TROUBLESHOOTING
Before contacting a service technician, your local product dealer or
Unique Off-Grid Appliances, please check the following points.
If you contact a technician to repair a fault listed below, or to repair a
fault caused by misuse, abuse, or faulty installation, a charge will be
made even if the appliance is under warranty.
PROBLEM
SOLUTION
Appliance is
connected
to power,
but does not
operate
• Check if 12V or 24V DC is present at the appliance.
If not, check all connections and the system
battery voltage.
• Check that the polarity is correct: positive (+)
is connected to positive (+), and negative (-) is
connected to negative (-).
• Check the fuse. If blown, replace with a new one
(see page 11 for details).
• The primary problem with a non-functioning
appliance is due to a voltage drop to the
compressor, which causes the unit to fail to start
due to “low voltage”. Typically a connection is
not as tight as it should be, or the wire size to the
compressor is too small. The low voltage problem
occurs instantly at start-up and can be difficult to
detect with a volt meter because it happens so
quickly (<100ms)
• If the appliance was turned off using the power
button, press the same button to restart
Appliance is
operating, but
the interior
(cabinet) is not
cold
• Allow the appliance at least 4 hrs to cool down
once turned on.
• Check that the thermostat control is turned to
the correct setting relevant to the room/ambient
temperatures.
• Check that the room/ambient temperature is not
approaching the internal operating temperature
and does not exceed to 100˚F (38˚C).
• Has too much warm food been added to the
freezer recently? If so, it will take some time for
the appliance to return to temperature.
• Does the cabinet have adequate ventilation
around the side walls, allowing it to transfer heat
properly? (See Installation section)
The lid will not
open
• Has the lid just been opened? If so, leave the
appliance closed for a few minutes to allow the air
pressure to equalize and try again.
