This OEM hot surface igniter/sensor (part number 1009524) lights the burners on your Tempstar TNE075F14B2 gas furnace. The silicon-nitride HSI element heats to ignition temperature within seconds when the control board calls for heat, igniting the gas as the valve opens. Hot surface igniters are a wear item: the element grows brittle with every heat cycle and eventually cracks or fails to reach temperature, leaving you with no ignition and no heat. This igniter also serves the sensing function (HSI/sensor), so replacing it with the exact OEM part restores both reliable ignition and proper flame confirmation.
