Overview
This OEM hot surface igniter assembly is the direct-fit ignition component for the ICP / Heil / Tempstar RGS121HTAB0AAAA gas furnace. The kit includes OEM ignitor part number 1171306 plus the matching igniter wiring kit 1188370, so you replace the element and its harness together for a clean, reliable repair. The hot surface igniter glows red-hot on each call for heat to ignite gas at the burners. Its brittle ceramic element is among the most common furnace failure points — thermal cycling, soot accumulation, and rough handling cause hairline cracks that break the heating cycle. Common symptoms include the blower running with no heat, repeated ignition attempts ending in lockout, an igniter that never glows, or short-cycling on a hard restart.

Compatibility
Engineered as a direct OEM replacement for the ICP / Heil / Tempstar / Comfortmaker RGS121HTAB0AAAA furnace. The included wiring kit allows a plug-and-play connection without splicing the existing harness. Always confirm your model and serial tag before ordering.
Installation Guide
- Safety First — Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter.
- Access — Remove the lower service panel to expose the burner assembly.
- Document — Photograph the igniter bracket position and wiring routing before disconnecting.
- Remove — Unplug the igniter connector, remove the mounting screw, and lift the old igniter clear — handle only by the ceramic base, never the element.
- Install — Mount the new igniter at the same depth and angle, secure the screw, and connect the new wiring kit per your photo.
- Test — Restore power, initiate a heat call, and confirm the igniter glows and the burners light within seconds.
Signs You Need a Replacement
- Igniter no longer glows on a call for heat.
- Furnace locks out after repeated failed ignition attempts.
- Visible cracks, blistering, or white spots on the element.
- Blower runs but the system delivers no warm air.
