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. Therefore, if the condenser fan is running,
then the compressor should also be running. If the fan is running without the compressor
running, then this indicates either a problem with the compressor, the power supply to the
compressor or the safety overload protection has been tripped. If the latter is the case, then
switching the unit off for fifteen minutes, then on again, should solve the problem.
•
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:
•
THERMOSTAT CONTROL:
Is the thermostat 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.
•
ICE BUILD-UP ON INSIDE WALLS:
Under certain circumstances, ice may start to form on
the inside walls. If this build-up continues, it will reduce the unit’s ability to function correctly.
Factors causing this build-up are: humidity, high ambient temperatures and the thermostat set
too low. The condition is also exacerbated by frequent opening of the cover, or the cover
being left open too much. In the event of ice build-up, first empty the unit and allow the ice
time to thaw, then try running the unit at a slightly higher setting (lower number on the knob).
