ICP Hot Surface Igniter Electrode for RGS303LSEA0AAAA — Direct OEM Fit | Ships Today

Overview

The ICP OEM Igniter Electrode (part number 1179966) is the direct ignition component for the RGS303LSEA0AAAA gas furnace. This hot surface igniter heats to ignition temperature within seconds to light the burners on every heat call. When the igniter cracks, develops hairline fractures, or burns out, the furnace will fail to ignite, short-cycle, or lock out after repeated failed trial-for-ignition attempts. Installing the correct OEM electrode restores dependable, safe ignition and ends nuisance lockouts.

Specifications

Compatibility

Engineered as the factory ignition component for the ICP Tempstar Heil RGS303LSEA0AAAA gas furnace. This OEM electrode matches the original mounting bracket, connector, and gap, so no modification is required. Confirm your model number on the furnace rating plate before ordering.

Installation Guide

1. Safety First — Disconnect power at the furnace switch and breaker, shut off gas, and verify zero voltage with a multimeter.
2. Access — Remove the furnace burner-compartment service panel.
3. Document — Photograph the igniter wiring and bracket position before disconnecting.
