Overview
This OEM igniter electrode (part 1179966) is the ignition source for the ICP/Heil/Tempstar RGS300HSFA0AAAA gas furnace. On each heat call the control board sends voltage to the igniter, which heats to incandescence and ignites the gas at the burners. The igniter is one of the most common furnace wear items because the repeated heating and cooling cycles eventually crack or weaken the element. Typical failure symptoms include no ignition, the furnace locking out after several failed ignition attempts, a glowing igniter that never lights the burners, or short cycling on the heat call. Because the element is brittle, always handle the new igniter by its ceramic base — never touch the silicon nitride/carbide element with bare fingers.

Installation Guide
- Safety First — Shut off gas and disconnect power at the furnace switch. Verify zero voltage with a multimeter.
- Access — Remove the furnace burner compartment door.
- Document — Photograph the igniter position, bracket orientation, and wire routing before removal.
- Remove — Unplug the igniter connector, remove the mounting screw, and carefully withdraw the old igniter from the burner assembly.
- Install — Seat the new igniter at the correct depth and angle so the element sits in the burner flame path, secure the screw, and reconnect the plug. Do not touch the element.
- Test — Restore gas and power, then run a heat cycle and confirm the igniter glows and lights the burners promptly.
Signs You Need a Replacement
- Furnace will not ignite or fire the burners
