Carrier 50RQ Limit Switch
A normal limit switch contains a sensor in the heating area that determines when the heated air is actually warm enough to activate the main blower. Limit switches were created because if the air is too cool inside the furnace to begin with, then the house will never get warm enough.
Major clues critical limit switch is dying
- System will not initiate or continue to run as it should
- The Carrier system is beginning to runs uneven time after time
