Tripp Lite SRXCOOL12K Limit Switch
A limit switch was crafted due to the fact that if the air never warms up inside the exchanger then you will never get hot air through the ducts. A normal limit switch is a type of sensor switch in the heat exchanger that makes the determination if and when the air is actually warm enough for the main blower to kick in and circulate the air.
Major symptoms of an ailing critical limit switch
- The heating and cooling system will not even start or run longer than 10 minutes
- The HVAC system begins to initiate and then stops on a regular basis
