Trane SWT3623 Cut Out 322838-754 Typical culprits include voltage surgesThe Trane SWT3623 Low Pressure Cut Out is a critical safety control designed specifically for high efficiency refrigeration and air conditioning circuits. This OEM Trane pressure switch functions as a fail safe, stopping the compressor when suction pressure drops below the 250 PSI open setpoint. By monitoring refrigerant levels, it prevents the compressor from operating in a vacuum or under lubricated conditions, which typically lead to motor burnout.
