TROUBLESHOOTING AND SERVICE GUIDE
The following is intended as a brief service guide, designed to diagnose most common problems.
It is intended to be used only as a guideline. Should the unit require replacement of components,
those components must be replaced by a trained and licensed refrigeration professional. While
the unit is within the factory warranty period, all repairs require factory authorization before the
work is performed.
UNIT NOT COOLING:
POWER TO THE UNIT: Is there power to the unit? Is the voltage within ± 10% of 115 VAC?
Low power conditions affect the amperage draw of the compressor, therefore requiring more
amperes at start up. If the amperage draw is too high, the compressor safety relay could trip,
leading to component premature failure. If the compressor is tripping on its safety relay at
startups, then the unit will not refrigerate as required.
COMPRESSOR NOT RUNNING: When the unit calls for cooling to begin, power is supplied to
the compressor and condenser fan simultaneously, but the power to the compressor is via a
time delay set to ten minutes. Therefore, the fan will run for ten minutes before the
compressor starts; this is normal.
CONDENSER FAN NOT RUNNING: Is the compressor running but not the condenser fan? If
the compressor is running, then the condenser fan should be running. Verify that power is
being supplied to the fan motor, and that the fan blades rotate freely. Check for debris
(leaves, paper, grass clippings, etc.) in the fan blades, these may prevent the fan from
rotating.
UNIT NOT HOLDING TEMPERATURE CORRECTLY:
EVAPORATOR INTAKE: Is the evaporator coil intake blocked by product? The evaporator
unit has been designed to prevent products such as bottles, cans or other rigid packaging from
blocking the intake. However, products in soft flexible packaging may still be positioned in a
way which blocks some, or all of the air intake slots. If the air intake slots are obstructed, then
products must be rearranged to clear the slots, thereby permitting air to be drawn into the
evaporator coil.
DIGITAL TEMPERATURE CONTROL: Is the control set correctly? Please refer to the
recommended settings in the user manual, and follow the instructions for setting the control. If
the thermostat is not set to suit the prevailing conditions, then the product may not be
refrigerated to your liking. The wrong setting may also cause condensation to form inside the
unit, or excessive ice to form in the evaporator coil, thereby blocking air flow through the coil.
