Trane 2TWR1060A1000AA Limit Switch
The limit switch is a type of sensor switch in the heat exchanger that makes the determination when the heated air is warmed to a point that it can be circulated throughout the house. Limit switches exist because if the air is not warm enough then you will never get hot air through the ducts.
What are the indications that my limit type switch really is in need of a replacement?
- System will not begin the ignition sequence or will not stay running like it ought to
- The whole system begins to act differently occasionally
