Overview
This OEM ignitor electrode (part number 1179966) is the factory-specified hot surface ignition component for the ICP / Tempstar / Heil RGS303HFFA0AAAA gas furnace. On each call for heat, the furnace control board energizes the igniter; it glows red-hot and lights the burners as the gas valve opens. The igniter is one of the most frequently replaced furnace components because the silicon-carbide/silicon-nitride element is brittle and degrades with every thermal cycle. Common failure symptoms include the furnace blower running but no flame, a clicking control board that locks out after three ignition attempts, a no-heat call on the coldest days, or a visibly cracked, white, or blistered igniter element. Replacing a weak igniter before it fails completely prevents an emergency no-heat call.

Installation Guide
- Safety First — Disconnect power at the furnace switch and breaker, shut the gas, and verify zero voltage with a multimeter.
- Access — Remove the lower service/burner panel.
- Document — Photograph the igniter bracket and the two-wire connector before disconnecting.
- Remove — Unplug the igniter harness, remove the mounting screw, and carefully withdraw the old electrode without touching the glow surface.
- Install — Mount the new igniter, handling it only by the ceramic base, then reconnect the harness exactly as photographed.
- Test — Restore gas and power, run a heat cycle, and confirm the igniter glows and lights all burners smoothly.
Signs You Need a Replacement
- Furnace blower runs but burners never light.
- Control board locks out after three failed ignition attempts.
- Igniter element is cracked, white, or no longer glows.
- Intermittent no-heat that worsens in cold weather.
