Abstract

A method is provided for controlling a drying cycle of a laundry dryer having a laundry drum and an air stream fan for circulating drying air through said laundry drum. The method includes the steps of: starting a drying cycle (); performing the drying cycle (); detecting an electric resistance and/or conductivity of the laundry during the drying cycle () for estimating a dryness level of the laundry; comparing the electric resistance and/or conductivity of the laundry with an end cycle condition (); and finishing the drying cycle (), if the end cycle condition () is fulfilled. The end cycle condition () depends on the rotation speed (S) of the laundry drum and/or on the rotation speed (S) of the air stream fan.
