The following things do not indicate breakdown
 You may hear the noise of water flowing.
This noise comes from the refrigerant circulating around the cooling system. Even
when the compressor is not working, there may be a flowing noise.
 The external door may become heavier or impossible to open
immediately after being shut.
The air that entered into the freezer is cooled down rapidly, so the pressure inside it
becomes lower than that outside temporarily.
Do not try to open the door forcibly and wait for some time.
 Condensation appears on the surfaces of the appliance.
This happens in a condition of high humidity, when the doors are opened and closed
frequently, or when the stored materials have high moisture levels. Wipe it off with a
dry cloth.
 The front and sides of the appliance are warm or hot.
The front and sides of the appliance contain built-in hot pipes that radiate heat and
reduce condensation on the outer walls. The temperature of stored materials is not
affected by the regular functioning of these pipes.
 The alarm goes off after putting in or taking out materials.
