Carrier 58CVX09010016 Limit Switch
The limit switch is a switch in the heating area that decides if and when the air is actually warm enough for the main blower to kick in and circulate the air. The reason limit switches exist is due to the fact that if the air never warms up inside the exchanger the you will lose all the heat as the air flows through the ducts.
How do you know if your limit switch has to be replaced?
- The Carrier system begins to ramp up but then stops frequently
- The heating and cooling system will not begin or run for any significant length if time
