Carrier 24ACA424A0030010 Limit Switch
The main reason limit switches are made is due to the fact that if the air inside the furnace is too cool then you will never get hot air through the ducts. A normal limit switch is a switch located in the furnace that can determine when the air is warmed to a point that it can be circulated throughout the house.
Major indications of a deteriorating limit switch
- The whole system begins to behave differently time after time
- The heating and AC system refuses to kick in or continue to run even though max temp has not been reached
