Q
The cooling is weak.
A
When it is hot outside, its cooling capacity decreases due to the increase of the ambient
temperature.
When the dust filter gets blocked or warm outside air gets in, the cooling capacity will
decrease. So, make sure to clean the dust filter frequently, prevent heat loss by closing the
doors and insulate the cooling area by using curtains, blinds, shades or window tinting.
Q
The cooling is good generally. But, it gets weak when it is considerably hot.
A
It occurs when the outdoor unit is exposed to direct sun light and heat-up air is not
ventilated well. So, set up a sunblind over the outdoor unit and keep stuff away from the unit
to increase the ventilation.
When the cooling capacity decreases during a heat wave, clean the heat exchanger of
the outdoor unit or spray some cold water to the heat exchanger to increase the cooling
capability.
Q
The cooling is weak. Does it need refrigerant charging?
A
It is not correct charging refrigerant regularly. Except that you have moved in several times
or the connection pipes are broken, the refrigerant does not run low. So, when refrigerant is
additionally charged, it could be costly and cause a product's failure. When the refrigerant
leaks, all of it will escape in a short time resulting in cooling failure and no water coming
out of the drain hose. So, if water comes out from the drain hose, it indicates the normal
operation of the product and it does not need refrigerant charging.
Q
It fails to do cooling.
A
When the air conditioner is set to ventilation or the desired temperature is set higher than
the current temperature, it fails to do cooling. In this case, select cooling or set the desired
temperature lower.
Q
It floods the floor.
A
Place the drain hose properly. When it is not placed properly, the drain water would flow
back flooding the floor. So, straighten out the drain hose for the water to be drained well.
Q
Water drips at the drain connection (service valve) of the outdoor unit.
A
When a glass bottle is taken out of the refrigerator, moisture gets condensed on its surface
due to the temperature differences. The same principle applies to the air conditioner. When
cold refrigerant goes through the copper tube, moisture gets condensed on the surface
of the tube and the connection areas. To prevent the water condensation, the pipes are
insulated. But, the connection areas of the outdoor unit are not insulated for the purpose of
maintenance or repair, and water gets condensed due to the temperature differences and
drips down. Generally, it evaporates right away. But, when it drips much during muggy days,
put a water pan on the floor.
Q
It leaks even though a drain pump is used.
A
It occurs when the drain pump is plugged out or it is out of order. Check the power of the
drain pump and the position of the drain hose, and when the pump is faulty, contact the
drain pump manufacturer.
Samsung Electronics do not manufacture drain pumps. So, we are not able to correct the
drain pump problems.
Q
Whenever the air conditioner is turned on, it irritates my eyes and gives me a headache.
A
There are no components in the air conditioner irritating the eyes and sending out chemical
smells. But, when the air conditioner is turned on, other smell sources are sucked into the air
conditioner and get out of it. So find and root out the smell sources. Generally, it occurs at a
interior renovated place, a pharmacy, a gasoline handling place, a tire shop, a second-hand
book shop or an electronic component handling place, when its chemical or musty smells are
sucked in and sent out, it can be misled that the air conditioner generates them.
