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 is the genuine OEM hot surface ignition kit for the ICP / Tempstar / Heil RGS121SRCB0AAA gas furnace, including the hot surface igniter (part number 1171306) and the matching igniter wiring kit/harness (part number 1188370). The hot surface igniter glows red-hot on a call for heat to ignite the burner gas; it is one of the most common furnace failure points because the element is brittle and degrades with every heating cycle. The included wiring kit ensures a clean, correct electrical connection and replaces brittle or heat-damaged leads. When the igniter cracks or the element opens, the furnace will not light — you may hear the gas valve and inducer cycle with no ignition, or see a lockout fault. This complete kit restores reliable ignition with the exact OEM components.
