of door.

●Condensation may appear on the surface of cabinet when humidity is

high, e.g. during rainy season or the air circulation is not good.

●If there is condensation inside, check if the door is completely closed.

Is the refrigerator frequently opened or left open for a long time?

Is there any hot foodstuff refrigerated inside?

The refrigerator

does not operate.

●Check that the plug and its socket are in good condition.

●Check if there is any problem on main fuse and electrical system of the

house.

●Check by unplug and wait for 5 minutes before plugging it back in.

The refrigerator

does not cool

enough.

●Check to be sure that the temperature control button / knob is at the

proper position.

●

Check to see if the refrigerator is overloaded with stuff or there

is any hot

foodstuff refrigerated inside.

●Is the refrigerator exposed directly to sunlight or heat source?

●Is the refrigerator door completely closed?
