Carrier 58DLA07010008 Limit Switch
A normal limit switch is a switch in the heating area that determines when the air is actually warm enough that it can be circulated throughout the house. Limit switches are crucial because if the air is too cool inside the furnace to begin with, then you will never get hot air through the ducts.
Important clues of a bad main limit switch
- The whole system starts to initiate and then stops repeatedly
- Your Carrier system will not begin or will not stay running longer that five minutes
