ICP Hot Surface Igniter Electrode for RGS240LDAA0AAAA — OEM | Ships Today

Overview

This OEM igniter electrode (part number 1179966) provides the ignition source for the ICP/Tempstar/Heil model RGS240LDAA0AAAA furnace. On each heat call, the control board energizes the igniter, which heats to the temperature required to light the burner gas. Because the electrode is brittle and endures repeated thermal cycling, it is one of the most common wear items in a gas furnace. A cracked or worn igniter is a leading cause of no-heat conditions where the inducer and gas valve operate normally but the burners never light.

Specifications

Compatibility

Engineered as a direct OEM fit for the ICP/Tempstar/Heil RGS240LDAA0AAAA furnace. Compatible across ICP-family furnaces that share the same ignition electrode assembly. Confirm the mounting bracket orientation and connector style match your existing igniter before installing.

Installation Guide

1. Safety First — Shut off gas and disconnect furnace power, then 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 — Unplug the igniter connector and unscrew the mounting bracket. Handle the old igniter by the base, never the ceramic.
5. Install — Mount the new igniter without touching the element with bare fingers, then reconnect the harness per your photo.
6. Test — Restore gas and power, call for heat, and confirm the igniter glows and the burners light on the first attempt.

Signs You Need a Replacement

• Furnace runs the ignition sequence but burners never light (no-heat).
• Visible cracks, chips, or hot spots on the element.
• Igniter glows weakly or not at all during a heat call.
• Repeated lockouts after several failed ignition attempts.
