Overview

This is the OEM igniter electrode (part 1179966) for the ICP / Tempstar / Heil RGS243HFAA0AAAA gas furnace. The hot surface igniter is the ceramic-element electrode that heats to a glowing temperature on each call for heat and lights the burner gas. It is a high-wear, brittle component: thermal cycling eventually cracks the element or causes it to lose continuity, which leaves the furnace locked out with no ignition. This direct-fit OEM electrode restores reliable, fast light-off. Specs: factory hot surface igniter electrode matched to the RGS243 burner assembly.
