Tempstar Hot Surface Igniter for T9MVX060F12A1 — OEM 1172533 HSI | Ships Today

Overview

This is the OEM hot surface igniter (HSI), part number 1172533, for the Tempstar T9MVX060F12A1 two-stage variable-speed gas furnace. The hot surface igniter glows red-hot on every heating call to ignite the gas at the burners. The element is brittle and, over many heat cycles, cracks or loses the ability to reach ignition temperature — the result is a furnace that runs but produces no heat. Watch for a unit that clicks and runs the inducer but never lights, repeated ignition lockouts, or an igniter that no longer glows. This OEM HSI restores reliable ignition without a costly service visit.
