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 electrode lights the burners on your ICP Tempstar Heil RGS243HRAA0AAAA gas furnace. On each call for heat the control board energizes the igniter, which glows red-hot and ignites the gas as the valve opens. Igniters are brittle and degrade with every heating cycle — cracks, erosion, or a break leave the furnace with a working blower and gas valve but no flame, often producing a furnace that ignites intermittently or locks out after several failed tries. This direct-fit electrode restores dependable ignition.
