An ambient light detection unit for a household appliance includes a sensor housing and a brightness sensor which is disposed in the sensor housing and detects the brightness of the ambient light in the environment. The ambient light detection unit has a lens with which the ambient light that is incident on the sensor housing is focused toward the brightness sensor. A household appliance is also provided.

A household refrigeration appliance has a thermally-insulated body with an interior container that delimits a coolable interior space, a refrigeration circuit for cooling the coolable interior space and at least one fan. During the proper operation of the household refrigeration appliance, the fan is operated in a closed loop speed-controlled manner according to an at least indirectly specified desired rotational speed of the fan. During an inspection mode, the fan is operated without closed loop speed control, the actual rotational speed of the fan is ascertained and the actual rotational speed is evaluated in order to detect an abnormal operating state of the fan.
