ICP Hot Surface Igniter for RGS121HFCB0AAA — OEM 1171306 with Wiring Kit | Ships Today

Overview

This OEM hot surface igniter (part #1171306), supplied with the matching igniter wiring kit (#1188370), is the ignition source for the ICP/Heil/Tempstar RGS121HFCB0AAA gas furnace. When the thermostat calls for heat, the control board energizes the igniter; it glows orange-hot and lights the burners as the gas valve opens. Hot surface igniters are fragile and wear out with thermal cycling, making a cracked or weak element one of the most common no-heat failures. A genuine OEM igniter restores dependable first-try ignition and eliminates ignition lockouts.

Installation Guide

1. Safety First — Disconnect power at the furnace switch and breaker, shut off the gas, and verify zero voltage with a multimeter.
2. Access — Remove the furnace burner/service panel.
3. Document — Photograph the igniter mounting and wiring before disconnecting.
4. Remove — Unplug the igniter connector, remove the mounting screw(s), and lift out the old igniter without touching the element.
5. Install — Mount the new igniter, handling it only by the ceramic base, and connect the new wiring kit per your photo.
6. Test — Restore gas and power, run a heat cycle, and confirm the igniter glows and lights the burners on the first attempt.

Signs You Need a Replacement

• Furnace ignites intermittently or locks out on ignition failure
