Carrier 48XZ030040300TP Limit Switch
The limit switch is a type of sensor switch in the heat exchanger that can determine when the air is warmed to a point for the main blower to kick in and circulate the air. The reason limit switches exist is because if the air is not warm enough then the house will never get warm enough.
Symptoms of an ailing limit type switch
- System will not even start or run well longer that five minutes
- The system is beginning to behave erratically on a regular basis
