  • Shown on: Miele refrigerator display
  • Reason: the freezer compartment door has been open for 45 minutes

Door alarm in the manual

Miele’s fridge-freezer manual (KFNS 7734 D) describes the alarm that accompanies a door left ajar, without quoting F146. The compartment’s temperature readout gains an alarm symbol, a tone plays and the lamp inside flashes; closing the door clears everything. Pressing OK mutes it early, but it sounds again after about a minute if the door remains open. The alarm timing and the tone are both set in the further settings.
