Carrier 50XP060300 Limit Switch
The limit switch has a sensor in the air handler that decides if and when the air is warmed to a point for the blower to be activated. The main reason limit switches are made is because if the air is too cool inside the furnace to begin with, then you will never get hot air through the ducts.
Clues of an ailing main limit switch
- Your Carrier system is unable to start nor will it stay running like it should
- The Carrier system is starting to stop suddenly from time to time
