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.
