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) and matching igniter wiring kit (part #1188370) are the factory-specified ignition components for the ICP / Heil / Tempstar RGS121LRAA0AAAA gas furnace. The igniter is a 120V hot surface element that glows red-hot to light the main burners on each heat call. As the silicon nitride element ages through thousands of heating cycles, it can crack, develop hairline fractures, or lose conductivity, causing the furnace to lock out and fail to fire. Typical symptoms include the inducer and blower running with no ignition, repeated lockouts after three failed tries, or a visibly broken or whitened element. The included wiring kit restores a clean, corrosion-free connection to the furnace control board.
