ICP Hot Surface Igniter for RGS091SFAA0AAAA — Furnace Ignition Kit | Ships Today

Overview

This OEM hot surface igniter (part #1171306) is the ignition component for the ICP/Heil/Tempstar RGS091SFAA0AAAA gas furnace, and it ships with the matching igniter wiring kit (part #1188370). On a call for heat, the furnace control board energizes the igniter, which heats to roughly 1,800–2,500°F to light the burners. A cracked element, carbon buildup, or a broken wiring harness is one of the most common causes of no-heat failures. Because the silicon-carbide or silicon-nitride element is fragile, replacing the igniter along with a fresh wiring kit restores reliable ignition and prevents repeat failures from a brittle, corroded harness.

Specifications

Compatibility

Designed as a direct OEM replacement for the ICP/Heil/Tempstar RGS091SFAA0AAAA furnace. The same igniter and wiring kit are shared across many ICP-family RGS-series gas furnaces. Always confirm your model and serial number before ordering.

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 mounting and wire harness routing before disconnecting.
4. Remove — Unplug the igniter harness, remove the mounting screw, and lift out the old igniter. Handle only by the ceramic base — never touch the element.
5. Install — Mount the new igniter, install the new wiring kit, and reconnect per your photo.
6. Test — Restore power, call for heat, and confirm the igniter glows and burners light reliably.

Signs You Need a Replacement

• Furnace blower runs but burners never ignite (no heat).
• Igniter shows visible cracks, blisters, or no longer glows.
• Repeated lockouts after several failed ignition attempts.
• Brittle or frayed igniter wiring harness.
