HOUSEHOLD REFRIGERATION APPLIANCE HAVING A CLOSED LOOP SPEED-CONTROLLED FAN AND METHOD FOR OPERATING A HOUSEHOLD REFRIGERATION APPLIANCE HAVING A CLOSED-LOOP SPEED-CONTROLLED FAN

摘要

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.
