ICP Hot Surface Igniter for WFSR100C042A2 — OEM 1176919 with Bracket | Ships Today

Overview

This OEM hot surface igniter kit is the factory replacement ignition component for the ICP Tempstar/Heil WFSR100C042A2 gas furnace. It includes the igniter element (OEM part 1176919) and its mounting bracket (OEM part 1184324). When the thermostat calls for heat, the control board energizes this igniter; it glows to roughly 2,000°F to ignite the gas at the burners. A cracked element or a failed glow is the single most common cause of furnace no-heat calls — if the igniter does not glow, the gas valve will not open and the furnace locks out. Replacing it with the correct OEM part restores reliable ignition and avoids repeated lockout cycles.

Installation Guide

1. Safety First — Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter.
2. Access — Remove the furnace burner/service panel.
3. Document — Photograph the igniter wiring and bracket orientation before disconnecting.
4. Remove — Unplug the igniter connector, remove the bracket screw(s), and carefully withdraw the old igniter without touching the new element with bare fingers.
5. Install — Mount the new igniter and bracket, position the element over the burner per the photo, and reconnect the harness.
6. Test — Restore power, start a heat cycle, and confirm the igniter glows and the burners light.
