Overview

This OEM ignitor electrode (part 1179966) provides the ignition spark/surface for the ICP / Tempstar / Heil RGS243HEEA0AAAA gas furnace. On a call for heat, the igniter heats and ignites the gas at the burner. The electrode is a brittle, high-temperature component that degrades with every ignition cycle; when it cracks, erodes, or loses continuity the furnace fails to light, locks out after several attempts, or produces no heat. A fresh OEM electrode restores fast, reliable ignition and prevents nuisance lockouts.
