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 number 1171306) ships with its matching wiring/connector kit (part number 1188370) for the ICP / Tempstar / Heil RGS121SFCA0AAA gas furnace. The hot surface igniter (HSI) glows red-hot when the control board calls for heat, igniting the gas at the burners. It is a wear item — the silicon-carbide or silicon-nitride element becomes brittle and eventually cracks from repeated thermal cycling. The included wiring kit replaces the original pigtail/connector so you get a clean, reliable electrical connection rather than reusing a heat-fatigued harness. A failed igniter is the single most common cause of no-heat calls on modern furnaces.

Access — Remove the furnace burner-compartment service panel.
Document — Photograph the igniter position, bracket, and wiring routing before disconnecting.

Test — Restore gas and power, call for heat, and confirm the igniter glows and the burners light promptly.
