Abstract

A method is provided for controlling a laundry dryer including a laundry drum (12) with a variable drum rotation speed (vd) and a drying air stream fan (18) with a variable fan rotation speed (vf). The method includes the steps of setting a course of the drum rotation speed (vd) or a course of a drum motor power (Pd) of the laundry drum (12), and setting a fan rotation speed (vf) and/or a fan motor power (Pf) of the drying air stream fan (18) on the basis of the drum rotation speed (vd) and/or the drum motor power (Pd) of the laundry drum (12). The fan rotation speed (vf) and/or the fan motor power (Pf) of the drying air stream fan (18) is decreased with an increasing drum rotation speed (vd) and/or increasing drum motor power (Pd) of the laundry drum (12). The fan rotation speed (vf) and/or the fan motor power (Pf) of the drying air stream fan (18) is increased with a decreasing drum rotation speed (vd) and/or decreasing drum motor power (Pd) of the laundry drum (12).
