ICP Hot Surface Igniter Electrode for RGS243SRAA0AAAA | Ships Today

Overview

This is a genuine OEM igniter electrode (part number 1179966) for the gas heating section of the ICP/Tempstar/Heil RGS243SRAA0AAAA package unit. The igniter heats up on a call for heat to light the burners and establish the flame. Igniters are a common wear item — they are brittle and degrade with every heating cycle, eventually cracking or losing the ability to reach ignition temperature. When the igniter fails, the furnace section will lock out with no heat, you may hear the inducer and gas valve cycle without ignition, and the unit may try several times before going into a hard lockout. Replacing the igniter restores dependable, safe ignition each heating cycle.

Specifications

Compatibility

Directly fits the gas heat section of the ICP/Tempstar/Heil RGS243SRAA0AAAA. Verify the mounting bracket and connector match your existing igniter before installation.

Installation Guide

1. Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter; shut off the gas supply.
2. Access — Remove the burner/control access panel.
3. Document — Photograph the igniter position, bracket, and wiring before removing anything.
4. Remove — Unplug the igniter connector and remove the mounting screw(s); handle the old igniter by the ceramic base only.
5. Install — Mount the new igniter without touching the fragile element, reconnect the plug, and confirm proper alignment over the burner.
6. Test — Restore gas and power, call for heat, and verify the igniter glows and lights the burners on the first cycle.

Signs You Need a Replacement

• No heat — burners never light on a heat call.
• Furnace section goes into lockout after several failed ignition attempts.
• Visible cracks, chips, or white spots on the igniter element.
• Igniter glows weakly or not at all during the ignition sequence.
