Overview

This OEM hot surface igniter (ignitor part number 1177663, with related igniter control board 1186861) is the factory ignition component for the ICP / Tempstar / Heil WPG4484115RKB1 unit. On a heating call, the igniter element electrically heats to a glowing temperature to light the burner gas. Hot surface igniters are brittle and degrade with every cycle, eventually cracking or failing to reach ignition temperature — the leading cause of no-heat calls. This genuine OEM replacement restores fast, dependable ignition and reliable furnace operation.
