Customer Resolution
Check for proper installation of the power plug.
Did you just power up the refrigerator and is the system
pulling down to set point temperature? Alarm will not sound
until the set point is met.
Did you have a recent power failure and is the system pulling
down to set point temperature? Alarm will not sound until the
set point is met.
The red LED is active whenever there is an alarm. It can be
cleared by clearing the alarm.
Power loss
No action required
Are you opening the door frequently? If so, the cooling system
is working hard to maintain the target set point and
condensation may form on the walls. It will thaw during the
next defrost cycle.
Check to make sure something isn't blocking it from closing
completely.
Check to make sure the door is properly aligned in the frame
by looking for uneven surfaces. For example, is the gap from
the hinge to edge equal in width all the way across the
surface?
Is the power ON? Is the LED on front a solid green? If so, the
unit is powered and operating normally. Once the refrigerator
reaches its set point temperature then it will be very quiet
during normal operating conditions.
Has the temperature risen recently? Is the front free & clear for
proper ventilation? If you've recently held the door open for an
extended period of time or you put warmer product in the
refrigerator then the unit is likely recovering to its set point
temperature. Only be alarmed if you hear abnormal fan
sounds.
Once the unit displays 5°C, you are safe to start loading. If
loading with room temperature product, we recommend
loading the refrigerator in small increments to avoid raising the
temperature above the controlled temperature zone.
