Customer Resolution
Unit doesn't power on
Check for proper installation of the power plug.
Unit's audible alarm doesn't sound when out of
temp range?
Did you just power up the refrigerator and is the system pulling down
to set point temperature? No alarm will sound until the set point is met
(5°C default).
Did you have a recent power failure and is the system pulling down to
set point temperature? No alarm will sound until the set point is met
(5°C default).
LED Indicator Issues

Data logging error but unit is operating normal
Download data and clear the data log. If light remains red there may
be another issue with the internal data log; download data and
contact Thermo Scientific Customer Care.

possibly there’s an issue with the backup battery power running low.
Replace it with a CR123A battery.

Interior Concerns
I have frost forming on the walls
Are you opening the door frequently? If so, the cooling system is
working hard to maintain the target set point and condensation may
freeze on the walls. It will thaw during the next defrost cycle. Run a
manual defrost cycle if desired.
I have condensation collecting on the walls
In a cold-wall system, high humidity will cause condensation to form
on the walls. If condensation is persistent, the provided desiccant bag
may need to be replaced.
Door doesn't close/closes incorrectly
Check to make sure something isn't blocking it from closing
completely.
Door alarm keeps sounding
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?
