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 (4 °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 (4°C default)
LED Indicator Issues

Download data and clear the data log. If light

internal data log; download data and contact
Phononic Customer Care.

Interior Concerns
I don't feel air flow inside the unit
This cold-walled system doesn't require a fan to
circulate air to unify temperatures. If the walls are
cold to the touch, then it’s working.
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 humidity will cause
condensation to form on the walls.
Door doesn't close/closes
incorrectly
Check to make sure something isn't blocking it from
closing completely.
