TROUBLE SHOOTING
If the unit malfunctions, check out the following before calling for service.
No refrigeration
1.
The voltage is too low. (In this case, call an electrician.)
2.
The power is not supplied.
3.
The breaker is free.
Poor refrigeration
1.
The environmental temperature is high.
2.
The door is not shut tightly.
3.
The inner lid is not installed correctly.
4.
The set temperature in the controller is not set properly.
5.
The grille is blocked out.
6.
The filter is clogged.
7.
The freezer is in the direct sunlight.
8.
There is any heating source near the freezer.
9.
A rubber cap and insulation for the access port are not set correctly.
10.
You put too many unfrozen articles into the freezer compartment.
Noise
1.
The freezer is not stable.
2.
The freezer has not been leveled with the leveling feet.
3.
There is anything touching the frame.
4.
It is the first operation after shutdown.
High temperature loads this freezer, and sometimes causes a noise. Accordingly when the temperature
lowered, the noise ceases.
Alarm test key cannot actuate the power failure alarm
1.
The battery has been discharged entirely.
In this case, operate the freezer for about 3 hours and switch on the alarm test key again. Entirely
discharged cell requires about 2 days’ operation.
When only the buzzer or only the alarm is actuated by the alarm test key, the unactuated part is out of
order, and must be replaced.
Recorder does not operate normally
1.
If the chart was not fed, examine the dry cell. The cell for the recorder lasts about 1 year.
2.
If the temperature was not recorded, examine the recording pen.
The pen should be our specified one. Is the recorder chart set correctly?
