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 (part #1179966) is the ignition component for the ICP/Tempstar/Heil RGS303LEAA0AAAA gas furnace. When the furnace calls for heat, the control board energizes this igniter, which glows red-hot to light the burner gas. The silicon nitride element is brittle and degrades with each heating cycle, eventually cracking and failing. Common symptoms include the blower running with no heat, the igniter never glowing, a furnace that locks out after several ignition attempts, or burners that won't light. This direct-fit OEM igniter restores dependable ignition.
