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 (part numbers 1186861 and 1177663) is the ignition source for the gas heating section of your ICP WPG4604090RKA1 package unit. On a call for heat, the control energizes the igniter, which glows red-hot to light the burners. Hot surface igniters are fragile and degrade with every heating cycle — the silicon carbide or nitride element develops microcracks, draws weaker current, and eventually fails to reach ignition temperature. A bad igniter is the leading cause of no-heat furnace lockouts. Replacing it restores dependable ignition and prevents repeated failed-light retries.
