Carrier 38YCS048 Limit Switch
The main reason limit switches are made is because if the air is too cool inside the furnace to begin with, the you will lose all the heat as the air flows through the ducts. A normal limit switch contains a sensor in the heat exchanger that senses, or governs, if and when the air is actually warm enough for the main blower to kick in and circulate the air.
Major symptoms of a weakening limit switch
- The HVAC system refuses to kick in or will not stay running even though the desired temperature has not been attained
- The system starts to act weird more often than not
