Overview

This OEM igniter electrode (Part Number 1179966) is the ignition source for the ICP / Tempstar / Heil RGS181LDAA0AGAA gas furnace. On each heating call the igniter heats up and lights the burners, then the system proves flame and continues the cycle. A cracked, eroded, or open igniter is one of the most common no-heat failures: the furnace attempts ignition, fails to light, and locks out. The ceramic element is brittle and degrades with thermal cycling, making it a normal wear item.
