ICP Igniter Electrode for RGS243HRFA0AAAA – OEM Hot Surface Ignitor | Ships Today

Overview

This is the genuine OEM igniter electrode (part 1179966) for the ICP / Tempstar / Heil RGS243HRFA0AAAA gas furnace. The igniter electrode lights the gas at the burners at the start of each heating cycle. As the element ages it develops micro-cracks and high resistance, leading to no-heat calls, repeated ignition lockouts, or a furnace that clicks but never lights. Because the igniter is brittle, it should never be touched on the element surface and is the first component to check on a furnace that will not fire. Installing the correct OEM igniter restores reliable, on-demand ignition.

Installation Guide

1. Safety First – Disconnect power and shut off the gas; verify zero voltage with a multimeter.
2. Access – Remove the burner compartment service panel.
3. Document – Photograph the igniter position, bracket orientation, and wire routing.
4. Remove – Unplug the connector and remove the mounting screw, then withdraw the old igniter without touching the element.
5. Install – Seat the new igniter, secure the bracket, and reconnect the harness, handling it only by the ceramic base.
6. Test – Restore gas and power and confirm the burners light on the first ignition attempt.
