ICP Hot Surface Igniter Electrode for RGS303HRAA0AAAA — Silicon Nitride | Ships Today

Overview

This OEM hot surface igniter (part #1179966, IGNITOR ELECTRODE) is the direct-fit ignition component for the ICP/Tempstar/Heil RGS303HRAA0AAAA gas furnace. The igniter receives 120V from the control board on each call for heat, glowing white-hot to ignite the gas at the burners. As a silicon-nitride style hot surface igniter, it is more durable and resistant to thermal shock than older silicon-carbide elements. When this part fails, the furnace will not light — the most common no-heat complaint on this platform. A cracked or burned-out igniter is the #1 wear item in modern gas furnaces and should be handled only by the ceramic base, never the fragile element.

Specifications

Compatibility

Engineered for the ICP/Tempstar/Heil RGS303HRAA0AAAA furnace and shared-platform models across the ICP family (Comfortmaker, Arcoaire, KeepRite). Always confirm your existing OEM part number before ordering.

Installation Guide

1. Safety First — Disconnect power at the furnace switch/breaker and shut off the gas. Verify zero voltage with a multimeter.
2. Access — Remove the lower service/blower panel.
3. Document — Photograph the igniter bracket and wiring before disconnecting.
4. Remove — Unplug the igniter connector, remove the mounting screw, and lift the old element out — handle only by the ceramic base.
5. Install — Seat the new igniter, secure the screw, and reconnect the plug per your photo without touching the element.
6. Test — Restore gas and power, then run a heat cycle and confirm the igniter glows and the burners light.

Signs You Need a Replacement

• Furnace blower runs but burners never ignite (no heat).
• Visible crack, blister, or white burn spot on the igniter element.
• Igniter does not glow during the ignition sequence.
• Open circuit / infinite resistance when ohm-tested.
