Carrier 50QT Limit Switch
A normal limit switch is a type of sensor switch in the heat exchanger that senses, or governs, when the air is warm enough so that it may be pushed through the ducts and out the vents. Limit switches are built because if the warmed air is too cool then you will never get hot air through the ducts.
Some warnings critical limit switch should need replacing
- Your system is starting to run erratically more than once
- The heating and AC system will not start or run well longer than 30 seconds
