Carrier 58DLA07010016 Limit Switch
A normal limit switch has a sensor in the air handler that decides if and when the air is warm enough so that it may be pushed through the ducts and out the vents. 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.
Signs of a weakening limit type switch
- The heating and cooling system will not start or will not stay running as it should
- The HVAC system starts to stop suddenly often
