ICP Hot Surface Igniter for RGS120LECB0AAA — OEM Kit with Wiring Harness | Ships Today

Overview

This OEM hot surface igniter assembly is the direct-replacement ignition source for the ICP/Heil/Tempstar RGS120LECB0AAA gas furnace. The kit pairs igniter part 1171306 with the matching igniter wiring kit 1188370, so you replace the brittle silicon-carbide/nitride element and its high-temperature lead in one job. When the furnace control board energizes the igniter on a call for heat, the element glows red-hot and ignites the gas at the burners. A cracked or worn igniter is one of the most common causes of furnace no-heat lockouts.

Compatibility

Engineered for the ICP-family RGS120LECB0AAA furnace and the Heil, Tempstar, and Comfortmaker units built on the same chassis. Always confirm your model and serial against the OEM part numbers above before ordering.

Installation Guide

1. Safety First — Shut off gas, disconnect power at the furnace switch and breaker, and verify zero voltage with a multimeter.
2. Access — Remove the furnace blower/burner access panel.
3. Document — Photograph the igniter mounting and wiring routing before disconnecting.
4. Remove — Unplug the igniter lead, remove the mounting screw(s), and lift the old igniter out without touching the element with bare fingers.
5. Install — Mount the new igniter, route and connect the new wiring kit, and confirm the element sits in the burner flame path per the photo.
6. Test — Restore gas and power, run a heat cycle, and verify the igniter glows and the burners light cleanly.

Signs You Need a Replacement

• Furnace clicks but never lights / no glow at the igniter.
• Visible cracks, blistering, or white spots on the element.
• Repeated ignition lockouts or short cycling on a call for heat.
• Igniter glows but burners fail to ignite reliably.
