ICP Igniter Electrode for RGS240SDEA0AAAA — OEM Ignitor | Ships Today

Overview

This is the genuine ICP OEM igniter electrode (part number 1179966) for the RGS240SDEA0AAAA gas furnace. The igniter electrode produces the high-voltage spark or hot-surface ignition source that lights the burner at the start of every heat cycle. Because it endures repeated thermal cycling and exposure to combustion, the electrode tip eventually cracks, erodes, or develops carbon buildup that prevents reliable ignition. Typical failure symptoms include the furnace failing to light, multiple ignition attempts before the burner fires, a furnace that locks out on ignition failure, and short cycling on the heat call. Installing a fresh OEM electrode restores dependable, first-try ignition.

Installation Guide

1. Safety First — Shut off the gas supply, disconnect power at the furnace switch and breaker, and verify zero voltage with a multimeter.
2. Access — Remove the burner compartment service panel.
3. Document — Photograph the electrode position, gap, and wire routing before disconnecting.
4. Remove — Disconnect the ignition lead and unfasten the old electrode from its bracket near the burner.
5. Install — Mount the new electrode, set it to the factory gap, and reconnect the ignition lead per your photo.
6. Test — Restore gas and power, then start a heat call and confirm the burner lights on the first attempt.

Signs You Need a Replacement

• Furnace will not light on a heat call.
