Trane SEN2128 Liquid Level Sensor & Gasket 2.2"

The Trane SEN2128 is a liquid level sensor together with a gasket which is an essential part that is manufactured for use by Trane HVAC systems with refrigerant lines. It protects the system from the refrigerant charge level inside the liquid line. This sensor works in the same way as a switch and triggers an alarm to the control board of the system in case the refrigerant level is low. However, they also commonly result in low refrigerant level which may suggest a leak or a malfunction. Through proper refrigerant charge, the Trane SEN2128 sensor keeps off the danger of damaging the compressor through starvation and offers the better cooling performance.
