is bad?

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

This OEM hot surface igniter (part 1171306) with matching wiring kit (part 1188370) lights the burners in the ICP / Tempstar / Heil RGS121LDAB0AAAA gas furnace. On each heat call the control board sends voltage to the igniter, which glows red-hot to ignite the gas as it flows across the burners. Hot surface igniters are fragile and degrade with every cycle — the silicon nitride or carbide element thins, develops hairline cracks, and eventually fails open, leaving the furnace unable to light. Symptoms include no heat, a furnace that clicks but won't ignite, or a unit that locks out after several failed ignition attempts. The included wiring kit ensures a clean, factory-correct connection.
