Carrier FX4BNB060000AAAA Limit Switch
Limit switches are crucial due to the fact that if the air never warms up inside the exchanger then the house will never get warm enough. A normal limit switch contains a sensor in the heat exchanger that makes the determination when the heated air is actually warm enough for the blower to be activated.
Some warnings of an inadequate limit switch
- The heating and cooling system refuses to kick in nor will it stay running like it ought to
- The system is starting to act weird frequently
