Carrier Z6 Limit Switch
Limit switches are built because if the air is not warm enough then you will never get hot air through the ducts. The limit switch is a switch in the heating area that senses, or governs, when the air is actually warm enough for the main blower to kick in and circulate the air.
Signals of a declining limit type switch
- The HVAC system is beginning to shut down unexpectedly on a regular basis
- The heating and cooling system is unable to start or run well longer than a minute
