Overview
This is the genuine OEM hot surface igniter (part 1171306) with its matching wiring kit (part 1188370) for the ICP / Heil / Tempstar RGS121HFAB0AAAA gas furnace. The igniter is a silicon-carbide or silicon-nitride element that glows red-hot when energized to light the burners at the start of each heat cycle. Because it is heated to over 2,000°F on every call, it is a wear item that eventually cracks or develops hairline fractures, leaving the furnace unable to ignite. The included wiring kit replaces the brittle, heat-aged igniter harness and connector so you restore a reliable, clean connection along with the new element.

Installation Guide
- Safety First — Turn off gas and disconnect electrical power. Verify zero voltage with a multimeter.
- Access — Remove the furnace burner-compartment access panel.
- Document — Photograph the igniter position, bracket, and harness routing before removal.
- Remove — Unplug the igniter harness and remove the mounting screw. Handle the old igniter by the ceramic base only — never touch the element.
- Install — Mount the new igniter without touching the element, install the new wiring kit, and route the harness away from hot surfaces.
- Test — Restore gas and power, start a heat call, and confirm the igniter glows and the burners light within the normal trial-for-ignition period.
Signs You Need a Replacement
- Furnace blower runs but burners never light (no ignition)
- Visible crack, blistering, or white spots on the igniter element
- Igniter glows weakly, intermittently, or not at all
- Repeated lockouts after several failed ignition attempts
