ICP Hot Surface Igniter Kit for RGS091LTBA0AAAA — With Wiring | Ships Today

Overview

This OEM hot surface igniter kit for ICP/Tempstar/Heil gas furnace model RGS091LTBA0AAAA includes the igniter (OEM part 1171306) and the matching igniter wiring kit (OEM part 1188370) for a complete, ready-to-install replacement. A hot surface igniter (HSI) is the element that glows red-hot when the furnace control board energizes it, igniting the gas at the burners on each heat call. Igniters are a wear item — the element becomes brittle and eventually cracks from repeated heating and cooling cycles. The included wiring kit ensures a clean electrical connection and is the recommended companion to any igniter replacement, since brittle or heat-damaged igniter leads are a frequent cause of repeat no-heat failures. Replacing the HSI restores reliable ignition and eliminates the long, frustrating no-heat lockouts caused by a failed igniter.

Specifications

Compatibility

Designed for ICP-family gas furnaces (Tempstar, Heil, Comfortmaker, Arcoaire) and a direct fit for model RGS091LTBA0AAAA. Confirm your furnace uses igniter part 1171306 (or a listed supersession). The included wiring kit 1188370 adapts the new igniter to the existing furnace harness.

Installation Guide

1. Safety First — Shut off gas and electrical power to the furnace. Verify zero voltage with a multimeter before working near the burner assembly.
2. Access — Remove the furnace burner / blower access panel to reach the igniter at the burner manifold.
3. Document — Photograph the igniter mounting position and wiring connection before removal.
4. Remove — Unplug the igniter lead, remove the mounting screw(s), and carefully withdraw the old igniter — never touch the ceramic element with bare fingers.
5. Install — Mount the new 1171306 igniter in the exact original position, then connect the 1188370 wiring kit, handling the element only by its ceramic base.
6. Test — Restore gas and power, start a heat cycle, and confirm the igniter glows bright and the burners light promptly and evenly.

Signs You Need a Replacement

• Furnace blower runs but burners never light (no-heat)
• Igniter no longer glows or glows weak/uneven
• Visible cracks or breaks in the ceramic element
• Repeated ignition lockouts or short cycling on heat calls
