I have a sterling tf-45 heater that i need a high limit switch for, they are discontinued. I know the specs but i need help finding a replacement. Its a 5" two prong with a 175 open 145 close... help please and thanks!
Your best chances are with Sterling. Your furnace may not be made anymore however that limit switch could possibly still be used in other models. Otherwise you'll have to find a switch that's a close approximation in design to fit your mechanical space. The temperature limits should be easy to match.
