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 (HSI) lights the burners on your ICP/Heil/Tempstar RGS121LTBA0AAAA gas furnace. When the thermostat calls for heat, the control board powers the igniter, which glows white-hot to ignite the burner gas. A cracked, chipped, or burned-out igniter will leave the furnace cycling the inducer and gas valve with no flame, usually ending in an ignition-failure lockout and no heat. This kit pairs OEM igniter 1171306 with igniter wiring kit 1188370 for a complete replacement.
