Nordyne MS3BC042KA Limit Switch
A limit switch was crafted due to the fact that if the air never warms up inside the exchanger the you will lose heat in the ducts and the vents will just blow cool air. A normal limit switch has a sensor in the heat exchanger that decides when the air is warm enough for the air to begin normal home circulation.
Simple warnings that your limit type switch really is on its last leg?
- The heating and AC system will not even start or run even though the desired temperature has not been attained
- Your system is starting to act differently from time to time
