ICP Hot Surface Igniter for RGS240SSAA0AAAA — OEM 1179966 Ignitor Electrode | Ships Today

Overview

This is the genuine OEM ignitor electrode (ICP part number 1179966) for the ICP/Tempstar/Heil RGS240SSAA0AAAA gas furnace. The hot surface igniter heats to a glowing temperature on every call for heat and ignites the gas at the burners. Because it is cycled through intense heat repeatedly and is inherently fragile, it is among the most common furnace failure points. A cracked or worn-out igniter will not reach ignition temperature, so the furnace fails to light and the home loses heat. Watch for the blower running with no warm air, a furnace that locks out after several tries, or a visibly cracked igniter element.

Specifications

Compatibility

Engineered as a direct-fit replacement for the ICP/Tempstar/Heil RGS240SSAA0AAAA gas furnace. This igniter is shared across many ICP-family RGS-series furnaces — confirm OEM number 1179966 against your existing part for guaranteed fitment.

Installation Guide

1. Safety First — Disconnect power at the furnace switch and breaker; verify zero voltage with a multimeter and shut off the gas supply.
2. Access — Remove the furnace burner/service panel.
3. Document — Photograph the igniter wiring and bracket position before disconnecting.
4. Remove — Unplug the igniter connector and remove the mounting screw; withdraw the old element without touching the new element's surface.
5. Install — Mount the new igniter, handling it only by the ceramic base, and reconnect the harness per your photo.
6. Test — Restore gas and power, start a heat cycle, and confirm the igniter glows and the burners light promptly.
