ICP Hot Surface Igniter Electrode for RGS240LFAA0AGAA — OEM 1179966 | Ships Today

Overview

This OEM igniter electrode (part number 1179966) is the ignition component for the ICP/Tempstar/Heil RGS240LFAA0AGAA gas furnace. On each call for heat the igniter heats to incandescence and lights the burner gas as the gas valve opens. When it fails, the furnace runs its inducer and steps through the ignition sequence but the burners never light, producing a no-heat condition or repeated ignition lockouts. Igniters are a normal wear item that degrade over thousands of cycles, and a direct OEM replacement restores dependable startup.

Specifications

Compatibility

Engineered as a direct OEM fit for the ICP family RGS240LFAA0AGAA gas furnace, including the Tempstar and Heil branded equivalents built on the same platform. Confirm your model and serial tag before ordering.

Installation Guide

1. Safety First — Disconnect power at the furnace switch and breaker, and verify zero voltage with a multimeter before touching any component.
2. Access — Remove the furnace burner-compartment service panel.
3. Document — Photograph the igniter wiring and mounting orientation before disconnecting.
4. Remove — Unplug the igniter lead and remove the mounting screw; handle only by the ceramic base, never the fragile element.
5. Install — Mount the new igniter in the same position, reconnect the lead, and confirm it sits correctly in the burner flame path.
6. Test — Restore power and run a heat cycle to confirm the igniter glows and the burners light.

Signs You Need a Replacement

• Furnace clicks or cycles but burners never ignite
• Visible cracks or breaks in the igniter element
• Repeated ignition lockouts or limited retries
• No-heat calls after the inducer and gas valve sequence
