Description
The Trane SWT01263 Thermal Limit Switch Board monitors and protects the unit from excessive temperature conditions. It opens the electrical circuit when the temperature reaches approximately 210F shutting down the burner or heating operation and then automatically resets and closes it once the temperature drops to around 180F. Mounted on or near the heat exchanger or air path it supports the prevention of overheating caused by restricted airflow, blower failure, or system imbalance. In furnace applications, it works as an essential component to maintain controlled operation in HVAC systems.
