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 (HSI) is the ignition source for the ICP/Tempstar/Heil WFMR090B042B2 gas furnace. When the thermostat calls for heat, the control board sends voltage to the igniter, which glows to roughly 2,000°F and lights the burners. This kit includes the silicon-nitride igniter element (OEM 1176919) and its mounting bracket (OEM 1183455). A cracked, eroded, or open igniter is one of the most common no-heat failures: the furnace runs its pre-purge, fails to light, and locks out — often after several retry cycles. Replacing a worn igniter restores reliable single-attempt ignition and prevents repeated lockouts.
