Overview
This OEM hot surface igniter (electrode assembly, part number 1179966) is the ignition source for the ICP Tempstar/Heil RGS300LRAA0AAAA gas furnace. On each call for heat, the furnace control board energizes the igniter, which glows white-hot to ignite the gas at the burners. A cracked, carbon-fouled, or open igniter is one of the most common causes of furnace no-heat lockouts. Symptoms of failure include the furnace failing to light, repeated ignition retries, a clicking gas valve with no flame, or the system locking out after several attempts. Because the igniter element is brittle silicon carbide or silicon nitride, it degrades with every heat cycle and is treated as a wear item.

Compatibility
Engineered as the factory replacement igniter electrode for the ICP Tempstar/Heil RGS300LRAA0AAAA gas furnace. It also fits closely related RGS300 series models that share the same burner and ignition assembly. Always confirm your unit's model and serial tag matches before ordering.
Installation Guide
- Safety First — Disconnect electrical power at the furnace switch and breaker, and shut off the gas supply. Verify zero voltage with a multimeter before proceeding.
- Access — Remove the furnace burner compartment access panel.
- Document — Photograph the igniter bracket position and the wire harness routing before disconnecting anything.
- Remove — Unplug the igniter connector, remove the mounting screw, and carefully withdraw the old igniter. Handle only by the ceramic base — never touch the fragile element.
- Install — Mount the new 1179966 igniter, align it to the burner per your photo, secure the screw, and reconnect the harness.
- Test — Restore gas and power, then run a heat cycle and confirm the igniter glows and the burners light promptly.

- Furnace will not ignite or produces no flame on a call for heat
- Visible cracks, blisters, or carbon buildup on the igniter element
