Abstract: A method for drying laundry in a laundry dryer having a program control device, a drying chamber and a process air circuit includes providing a flow dividing device in the process air circuit for dividing the drying air flow into an exhaust air component and a recirculated air component. A sensor is used to measure a pressure in the process air stream in an area where the drying air enters the drying chamber. The pressure is evaluated and the flow dividing device is controlled based on the evaluation so as to reduce or set to zero the recirculated air component and to continue the drying process at a reduced volumetric flow rate of the drying air through the drying chamber.
