Trane TCP048F100AB Limit Switch
A normal limit switch has a sensor in the heat exchanger that can determine when the air is warm enough that it can be circulated throughout the house. The main reason limit switches are made is because if the air is too cool inside the furnace to begin with, then the house will never get warm enough.
Major indications limit switch has to be replaced
- Your Trane system will not start or will not stay running for any significant length if time
- The whole system begins to runs uneven on more than one occasion
