  • the present invention relates to an appliance comprising a temperature sensor and at least one position sensor of an element of the appliance.
  • It relates generally to the field of household appliances used to dry a product, including a dryer or a washer-dryer.
  • the measurement of the temperature in the drum is carried out so as, for example, to regulate the temperature in the drum according to a drying program selected by a user.
