Carrier 58MXB120F10120 Limit Switch
The limit switch is a type of sensor switch in the air handler that senses, or governs, if and when the air is warmed to a point so that it may be pushed through the ducts and out the vents. The reason limit switches exist is because if the air is not warm enough the you will lose heat in the ducts and the vents will just blow cool air.
General indicators that your limit switch is on its last leg
- The heating and cooling system is unable to start or run well longer than 10 minutes
- Your system is beginning to initiate and then stops on a regular basis
