Overview
This is the genuine OEM ignitor electrode (part number 1179966) for the ICP / Heil / Tempstar RGS243LEFA0AAAA gas furnace. The igniter electrode lights the burners at the start of every heat call. As it ages it cracks, carbons over, or loses the ability to reach ignition temperature, causing no-heat conditions, repeated ignition lockouts, or short-cycling on the gas valve. Replacing a failing igniter restores dependable, first-try ignition and eliminates nuisance no-heat callbacks. This is a direct-fit replacement that drops into the existing burner assembly without modification.

Installation Guide
- Safety First — Disconnect power at the furnace switch and breaker, and close the gas shutoff. Verify zero voltage with a multimeter.
- Access — Remove the furnace front service panel to expose the burner assembly.
- Document — Photograph the igniter wiring and mounting position before disconnecting anything.
- Remove — Unplug the igniter harness, remove the mounting screw(s), and carefully withdraw the ceramic igniter — handle only by the base, never the element.
- Install — Seat the new igniter in the same position, secure the screw(s), and reconnect the harness per your photo.
- Test — Restore gas and power, then run a heat cycle to confirm the igniter glows and the burners light on the first attempt.
Signs You Need a Replacement
- Furnace blower runs but burners never ignite (no heat).
- Visible cracks, chips, or white/gray buildup on the ceramic element.
- Furnace locks out after 3 ignition attempts and flashes an ignition-fault code.
- Igniter glows weakly, intermittently, or not at all during a heat call.
