ICP Hot Surface Igniter & Wiring Kit for RGS120SRAA0AAA — OEM Ignitor | Ships Today

Overview

This genuine OEM hot surface igniter (part 1171306) with its matching wiring kit (part 1188370) ignites the burners on the ICP Tempstar Heil RGS120SRAA0AAA gas furnace. On a heat call, the control board energizes the igniter, which glows white-hot to light the gas at the burners. Hot surface igniters are brittle and degrade with every cycle — the element develops hairline cracks and eventually fails open. The included wiring kit ensures a clean, correct electrical connection and replaces brittle or heat-damaged leads. Typical failure symptoms include no ignition, the furnace locking out after several failed trials, a glowing igniter that never lights the burners, or a visibly cracked element.

Compatibility

Designed for the ICP Tempstar Heil RGS120SRAA0AAA gas furnace and ICP-family models using the same hot surface igniter and connector. Confirm the igniter style and mounting against your existing part.

Installation Guide

1. Safety First — Disconnect power at the furnace switch and breaker; verify zero voltage with a multimeter.
2. Access — Remove the furnace burner/service panel.
3. Document — Photograph the igniter position and wiring routing before disconnecting.
4. Remove — Unplug the igniter connector and unfasten the mounting screw; handle the old igniter by its ceramic base only.
5. Install — Mount the new igniter without touching the element, then connect the new wiring kit per your photo.
6. Test — Restore power, start a heat cycle, and confirm the igniter glows and lights the burners.
