ICP Hot Surface Igniter for RGS120LEAA0AAA — 120V Silicon Carbide Ignitor with Wiring Kit | Ships Today

Overview

This OEM hot surface igniter (OEM #1171306) is the ignition source for the ICP / Tempstar / Heil RGS120LEAA0AAA gas furnace. On a call for heat the control board energizes the igniter, which heats to roughly 2,000°F to light the burners. This part ships with the matching OEM wiring kit (OEM #1188370) so you get the correct harness and connector for a clean, code-correct replacement. A failed igniter is one of the most common causes of no-heat calls: the most frequent failure mode is a cracked silicon carbide element, which reads open on a multimeter and leaves the burners cold even though the rest of the sequence runs normally.

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-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 the old igniter out without touching the new element with bare fingers.
5. Install — Mount the new igniter, install the supplied wiring kit, and reconnect per your photo.
6. Test — Restore power, run a heat cycle, and confirm the igniter glows and the burners light.

Signs You Need a Replacement

• Furnace blower runs but burners never light (no-heat call).
• Igniter does not glow during the ignition sequence.
• Visible crack, chip, or white-spotting on the element.
• Multimeter reads open / infinite resistance across the igniter terminals.
