Method for operating a laundry treatment apparatus, wherein the apparatus comprises: a laundry treatment chamber for treating laundry using process air; a control unit having an associated memory, a blower for circulating the process air within the laundry treatment chamber; a heating device which is provided for heating the process air; and at least one temperature sensor (27, 28, 29); the method comprising: detecting by said temperature sensor (27, 28, 29) at least one temperature signal indicative of the temperature of the ambient where the laundry treatment apparatus is located; characterized by selecting a predetermined speed profile for operating the laundry treatment chamber and/or the process air blower in dependency of the at least one temperature signal detected by said at least one temperature sensor (27, 28, 29) said predetermined speed profile being retrieved by the control unit from a plurality of speed profiles stored in the memory and starting to operate the laundry treatment chamber and/or the process air blower in a laundry drying cycle by applying or executing the selected predetermined speed profile to the laundry treatment chamber and/or to the process air blower during the drying cycle in dependency of the at least one detected temperature signal, wherein the selection of the predetermined speed profile comprises: comparing the detected temperature signal with a predetermined threshold temperature (T threshold); and applying a first cycle speed profile to the laundry treatment chamber and/or to the process air blower, whether the detected temperature signal exceeds said predetermined threshold temperature (T threshold); or applying a second cycle speed profile to the laundry treatment chamber and/or to the process air blower whether the detected temperature signal is below said predetermined threshold temperature (T threshold). detecting by said temperature sensor (27, 28, 29) at least one temperature signal indicative of the temperature of the ambient where the laundry treatment apparatus is located; characterized by selecting a predetermined speed profile for operating the laundry treatment chamber and/or the process air blower in dependency of the at least one temperature signal detected by said at least one temperature sensor (27, 28, 29) said predetermined speed profile being retrieved by the control unit from a plurality of speed profiles stored in the memory and starting to operate the laundry treatment chamber and/or the process air blower in a laundry drying cycle by applying or executing the selected predetermined speed profile to the laundry treatment chamber and/or to the process air blower during the drying cycle in dependency of the at least one detected temperature signal, selecting a predetermined speed profile for operating the laundry treatment chamber and/or the process air blower in dependency of the at least one temperature signal detected by said at least one temperature sensor (27, 28, 29) said predetermined speed profile being retrieved by the control unit from a plurality of speed profiles stored in the memory and starting to operate the laundry treatment chamber and/or the process air blower in a laundry drying cycle by applying or executing the selected predetermined speed profile to the laundry treatment chamber and/or to the process air blower during the drying cycle in dependency of the at least one detected temperature signal, wherein the selection of the predetermined speed profile comprises: comparing the detected temperature signal with a predetermined threshold temperature (T threshold); and applying a first cycle speed profile to the laundry treatment chamber and/or to the process air blower, whether the detected temperature signal exceeds said predetermined threshold temperature (T threshold); or applying a second cycle speed profile to the laundry treatment chamber and/or to the process air blower whether the detected temperature signal is below said predetermined threshold temperature (T threshold).
