Carrier FV4BNF002000 Limit Switch
A normal limit switch is a type of sensor switch in the heating area that senses, or governs, when the heated air is warmed to a point to activate the main blower. Limit switches are built because if the air is not warm enough then the house will never get warm enough.
What are some hints that my chief limit switch needs replacing?
- The HVAC system begins to become inconsistent more than once
- Your Carrier system will not start or continue to run for any length of time
