ICP Hot Surface Igniter Electrode for RGS240LSAA0AAAA — OEM 1179966 | Ships Today

Overview

The ICP igniter electrode (OEM part 1179966) is the ignition component responsible for lighting the burners in your RGS240LSAA0AAAA gas furnace. When a heat call is initiated, the control board energizes this igniter to create the heat or arc needed to ignite the gas at the burner assembly. A failed or cracked igniter is one of the most common causes of a furnace that runs the blower but produces no heat. This is a genuine OEM-spec replacement that matches the original electrical resistance and mounting geometry, ensuring reliable, repeatable ignition cycle after cycle.

Installation Guide

1. Safety First — Disconnect power at the furnace switch and breaker; shut off the gas supply and verify zero voltage with a multimeter.
2. Access — Remove the burner compartment service panel.
3. Document — Photograph the igniter position and wiring before disconnecting.
4. Remove — Disconnect the igniter lead and remove the mounting screw(s); withdraw the old electrode carefully without touching the ceramic element.
5. Install — Mount the new igniter, handling it only by the base, and reconnect the lead per your photo.
6. Test — Restore gas and power, then run a full heat cycle to confirm proper ignition and flame.

Signs You Need a Replacement
