    							4-2. Measures for Symptoms on Temperature
    TROUBLE DIAGNOSIS
    - 111 -
    Problems Checks and Measures
    Refrigeration is weak.Check temperature set in the temperature control knob.
    • Refrigerator is generally delivered with the button set at “normal use” (MID). 
    But customer can adjust the temperature set depending on their habit and taste.
    If you feel the refrigeration is weak, then set the temperature control button at
    “strong” position. If you adjust the button in the freezer compartment as well, 
    the refrigeration is stronger than adjusting refrigerator only.
    The food in the chilled drawer is .The chilled drawer does not freeze food.
    not frozen but defrosted• Use chilled drawer for storing fresh meat or fish for short periods. For storing for
    a long periods or freezing food, use a freezer compartment.  It is normal that
    frozen foods thaw above the freezing temperature (in the chilled drawer).
    Refrigerator water is not cool.Check the water storage location.
    • If water is kept in the door rack, please ask to keep it in the refrigerator
    compartment shelf.  It will then become cooler. 
    Ice cream softens. Explain the characteristics of ice cream.
    • The freezing point of ice cream is below -15°C. Therefore ice cream may melt if
    it is stored in the door rack.
    • Store ice cream in a cold place or set the temperature control button of a freezer
    at “strong” position.
    Refrigeration is too strong.Check the position of temperature control button.
    • Check if refrigeration is strong in whole area of the refrigerator or partly near the
    outlet of the cooling air. If it is strong in whole area, set the control button at
    “weak”. If it is strong only near the outlet of cool air, keep food (particularly wet
    and easy to frozen such as bean curd and vegetables) away from the outlet.
    Vegetables are frozen.Check the vegetables storage.
    • If vegetables are stored in the refrigerator shelf or chilled drawer instead of
    vegetable drawer, they will be frozen. Set the control button at “weak” if they are
    also frozen in the vegetable drawer.
    The food stored at inside of Check if food is stored near the outlet of the cooling air. 
    the shelf freezes even the • The temperature at cooling air outlet is always below the freezing point. 
    control button is set at “MID”. Do not store food near the outlet of the cooling air as it block the air circulation.
    And do not block the outlet.  If the outlet of the cooling air is blocked, the
    refrigerator compartment will not be cooled.
     
    						
    							4-3. Odor and Frost
    TROUBLE DIAGNOSIS
    - 112 -
    Problems Checks and Measures
    Odor in the refrigerator compartment.Explain the basic principles of food odor.
    • Each food has its own peculiar odor. Therefore it is impossible to prevent or
    avoid food odor completely when food is stored in the completely sealed
    refrigerator compartment. Deodorizer can absorb some portions of the odor but
    not completely. The intensity of odor depends on refrigerator conditions and
    environments. 
    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”.
    Frost in the freezer compartmentExplain 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. 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.
    Frost in ice tray.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 shall freeze and form frost. If warm water was put into the ice
    mold, the situation will become worse.
     
    						
    							4-4. Others
    TROUBLE DIAGNOSIS
    - 113 -
    Problems Checks and Measures
    The refrigerator  case is hot.Explain the principles of radiator.
    • The radiator pipes are installed in the refrigerator case and partition plate
    between the refrigerator and the freezer compartment in order to prevent
    condensation formation.  Particularly in summer or after installation of
    refrigerator, it may feel hot but it is normal.  If there is no enough space to
    dissipate heat, it can be hotter due to lack of heat radiation. Please install a
    refrigerator in a well-ventilated place and leave a clearance between refrigerator
    and wall: 
    Small holes in a door linerExplain that the hole is for releasing gas.
    • A small hole in the door liner is for releasing gas during  insulation materials
    lining work.  With a releasing hole, forming can be easily done .
    Electric bills are too much.Check the use conditions.
    • Too frequent door opening and hot food storing cause the compressor to
    operate continuously and hence increase the electric consumption and bills.
    Condensation on the inside  Explain how to store foods
    wall of the refrigerator  • Condensation forms when refrigerator is installed at damp area, door is 
    compartment and the cover of  frequently opened, and wet foods are not stored in the air tight container or
    properly vegetable drawer. wrapped. Be sure to store wet foods in the air tight container or in the wrap.
    When is the power  connected?When should the power be connected ?
    • You can connect the power right after the installation.  But if the refrigerator was
    laid flat during transportation for a long period of time and the refrigerant and
    compressor oils are mixed up, then this will affect badly the performance of a
    refrigerator. Be sure to connect the power 2~3 hours after refrigerator is
    installed.
    Door does not open properly.Refrigerator compartment door does not open properly.
    • When the door is open, warm open air comes into the compartment and is 
    mixed up with cool air. This mixed air shall be compressed and increase the
    internal pressure when door is closed. This causes the door sticked closely to
    the refrigerator in a moment. (If the refrigerator is used for a long time, it will
    then open smoothly.)
    When the refrigerator compartment door is open and close, the freezer
    compartment door moves up and down.
    • When the refrigerator compartment door is open and close, fresh air comes into
    the freezer compartment and moves up and down the freezer compartment
    door.
    Door opens too easily.
    • There is a magnet in the gasket rubber so that it is ok. if door is securely closed
    without a gap.   It can be open easily if the foods in the refrigerator or freezer
    compartments hold the door open. 
    A door does not close properly. 
    • If the rear side of the refrigerator is raised higher than front side, door shall not
    be easily closed. Adjust the level of refrigerator with levelling screws.
    The front side should
    be raised a little bit higher
    than the rear side.
