Carrier 50TFF004 Limit Switch
One big reason why limit switches are designed that way is because if the air is not warm enough the you will lose all the heat as the air flows through the ducts. The limit switch is a type of sensor switch in the heating area that can determine when the air is warm enough that it can be circulated throughout the house.
Simple indications of a bad limit type switch
- The heating and cooling system will not begin the ignition sequence nor will it stay running longer than a minute
- Your system starts to behave erratically often
