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 (factory part 1171306), supplied with its matching wiring kit (1188370), ignites the burners on the ICP/Tempstar/Heil RGS121LDAA0AAAA gas furnace. On a call for heat, the control board energizes the igniter, which glows to roughly 1,800–2,500°F and lights the gas as it flows across the burners. Igniters are brittle silicon-carbide or silicon-nitride elements that crack from age, thermal cycling, vibration, or handling. A failed igniter is one of the most common no-heat causes: the inducer and gas valve sequence normally but the burners never light, often ending in ignition lockout. The included wiring kit ensures a clean, correctly terminated connection to the harness.
