Carrier 38TZA060 Limit Switch
The main reason limit switches are made is because if the warmed air is too cool the you will lose all the heat as the air flows through the ducts. The limit switch has a sensor located in the furnace that senses, or governs, if and when the air is actually warm enough for the air to begin normal home circulation.
General indicators that your limit type switch is on its last leg
- The HVAC system begins to act weird often
- The heating and cooling system is unable to start or continue to run like it should
