Abstract (en)

[origin: EP2843118A1] The invention relates to a method of operating a compressor (14) 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 (14) adapted to circulate a refrigerant (6) through the heat-pump system during a laundry drying operation and wherein the laundry treatment apparatus comprises a control unit (51) controlling the operation of the laundry treatment apparatus. In case that the operation of the compressor (14) is suspended, the operation of the compressor (14) is restarted upon receiving a restarting signal. The value of power or current (I_comp) supplied to the compressor (14) after restarting the compressor operation is monitored and the compressor operation is maintained or suspended again in dependency of the monitored value of power or current (I_comp). Further the invention relates to a laundry treatment apparatus adapted to implement the method.
