I Explain the basic principles of food odor.
• Each food has its own particular odor. Therefore it is impossible to prevent or
avoid food odor completely when food is stored in the completely sealed
refrigerator compartment. The deodorizer can absorb some portions of the odor
but not completely. The intensity of odor depends on refrigerator conditions and
environments.
I Check the temperature control button and set at strong.
• Clean inside of the refrigerator with detergent and remove moisture. Dry inside
the refrigerator by opening the door for about 3 or 4 hours and then set the
temperature control button at strong.
I Explain the basic principles of frost formation.
• The main causes for frosting:
- Door was left open.
- Air penetration through the gasket
- Too frequent door opening. (parties. etc.)
- Hot foods are stored before they are cooled down. The temperature of freezer
is -19°C (-2.2°F). if temperature is set at MID. If hot air comes into the
refrigerator, fine frost forms as cold air mixes with hot air. If this happens quite
often, much frost forms inside of the refrigerator. If the door is left open in
Summer, ice may form inside of the refrigerator.
I Explain basic principles of frost formation.
• When ice tray with full of water is put into a freezer compartment, the water
evaporates. If cool air fan operates, the moisture attached to the jaw (protruded
part) of ice mold will freeze and form frost. If warm water was put into the ice
mold, the situation will become worse.
