5. Completely close the door and make sure that stored food is not obstructing the door
6. Adjust the installation position to make enough space around the appliance

Problem: The appliance contains a bad smell

Reason:

1. Is the fridge or freezer temperature set to ‘Warm’?
2. Did you put in food with a strong smell?
3. Vegetables or fruit may have spoiled in the drawer?

Solution:

Problem: It is difficult to open the appliance door

Reason: Did you open the door right after you closed it?

Solution: If you try to open the appliance door within one minute after you closed it, you may have difficulties because of the pressure inside the appliance. Try to open the appliance door again in a few minutes so that the internal pressure stabilizes

Reason:

1. Did you store hot food without cooling it first?
2. Did you leave the appliance door open?
3. Do you open and close the appliance door frequently?

4. Remove the object on top of the appliance

Problem: The side or front of the appliance is warm

Reason: There are anti condensation pipes fitted to these areas of the appliance to reduce condensation forming from around the door area

Solution: The heat releasing pipe to prevent condensation is installed on the front and side of the appliance. You may feel it particularly hot right after the appliance is installed or during the summer. You can be assured that this is not a problem and is quite normal

Problem: There is water inside or outside of the appliance

Solution: Normal Operation

Problem: Rattling nosies

Reason:

1. Rattling noises may come from the flow of refrigerant, the water line on the back of the unit (for plumbed models only), or items stored on top of or around the appliance
2. Appliance is not resting evenly on the floor
3. Appliance with linear compressor was moved while operating

Solution:

1. Normal Operation
