Carrier 58MSA100 Limit Switch
A normal limit switch contains a sensor in the air handler that decides if and when the air is actually warm enough for the main blower to kick in and circulate the air. Limit switches are crucial due to the fact that if the air inside the furnace is too cool then the house will never get warm enough.
Elements to watch for in a bad limit type switch
- The heating and cooling system refuses to kick in or continue to run for any significant length if time
- The whole system is starting to shut down unexpectedly time after time
