International Comfort Products N9MP1075B12A1 Limit Switch
Limit switches are built due to the fact that if the air inside the furnace is too cool the you will lose heat in the ducts and the vents will just blow cool air. A normal limit switch contains a sensor in the heating area that determines if and when the air is warmed to a point for the main blower to kick in and circulate the air.
Subtle hints limit switch has to be replaced
- The heating and cooling system will not initiate or continue to run like it is supposed to
- Your system is beginning to runs uneven time after time
