Carrier 38TKB030 Limit Switch
A limit switch was crafted because if the air is too cool inside the furnace to begin with, then you will never get hot air through the ducts. The limit switch is a type of sensor switch in the heat exchanger that senses, or governs, if and when the air is warm enough for the blower to be activated.
Warnings of a poorly working limit type switch
- The system starts to behave differently occasionally
- Your Carrier system will not even start or run as it should
