Carrier 58MVB100F10120 Limit Switch
The main reason limit switches are made is because if the air never warms up the you will lose all the heat as the air flows through the ducts. The limit switch has a sensor in the heating area that determines if and when the air is warm enough so that it may be pushed through the ducts and out the vents.
What are some hints that my critical limit switch has to be replaced?
- The system begins to initiate and then stops repeatedly
- System refuses to start or run longer that five minutes

If you are going to be buying or purchasing do your best and cross-check the model number as well as make a visual inspection in order to be sure the correct limit switch is the one being purchased. You do not have to install the replacement part alone. Search for a pro in your community to do the job for you.
