Overview
This OEM hot surface igniter (electrode assembly, part number 1179966) is the ignition source for the ICP Tempstar/Heil RGS300LFFA0AAAA gas furnace. On every call for heat the control board energizes the igniter, which glows white-hot to light the gas at the burners. A cracked, carbon-fouled, or electrically open igniter is among the most common causes of a furnace no-heat lockout. Typical failure symptoms include the furnace failing to light, repeated ignition retries, a gas valve that clicks with no flame, or the system locking out after several attempts. The silicon carbide / silicon nitride element is brittle and wears with every cycle, so it is considered a routine replacement part.

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 wire harness routing before disconnecting anything.
- Remove — Unplug the igniter connector, remove the mounting screw, and carefully withdraw the old igniter, handling it only by the ceramic base.
- 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, run a heat cycle, and confirm the igniter glows and the burners light promptly.
