ICP Hot Surface Igniter for RGS303HREA0AAAA — Ignitor Electrode 1179966 | Ships Today

Overview

This OEM hot surface igniter (ignitor electrode, part number 1179966) is the direct-fit ignition component for the ICP / Tempstar / Heil RGS303HREA0AAAA gas furnace. The igniter is a 120V silicon-nitride/carbide element that glows red-hot on a call for heat, lighting the gas at the burner. It is one of the most common furnace wear items: every heat cycle thermally stresses the element until it cracks or loses resistance. Typical failure symptoms include no ignition, the furnace blower running with no heat, repeated lockouts after three or four ignition attempts, or a visibly cracked, blistered, or no-longer-glowing element. Replacing the igniter restores reliable single-attempt ignition and prevents nuisance furnace shutdowns.

Specifications

Compatibility

Engineered for the ICP family RGS303HREA0AAAA furnace and the matching Tempstar, Heil, Comfortmaker, and Arcoaire variants that share this gas-valve and burner assembly. Always confirm against your unit's parts list and the OEM number 1179966 before installing.

Installation Guide

1. Safety First — Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter. Shut off the gas supply.
2. Access — Remove the furnace burner-compartment service panel.
3. Document — Photograph the igniter bracket and wire routing before disconnecting.
4. Remove — Unplug the igniter connector, remove the mounting screw, and carefully withdraw the old element. Handle only by the ceramic base — never touch the element.
5. Install — Seat the new igniter at the correct depth, secure the screw, and reconnect the plug per your photo.
6. Test — Restore gas and power, then run a heat cycle and confirm the element glows and the burners light on the first attempt.

Signs You Need a Replacement

• Furnace blows cold air or never lights on a call for heat.
• Visible cracks, blisters, or white spots on the element.
• Igniter no longer glows during the ignition sequence.
• Repeated control-board lockouts after multiple ignition attempts.
