Refrigerator, freezer, refrigerator - freezer has a build-up of ice


If the refrigerator, freezer, refrigerator - freezer has a build-up of ice, please refer to the suggestions below.

Normal ice and condensation in freezer cabinets:
  • It is normal for frost and ice to form in freezers.
  • Ice forms when the door is opened, allowing humid air into the appliance.
  • This ice may be removed by defrosting the freezer.
Have you tried defrosting your freezer?

The freezer must be defrosted when the layer of ice on the sides reaches a thickness of about 10–15 mm. It will be easier to defrost the freezer when the freezer is empty or only contains a few items.

Is the food stored correctly?
  • Always store food wrapped in foil, or in an airtight box.
  • Food items which are left unwrapped will create a lot of moisture and ice inside the appliance.
Is the product adequately ventilated all the way round?

To ensure adequate cooling, the cabinet must be sufficiently well-ventilated.

  • Install the refrigerator in accordance with the instructions supplied with the cabinet.


Freestanding cabinets


The cabinet must be installed well away from heat sources such as radiators, boilers, direct sunlight, etc.

  • Make sure that air can circulate freely around the back of the cabinet. To ensure the best possible performance, if the cabinet is located under a wall cabinet, the distance between the top of the cabinet and the wall must be at least 100 mm.
  • However, it is recommended that appliance cabinets are not placed beneath wall cabinets.
  • Precise leveling can be ensured by adjusting one or more of the adjustable feet on the bottom of the appliance cabinet.

Integrated cabinets


Is the ambient temperature between 10°C to 32°C?

If the ambient temperature is too high or too low, cooling may be adversely affected.

  •  Check the temperature classification, which is stated on the data label.
  • Correct operation can only be guaranteed for SN class products within an ambient temperature range of 10 °C to 32 °C.

Specification of climate class on the rating plate:

2017-08-25_1114 (1).png
  • Class N = 16 - 32 °C
  • Class SN = 10 - 32 °C
  • Class ST = 18 - 38 °C
  • Class SN/T = 10 - 38 °C
Has the door been opened frequently or left open for a long time?

If the door has not been closed properly, the temperature in the appliance could get too high. Moisture or ice may also coalesce inside the appliance or the cabinet.

Is the door seal not fitted correctly? Or has it been damaged in any way?

If the door seal is damaged or not properly in position, the temperature in the cabinet will rise, or a lot of ice and condensation will form due to air outflow.

  • This indicates that the temperature inside the appliance is too high.
  • In the case of freestanding appliances, the rubber door seal can be inspected using a piece of paper. When the door is closed, the seal should grip the sheet of paper firmly and uniformly. In the case of integrated appliances, it is possible to perform this check by removing the wooden door of the kitchen unit.
  • If the door seal is deformed, it can be restored by heating it for a few seconds with a hair dryer and then attempting to straighten the rubber. Do not heat the door seal too much, as this will warp or damage both the seal itself and the appliance door.
  • Keep the door seal clean and replace it if there are any signs of damage.
  • If you are unable to replace the door seal yourself, we recommend requesting a visit by a service engineer. (To request a visit by one of our engineers, please refer to information below).
  • Accessories and spare parts are available from our Webshop. (You can visit our webshop by clicking on the link below).
