Internal temperature too high


If the internal temperature of the Refrigerator, freezer and refrigerator - freezer is too high, refer to the suggestions below for step by step instructions.

Is your appliance fitted with a fan?
  • If the fan is turned off, the temperature difference between the top and bottom of the refrigerator will be greater.
  • If the fan is switched on, this produces the most effective and uniform cooling of the air flow.
  • The temperature at the bottom may be lower, while the temperature at the top may be higher.

If the fan is not working:

Switching on the fan:

  • Switch the fan on, if possible. This is usually done by pressing a button on the fan housing, located inside the refrigerator or on the control panel.
  • Some refrigerators have a display showing a fan icon, indicating whether the fan is switched on or off.
  • You will find detailed information about fan settings in the user manual. (If you do not have your user manual, refer to Where can I find the user manual for my appliance?).
  • You can check the fan by closing the door and opening it again quickly after a moment.
  • When you open the door, you will be able to hear the air flow, which will stop after a few seconds.
  • The fan normally switches off when the door is opened.
If you have recently stored a large amount of food: 
  • If you store a large amount of food inside the appliance at once, the temperature will rise, which may activate the alarm.
  • It takes a few hours for the temperature to return to normal.
  • If the appliance can be set to shopping mode, you should enable this mode. This will boost the refrigeration when more food is placed in the refrigerator. See the user manual for details of how to enable shopping mode. (If you do not have your user manual, refer to Where can I find the user manual for my appliance?).
Is the temperature on the middle shelf below 4-6°C?

You can adjust the temperature either on the control panel or by turning the temperature control dial.

Adjusting the temperature:

  • Adjust the temperature by turning the temperature dial or via the control panel.
  • See the user manual for details of how to adjust the temperature. (If you do not have your user manual, refer to Where can I find the user manual for my appliance?).
  • To check that the cabinet is refrigerating correctly, place a glass of cooking oil inside the refrigerator overnight.
  • Use a thermometer to measure the temperature of the oil. If the temperature is between +4°C to +6°C, the cabinet is working correctly.
  • To check a freezer’s temperature, you need to use cooking oil instead of water.
Is the cabinet 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. This will activate the alarm on the display, the warning LED or an acoustic alarm. This alarm is normal, and indicates the temperature in the appliance is not optimal. The alarm will turn off after the cabinet has been at normal ambient temperature for a few hours and the set temperature has been reached.

  • You can turn off the acoustic alarm by pressing any button.
  •  See the user manual for details of how to turn off the acoustic alarm.
  •  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 closed correctly? Or 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 and activate the alarm. 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 can trigger the alarm on the display, the warning LED or an acoustic alarm.

  • 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.
  • This will also help save energy and protect the environment
  • 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).

Note: Do not heat the door seal too much, or you might damage both the seal and the door.

The compressor switches on and off at short intervals:

Does not refrigerate and compressor switches on and off at intervals of one to two minutes.

  • Switch off the cabinet for about 30 minutes and then switch it back on again.
  • If this does not fixed the problem, request a visit by a service engineer.
Loud clicking noise:
  • Does not refrigerate and the compressor makes a loud clicking noise, request a visit by a service engineer. 
Compressor does not operate at all:
  • Does not refrigerate and compressor does not run at all, request a visit by a service engineer.
Compressor very hot:

Does not refrigerate and, if you can hear the compressor running but the compressor is very hot (in the case of a freestanding cabinet), request a visit by a service engineer. (Report error code: IS).

Damaged hinges:
  • To resolve any issues with damaged hinges, we recommend requesting a visit by a service engineer. (Report error code: IM).



To help you determine the exact nature of the problem, we recommend a visit by one of our authorized engineers to check the appliance and fix the problem.
