ICP Hot Surface Igniter Electrode for RGS240STAA0AAAA — Direct-Fit | Ships Today

Overview

This OEM hot surface igniter electrode (part #1179966) provides the ignition source for the gas burners in the ICP/Tempstar/Heil RGS240STAA0AAAA gas/electric rooftop unit. When the control board calls for heat, the igniter draws current and glows red-hot to light the gas at the burner. Because the silicon-carbide or silicon-nitride element is brittle and degrades with every heating cycle, igniters are a frequent wear item. A cracked or burned-out igniter is the leading cause of no-heat calls. Installing a genuine OEM-spec igniter restores dependable, fast ignition and proper furnace sequencing.

Installation Guide

1. Safety First — Disconnect power at the breaker and shut off the gas supply; verify zero voltage with a multimeter.
2. Access — Remove the burner-compartment service panel.
3. Document — Photograph the igniter position and wiring before disconnecting.
4. Remove — Unplug the igniter lead, remove the mounting screw, and carefully withdraw the brittle element without touching the surface.
5. Install — Mount the new igniter handling it only by the ceramic base, then reconnect the lead per your photo.
6. Test — Restore gas and power, call for heat, and confirm the igniter glows and lights the burners.

Signs You Need a Replacement

• No heat — burners never ignite
• Visible crack, chip, or burned-out spot on the element
