Carrier 50TFQ004 Limit Switch
The limit switch is a switch in the heating area that can determine when the heated air is warm enough for the main blower to kick in and circulate the air. One big reason why limit switches are designed that way is because if the air is too cool inside the furnace to begin with, the you will lose heat in the ducts and the vents will just blow cool air.
Elements of a defective limit switch
- System refuses to start or run like it is supposed to
- The system starts to become unpredictable on more than one occasion
