Overview
This is the OEM igniter electrode (OEM part #1179966) for the ICP / Tempstar / Heil RGS243HDAA0AAAA gas furnace. The igniter is the component that heats up and lights the burners at the start of every heat cycle. Igniters are brittle and degrade over time from repeated thermal cycling — micro-cracks, carbon buildup, or a broken element are extremely common no-heat causes. When the igniter fails, the furnace runs its inducer and opens the gas valve but never lights, then locks out on a failed-ignition fault. Replacing the igniter with the correct OEM electrode restores dependable, on-the-first-try burner light-off. Handle the new igniter only by its ceramic base — skin oils can create hot spots that shorten its life.

Compatibility

Installation Guide
- Safety First — Disconnect power at the switch and breaker; verify zero voltage at the igniter connector with a multimeter, and shut off the gas supply.
- Access — Remove the burner-compartment service panel to reach the igniter at the burner assembly.
- Document — Photograph the igniter's position and bracket orientation before removal.
- Remove — Unplug the igniter harness connector, remove the mounting screw(s), and carefully withdraw the old igniter without touching the element.
- Install — Mount the new igniter in the factory position (handling it only by the ceramic base) and reconnect the harness per your photo.
- Test — Restore gas and power, start a heat call, and confirm the igniter glows and the burners light on the first attempt.
Signs You Need a Replacement
- Furnace locks out on failed ignition — inducer runs but burners never light.
- Igniter does not glow, or glows weakly/unevenly.
- Visible cracks, breaks, or heavy carbon on the igniter element.
- Delayed ignition with a noticeable "whoomp" when the burners finally catch.
