5.The set temperature is not inputted properly.

6.The freezer is in the direct sunlight.

7.There is any heating source near the freezer.

8.A rubber cap and insulation for the access port are not set correctly.

9.You put too many unfrozen articles into the freezer compartment.

When the unit does not accept changes of set-point temperature

1.The key lock is set in “ON” mode.

Noise

1.The freezer is not installed on the sturdy floor.

2.The freezer is not leveled with the leveling feet.

3.There is anything touching the frame.

4.The freezer is in the status immediately after start up.
