Description
The Trane SWT1432 Blocked Vent Switch is a genuine OEM safety component designed to monitor your furnace’s venting system and help protect your heating equipment from dangerous conditions caused by blocked or restricted flue airflow. When the vent temperature rises to a critical threshold, this switch opens the electrical circuit to safely shut down the furnace, helping prevent overheating and potential system damage.
