In a method for determining a temperature of a revolving drum of a laundry dryer, said drum has an outer wall and thereon at least one strip-shaped delimited detection region comprising thermochromic material having a transition temperature in the range of a temperature that is to be expected and to be determined. Optical detection means arranged adjacent to the revolving part are configured, in particular as a reflected light barrier, to detect the color transition of the thermochromic material in the event of the transition temperature being exceeded or undershot. At the revolving drum the thermochromic material or, if appropriate, the color transition thereof is detected by means of the detection means. A temperature of the drum is then determined as corresponding to the transition temperature in such a way that the temperature thereof is determined as corresponding to one of the two temperature ranges below the transition temperature or above the transition temperature.
