Method of operating a compressor in a laundry treatment apparatus, in particular laundry dryer or washer-dryer, wherein the laundry treatment apparatus comprises: a heat-pump system having a compressor adapted to circulate a refrigerant through the heat-pump system during a laundry drying operation, and a control unit controlling the operation of the laundry treatment apparatus, wherein the method comprises: suspending the operation of the compressor, restarting the operation of the compressor upon receiving a restarting signal, wherein the compressor operation is restarted independent of any predetermined time delay after suspension of the compressor operation, and monitoring the value (I_comp) of power or current supplied to the compressor after restarting the compressor operation, and characterized by in dependency of the value (I_comp) of the power or current maintaining the compressor operation, if the monitored value (I_comp) of the power or current is lower than a predetermined value (I_thresh), and suspending again the compressor operation, if the value of the monitored power or current (I_comp) is equal to or is higher than the predetermined value (I_thresh), wherein in case of suspending again the compressor operation, a predetermined suspension time period (t_susp) is set, and the compressor operation is restarted a second time after expiry of the predetermined suspension time period (t_susp), and wherein the second-time restarted compressor operation is maintained and suspended according to the condition for the first time of restart of the compressor operation. a heat-pump system having a compressor adapted to circulate a refrigerant through the heat-pump system during a laundry drying operation, and a control unit controlling the operation of the laundry treatment apparatus, wherein the method comprises: suspending the operation of the compressor, restarting the operation of the compressor upon receiving a restarting signal, wherein the compressor operation is restarted independent of any predetermined time delay after suspension of the compressor operation, and monitoring the value (I_comp) of power or current supplied to the compressor after restarting the compressor operation, and characterized by suspending the operation of the compressor, restarting the operation of the compressor upon receiving a restarting signal, wherein the compressor operation is restarted independent of any predetermined time delay after suspension of the compressor operation, and monitoring the value (I_comp) of power or current supplied to the compressor after restarting the compressor operation, and characterized by in dependency of the value (I_comp) of the power or current maintaining the compressor operation, if the monitored value (I_comp) of the power or current is lower than a predetermined value (I_thresh), and suspending again the compressor operation, if the value of the monitored maintaining the compressor operation, if the monitored value (I_comp) of the power or current is lower than a predetermined value (I_thresh), and suspending again the compressor operation, if the value of the monitored power or current (I_comp) is equal to or is higher than the predetermined value (I_thresh), wherein in case of suspending again the compressor operation, a predetermined suspension time period (t_susp) is set, and the compressor operation is restarted a second time after expiry of the predetermined suspension time period (t_susp), and wherein the second-time restarted compressor operation is maintained and suspended according to the condition for the first time of restart of the compressor operation.
