ICP Ignitor Electrode for RGS243SFAA0AAAA — OEM Direct-Spark Igniter 1179966 | Ships Today

Overview

This OEM ignitor electrode (part #1179966) provides the spark ignition for the burner assembly in your ICP / Tempstar / Heil RGS243SFAA0AAAA gas furnace. The electrode delivers the high-voltage spark that lights the gas at the burner and, on many designs, also serves as the flame-sensing rod that confirms ignition to the control board. A cracked ceramic insulator, eroded electrode tip, carbon buildup, or a hairline porcelain fracture causes weak or no spark, failed ignition, short cycling, or repeated lockouts. Replacing the electrode restores reliable, on-demand ignition and proper flame confirmation so the furnace doesn't lock out on cold mornings.

Specifications

Compatibility

Direct OEM-fit replacement for the ICP / Tempstar / Heil RGS243SFAA0AAAA gas furnace and related Comfortmaker / Heil furnaces using this electrode assembly. Match the electrode bracket and rod geometry to your existing part before installing.

Installation Guide

1. Safety First — Disconnect power at the furnace switch and breaker; verify zero voltage with a multimeter and shut off the gas supply.
2. Access — Remove the furnace burner compartment door.
3. Document — Photograph the electrode position, gap, and wire routing before removal.
4. Remove — Disconnect the high-voltage ignition lead, unscrew the electrode bracket, and lift out the old electrode.
5. Install — Mount the new electrode, set it to the same gap and position, and reconnect the ignition lead per your photo.
6. Test — Restore gas and power, run a heat call, and confirm a strong spark, clean light-off, and stable flame sensing.

Signs You Need a Replacement

• Weak spark or no spark at the burner
• Furnace fails to ignite or locks out after retries
• Cracked or chipped ceramic insulator
• Short cycling or flame-sense faults on the control board
