Frost And/Or Dew Occur; Refrigerator Cools Overly; Door Is Not In A Horizontal State; Abnormal Operating Sound Is Generated - Hitachi R-B6800T User Manual

When this happens

Frost and/or dew occur

Frost and/or dew adhere
to the refrigerator interior
or the frame of the
drawer compartment.
Dew adheres to the outside of the
refrigerator (exterior, door seal,
door and drawer compartment etc).
Dew condensation
occurs in the Refrigerator
Compartment
Dew condensation
occurs in the Vegetable
Compartment

The door or the drawer compartment may not be closed completely.
Check whether the drawer compartment or the door has been closed completely after closing them.
The door may be opened/closed frequently or door may remain open for a long time.
Reduce frequency of opening and closing the door or open/close the door quickly.
A lower setting of the condensation prevention heater may cause dew condensation in the swing partition, door packing, or a door itself when humidity is high.
Dew may adhere to the those parts when the indoor humidity is high (ex: rainy day).
Frost and/or dew may adhere to the refrigerator interior or the door frame when the warm air outside comes in
contact with those parts.
Wipe off with a dry cloth.
Condensation may form on the wall and/or around the cold air blowout port
when the door is opened and closed frequently or the humidity is high around
the refrigerator.
Wipe the dew off with a dry cloth.
The humidity in the Vegetable Compartment is higher than other compartments. (To prevent vegetables from
drying and to make them last longer)
If it is undesirable that dew adheres to the stored vegetables, wrap them with the plastic fi lm.
Water may drop into cases placed in the Vegetable Compartment due to dew concentration.
Wipe off them with a dry cloth.
MAX. is selected in the temperature setting.
The surrounding temperature is lower than 5˚C.
refrigerator may cool overly. Switch the temperature setting to MIN. .
Do not place any food in front of the cold air blowout port.
The installation site may not be level. Left side or right side of the door may be slightly lower when the left or
right leg is sunk in the fl oor surface because of the soft fl oor material and the addition of food weight.
This does not affect the refrigerator performance. Adjust the refrigerator adjustable mount to keep it level if
you want to correct it. Pg.36
Lay the fi rm board which has more than 1cm thickness on the fl oor if the refrigerator itself inclines.
It is because air entered the Refrigerator Compartment is rapidly cooled and the pressure in the Refrigerator
Compartment temporarily lowers.
Another door may open for a moment by the wind pressure because cool air path connects each compartment.
The refrigerator may not be installed properly.
Possible Cause
You may feel that the operation sound is large because the compressor operates in high-speed under the following conditions: the refrigerator
does not cool fully on the occasion such as using it for the fi rst time, opening/closing the door frequently, the surrounding temperature is high.
The sound becomes small after cooling fully.
The compressor operates at low speed at night, for long vacations or absences, potentially developing large vibrations.
It is because the compressor operates in low-speed for conserving energy.
It is because the system changes the operating power of the refrigerator according to the temperature change.
The following sounds are generated when the refrigerator is operating normally, so they do not indicate any trouble.
Type of sound
Sound like water fl owing (trickling)
Sound like collision (tapping)
Sound like water boiling (bubbling up)
Sound like meat roasting (sizzling)
Sound like squeaking (cracking)
(knocking)
Sound like something is caught (clacking)
Sound like roaring (honking)
Sound caused immediately after closing the door
(booming)
Sounds caused by the Automatic ice maker
(zooming)
(rattling)
(clunking)
Sound occurred sometimes (clacking)
Hot air may come from the bottom of the refrigerator to exhaust the heat generated when the cooling device operates.
The temperature may rise to 50 – 60 ˚C immediately after installation or during summer.
It does not pose safety or performance problems, but avoid touching it.
Please check. This is the cause.
Switch it to MID. .
When the ambient temperature is low, the inside of the

Install it fi rmly.
These sounds are caused when the refrigerant fl ows or water fl ows/
evaporates to remove frost.
This sound is caused because the parts squeaks when the
refrigerator temperature changes.
These sounds are caused when the electric parts to control
the refrigerator temperature operates.
These sounds are made when ice is separated from the ice tray of the
auto ice maker or water is supplied to the ice tray. These sounds are
also heard every two or three hours when the water supply container is
empty. To stop the sound, touch the
