International Comfort Products N9MPD060F12A2 Limit Switch
Limit switches are crucial due to the fact that if the air never warms up inside the exchanger then the house will never get warm enough. A normal limit switch has a sensor located in the furnace that senses, or governs, when the air is warm enough to activate the main blower.
Major indications to watch for in a bad critical limit switch
- The heating and cooling system refuses to kick in or run like it should
- The whole system starts to runs spotty on more than one occasion
