ICP Hot Surface Igniter Electrode for RGS243LFFA0AAAA — Furnace Ignition | Ships Today

Overview

This genuine OEM igniter electrode (part number 1179966) is the ignition source for the ICP / Tempstar / Heil RGS243LFFA0AAAA gas furnace. On each heat call the control board sends voltage to the igniter, which glows red-hot and lights the gas at the burners. Igniters are a common wear item — repeated heat cycling makes the element brittle until it cracks or fails to reach temperature. When that happens the furnace tries to ignite, fails, and locks out, leaving the home without heat.

Specifications

Compatibility

A direct OEM fit for the ICP RGS243LFFA0AAAA and equivalent Tempstar, Heil, Comfortmaker, and Carrier-family gas furnaces using this igniter. Confirm the mounting bracket and connector match your existing igniter before installing.

Installation Guide

1. Safety First — Disconnect power at the furnace switch and breaker and verify zero voltage with a multimeter. Shut off the gas supply.
2. Access — Remove the burner compartment service panel.
3. Document — Photograph the igniter position, bracket, and wire routing before disconnecting.
4. Remove — Unplug the igniter connector and remove the mounting screw(s). Handle the old element by the ceramic base only.
5. Install — Mount the new igniter without touching the element with bare fingers, then reconnect per your photo.
6. Test — Restore gas and power, start a heat cycle, and confirm the igniter glows and the burners light.
