ICP Hot Surface Igniter for RGS101LDAA0AAAA — 120V Silicon Nitride HSI with Wiring Kit | Ships Today

Overview

This OEM hot surface igniter (HSI), part number 1171306, is the ignition component for the ICP/Tempstar/Heil RGS101LDAA0AAAA gas furnace. On a heat call, the integrated furnace control energizes the igniter, which heats to roughly 2,000°F and lights the gas at the burners. The listing includes the matching igniter wiring kit (1188370) for a clean tie-in to the existing harness. The HSI is among the most common no-heat failure points: repeated thermal cycling makes the silicon element brittle until it cracks and opens the circuit. Typical symptoms include the inducer running with no burner ignition, repeated ignition lockouts, or a visibly cracked element.

Specifications

Compatibility

Designed for the ICP/Tempstar/Heil/Comfortmaker RGS101LDAA0AAAA gas furnace and shared across many RGS-series models using the same igniter platform. Confirm against your unit's parts breakdown before ordering.

Installation Guide

1. Safety First — Disconnect power at the furnace switch, verify zero voltage with a multimeter, and shut off the gas supply.
2. Access — Remove the burner compartment service panel.
3. Document — Photograph the igniter bracket and wiring before disconnecting.
4. Remove — Unplug the igniter harness, remove the mounting screw, and lift out the old igniter without touching the element.
5. Install — Mount the new igniter, route and connect the included wiring kit per your photo, and verify alignment over the burner.
6. Test — Restore gas and power, initiate a heat call, and confirm the igniter glows and the burners light reliably.

Signs You Need a Replacement

• Inducer runs but burners never ignite
• Furnace locks out after repeated ignition attempts
• Visible crack or break in the silicon element
• No glow when a heat call is initiated
