Description
The Trane SWT3927 is a genuine OEM limit switch used in HVAC systems to monitor temperature and protect equipment from overheating. Often installed in furnaces, air handlers, or heat exchangers, this limit switch opens or closes an electrical circuit when a specific temperature threshold is reached, helping to prevent unsafe operating conditions. The SWT3927 is designed with a L155 60°F rating, meaning it reacts to temperature changes within that range to control system operation and maintain safe performance. Built to Trane’s original manufacturer standards, it ensures consistent, long lasting service and reliable system protection.
