Carrier 58MXB140F10120 Limit Switch
One big reason why limit switches are designed that way is because if the warmed air is too cool the you will lose all the heat as the air flows through the ducts. The limit switch contains a sensor in the heating area that can determine if and when the air is warm enough for the blower to be activated.
Signals limit switch will not live much longer
- The heating and cooling system will not start or will not stay running like it should
- The Carrier system is beginning to runs spotty time after time
