Overview

This OEM hot surface igniter (HSI) is the direct-fire ignition source for the ICP / Tempstar / Heil RGS121LSAB0AAAA gas furnace. When the thermostat calls for heat, the integrated furnace control energizes this 120V silicon nitride element, which glows incandescent within seconds to light the main burners. A failed igniter is one of the most common causes of no-heat calls: the element grows brittle with every heating cycle and eventually cracks, leaving the furnace to lock out after several failed ignition attempts. This listing includes OEM igniter 1171306 and the matching igniter wiring kit 1188370 so the connector and harness pigtail are replaced together for a clean, reliable connection.

Installation Guide

Safety First — Disconnect power at the furnace switch and breaker; verify zero voltage with a multimeter and shut off the gas.
Access — Remove the furnace burner/service panel.
Document — Photograph the igniter bracket position and wire routing before disconnecting.
Remove — Unplug the igniter harness, remove the mounting screw, and lift out the old igniter without touching the element. Install the new wiring kit pigtail.
Install — Mount the new igniter so it sits centered in the burner flame path; never touch the white element with bare fingers. Reconnect per your photo.
Test — Restore gas and power, call for heat, and confirm the igniter glows and burners light within the ignition trial.
