ICP Hot Surface Igniter Kit for RGS121LEBA0AAAA — OEM with Wiring Harness | Ships Today

Overview

This OEM hot surface igniter kit for the ICP/Tempstar/Heil RGS121LEBA0AAAA includes the genuine igniter (part 1171306) and the matching igniter wiring kit (part 1188370). On each call for heat, the control board energizes the igniter, which glows red-hot to light the burner gas. Hot surface igniters are fragile and wear out — they crack, develop hairline fractures, or simply burn out after thousands of cycles. The most common furnace no-heat complaint is an igniter that no longer glows or that glows but won't ignite the burners. The included wiring kit ensures a clean, corrosion-free connection so the new igniter performs reliably.

Specifications

Compatibility

Built for the ICP/Tempstar/Heil RGS121LEBA0AAAA gas furnace and related Carrier-built ICP models using this hot surface igniter and connector. Match the igniter mounting bracket and connector style to your existing part before installing.

Installation Guide

1. Safety First — Disconnect electrical power and shut off the gas; verify zero voltage with a multimeter.
2. Access — Remove the burner compartment door.
3. Document — Photograph the igniter position and wiring routing before disconnecting.
4. Remove — Unplug the igniter connector, remove the mounting screw, and lift out the old igniter — handle only by the ceramic base, never the element.
5. Install — Mount the new igniter without touching the silicon-carbide element, then connect the new wiring kit per your photo.
6. Test — Restore gas and power, start a heat cycle, and confirm the igniter glows and lights the burners smoothly.

Signs You Need a Replacement

• Furnace blower runs but produces no heat
• Igniter does not glow on a heat call
• Igniter glows but burners fail to light
