Trane 2TWR1018A1000AA Limit Switch
The limit switch is a switch located in the furnace that decides when the air is warmed to a point for the main blower to kick in and circulate the air. One big reason why limit switches are designed that way is due to the fact that if the air inside the furnace is too cool then you will never get hot air through the ducts.
Major signs of a weak limit switch
- The system is beginning to act differently on a regular basis
- System will not initiate or will not stay running for any length of time
