TROUBLESHOOTING
Before contacting a service technician, your local product dealer or
Unique 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 9 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)
Appliance is
operating, but
the interior
(cabinet) is not
cold
• Allow the appliance at least 4 hours to cool down
once turned on.
• Check that the thermostat control knob 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
fridge/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)
