Trane TWR030C100A4 Limit Switch
Limit switches are crucial due to the fact that if the air never warms up inside the exchanger then you will never get hot air through the ducts. The limit switch has a sensor in the heat exchanger that decides if and when the air is warm enough for the air to begin normal home circulation.
Signs of a dying main limit switch
- The system is starting to ramp up but then stops time after time
- The heating and AC system will not begin the ignition sequence nor will it stay running like it ought to
