ICP Hot Surface Igniter Kit for RGS120LFCA0AAA — 120V Silicon Carbide | Ships Today

Overview

This OEM hot surface igniter kit (part 1171306, with wiring kit 1188370) is the ignition source for the ICP/Tempstar/Heil RGS120LFCA0AAA gas furnace. When the thermostat calls for heat, the furnace control board energizes this 120V silicon carbide igniter, which glows orange-hot and ignites the gas at the burners. The included wiring kit ensures a clean, OEM-spec connection to the control board. A failed igniter is the single most common cause of no-heat calls: the element becomes brittle with each heating cycle and eventually cracks, breaking the circuit so the burners never light.

Specifications

Compatibility

Engineered for the ICP family RGS120LFCA0AAA gas furnace and shared platform models sold under the Tempstar, Heil, Comfortmaker, and Day & Night brands. Always confirm your model and serial against the unit rating plate before ordering.

Installation Guide

1. Safety First — Switch off the furnace at the disconnect and breaker, then verify zero voltage with a multimeter.
2. Access — Remove the lower service/burner panel.
3. Document — Photograph the igniter bracket and wiring connector before disconnecting.
4. Remove — Unplug the igniter harness, remove the mounting screw, and lift the old igniter out by its ceramic base — never touch the element.
5. Install — Seat the new igniter so the element aligns with the burner ports, secure the screw, and connect the new wiring kit per your photo.
6. Test — Restore power, run a heat cycle, and confirm the igniter glows and the burners light within seconds.

Signs You Need a Replacement

• Furnace clicks and tries to start but never lights the burners
• Igniter shows visible cracks, blistering, or no orange glow
• Repeated short-cycling or lockout after a few ignition attempts
• Continuity/ohm test on the element reads open
