This OEM hot surface igniter (HSI) kit is the ignition component for the ICP Tempstar/Heil RGS121LDBA0AAAA gas furnace. When the furnace receives a call for heat, the control board energizes the igniter, which heats to roughly 1,800–2,500°F and lights the burner gas. The kit combines OEM igniter 1171306 with igniter wiring kit 1188370 so the element and its harness are replaced as a set for a dependable connection. A failed igniter is among the most common "no heat" failures — the inducer runs but the burners never light. Hot surface elements are brittle and wear out with each ignition cycle, making replacement routine furnace maintenance.
