This OEM hot surface igniter assembly is the direct-fit ignition component for the ICP / Heil / Tempstar RGS121HTBA0AAAA gas furnace. The kit includes OEM ignitor part number 1171306 and the matching igniter wiring kit 1188370, giving you everything needed to restore reliable ignition. The hot surface igniter glows red-hot on each call for heat to ignite the gas at the burners. Because the element is brittle silicon carbide or silicon nitride, it is one of the most common furnace failure points — repeated thermal cycling, soot, and handling damage cause hairline cracks that interrupt the heating cycle. Typical failure symptoms include the furnace blower running with no heat, a clicking or repeated ignition attempt that ends in lockout, an igniter that no longer glows, or a system that short-cycles on a hard or warm restart.
