Description
The Trane SWT04530 Reverse Flow Switch is a genuine OEM HVAC safety switch engineered to monitor airflow direction and protect your system from operation under undesirable conditions. Designed for use in compatible Trane and American Standard furnaces and air handlers, this reverse flow switch detects abnormal airflow — such as air moving in the wrong direction due to blockages or fan issues — and opens the circuit to prevent unsafe operation. It is set to open at 130 °F and close at 120 °F, ensuring consistent, reliable performance in temperature-triggered safety applications.
