Carrier 48JZ Limit Switch
Limit switches were created 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 has a sensor located in the furnace that can determine when the air is actually warm enough for the blower to be activated.
Easy warnings of a deteriorating critical limit switch
- The heating and AC system will not even start nor will it stay running longer than a minute
- The HVAC system is starting to become unpredictable often
