Overview

This OEM hot surface igniter lights the burners on the gas-heat section of your ICP package unit. On a call for heat, the igniter control board (PN 1186861) sends voltage to the igniter (PN 1177663), which glows red-hot to ignite the gas as the valve opens. Hot surface igniters are brittle and wear out with every heating cycle — the silicon-carbide or nitride element develops hairline cracks, oxidizes, and eventually fails to reach ignition temperature. The classic symptom is a furnace that goes through its pre-purge but never lights, or one that locks out after several failed ignition attempts. Replacing the igniter and its control board together restores reliable, on-demand ignition.
