Carrier 38YCC060 Limit Switch
A normal limit switch is a type of sensor switch located in the furnace that decides when the air is warm enough to activate the main blower. One big reason why limit switches are designed that way is due to the fact that if the air inside the furnace is too cool the you will lose all the heat as the air flows through the ducts.
Subtle cues of a poorly working limit type switch
- System is unable to start or run well like it is supposed to
- The HVAC system is beginning to erratically on more than one occasion
