ICP Hot Surface Ignitor Electrode for RGS300SFEA0AAAA – OEM Igniter | Ships Today

Overview

This is the genuine OEM ignitor electrode, ICP part number 1179966, for ICP, Tempstar, and Heil gas furnaces. The igniter is the heart of the ignition sequence: on a call for heat the control board energizes the electrode, which glows hot enough to light the burner gas. Igniters are a wear item — the brittle element cracks with thermal cycling and eventually fails open, leaving the furnace unable to light. Symptoms include a furnace that cycles the inducer and gas valve but never ignites, or one that locks out after several failed ignition attempts.

Specifications

Compatibility

Direct-fit OEM replacement for the ICP / Tempstar / Heil RGS300SFEA0AAAA furnace and other RGS-family models that originally shipped with part 1179966. Confirm against your unit's parts breakdown before ordering.

Installation Guide

1. Safety First – Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter. Shut off the gas supply.
2. Access – Remove the burner compartment door.
3. Document – Photograph the igniter position and wiring routing before removal. Never touch the new element with bare fingers — skin oils shorten its life.
4. Remove – Unplug the igniter connector and remove the mounting screw(s), then withdraw the old igniter.
5. Install – Seat the new igniter in the same position, secure it, and reconnect the harness per your photo.
6. Test – Restore gas and power, then run a heat cycle and confirm the igniter glows and lights the burners.

Signs You Need a Replacement

• Furnace runs the inducer and opens the gas valve but never ignites
• Igniter element is cracked, blistered, or no longer glows
• Repeated ignition lockouts after several attempts
• No continuity across the igniter when tested cold
