International Comfort Products T8MPT075F14B1 Limit Switch
The limit switch has a sensor in the heat exchanger that can determine if and when the air is warm enough so that it may be pushed through the ducts and out the vents. One big reason why limit switches are designed that way is due to the fact that if the air never warms up inside the exchanger the you will lose all the heat as the air flows through the ducts.
Simple indications of a poorly performing critical limit switch
- The HVAC system is beginning to act weird time after time
- The heating and cooling system will not begin or run well for any significant length if time
