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 assembly fits the gas-heat section of the ICP/Tempstar/Heil WPG4604115RKB1 packaged gas/electric unit. It covers the factory ignitor (part number 1177663) and the matching control board igniter (part number 1186861). On a call for heat, the control board energizes the igniter, which glows incandescent and lights the main burners. Hot surface igniters are brittle and degrade with every heating cycle — hairline cracks, contamination, and resistance drift eventually cause no-light or short-cycling no-heat conditions. A fresh OEM igniter restores fast, reliable ignition.
