Overview

This is a genuine OEM hot surface igniter (part number 1176919) with its mounting bracket (part number 1184324) for the ICP/Tempstar/Heil WFAR100C042A1 furnace. On each heat call the control board energizes the igniter; it glows white-hot to ignite the burner gas, then the flame sensor confirms ignition. Hot surface igniters are brittle and degrade over thousands of cycles, eventually cracking or failing to reach ignition temperature. A failed igniter is the most common reason a furnace clicks but produces no heat. This kit includes the matched bracket so the igniter seats at the correct position relative to the burner.
