ICP Hot Surface Igniter Kit for RGS121LFBA0AAAA — OEM 1171306 | Ships Today

Overview

This OEM hot surface igniter kit for the ICP RGS121LFBA0AAAA gas furnace includes the igniter (part number 1171306) and the matching igniter wiring kit (part number 1188370). On each heat call, the control board energizes the igniter; it glows white-hot to ignite the gas at the burners. Hot surface igniters are brittle and degrade with every cycle — they crack, develop hairline fractures, or lose the ability to reach ignition temperature. The result is no-heat calls, repeated ignition lockouts, or delayed ignition with a rollout risk. The included wiring kit ensures a clean, corrosion-free electrical connection to the new igniter.

Specifications

Compatibility

Designed for the ICP RGS121LFBA0AAAA gas furnace and shared-platform Tempstar, Heil, and Comfortmaker furnaces using the same ignition system. Confirm part numbers 1171306 and 1188370 against your unit's parts list before ordering.

Installation Guide

1. Safety First — Shut off gas and disconnect power. Verify zero voltage with a multimeter.
2. Access — Remove the furnace burner compartment service panel.
3. Document — Photograph the igniter position, bracket, and wiring routing before disconnecting.
4. Remove — Unplug the igniter harness, remove the mounting screw, and carefully lift out the old igniter without touching the element.
5. Install — Mount the new igniter (handle only by its ceramic base), install the new wiring kit, and route the harness clear of hot surfaces.
6. Test — Restore gas and power, run a heat cycle, and confirm the igniter glows and lights the burners promptly.

Signs You Need a Replacement

• No heat with the blower running but burners never light
• Visible cracks or breaks in the igniter element
