Miele KF 9757 ID Compressor is switching in too frequently and for too long

Problem solving guide

. . . the compressor is switching in too frequently and for too long.

^Check whether the ventilation gaps in the plinth and in the housing unit at the top have been covered over or become too dusty.

^The doors have been opened too frequently, or a large amount of fresh food has been put in at once for freezing.

^Check that the doors have been closed properly.

^Check to see whether a thick layer of ice has built up in the freezer. If it has, then the freezer section will need defrosting.

. . . the compressor runs continuously.

To save energy, the compressor runs at a lower speed, but for longer, when less cooling is required.

. . . the frozen food is thawing because the freezer section is too warm.

^Is the room temperature lower than the ambient temperature for which the appliance is designed?

If so, raise the temperature of the room.

Operating in a room which is too cold will cause the cooling system to switch off for too long causing the freezer section to become too warm.

. . . food has frozen together.

Use a blunt instrument, e.g. a spoon handle or plastic scraper, to prise it apart carefully.

. . . there is a thick layer of ice in the freezer section.

^Check whether the freezer section door closes properly.

^Defrost and then clean the freezer section.

Too thick a layer of ice reduces efficiency and increases energy consumption.

^Close the door.

. . . the alarm sounds and the freezer section temperature display flashes.

The freezer section temperature has risen above the set temperature because

^the freezer section door has been opened too frequently, or large amounts of fresh food have been put in at once for freezing.

The alarm will stop and the temperature display will light up constantly again as soon as the temperature has dropped down to the correct level again.
