SETTING THE THERMOSTAT:

The thermostat regulates the temperature of the refrigerator. It
is calibrated by numbers, "1" being the warmest setting and "7"
being the coldest setting.
Start with the thermostat at a setting midway between the
warmest and coldest setting. After unit has reached a steady-
state temperature, adjust as necessary to maintain desired
temperature. Do not make large adjustments. Adjust by small
increments and let cool before readjusting.
Understand that, should you load your refrigerator excessively
with warm food, it may take a very long tome to cool down. To
avoid this "hot pull-down" condition, pre-cool food, or add only
small amounts of warm food at a time.
unnecessary work by the cooling system and save on your
energy usage.

POSSIBLE CAUSE
The supply voltage is outside of the set range.
The fan loads the electronics unit with more than 1A.
The rotor is jammed.
The pressure difference in the cooling system, is too high.

If the cooling system overloaded, the minimum speed of the
motor of 1850 RPM can not be maintained.
If the cooling system is loaded too heavily or the
temperature is set too high, the electronics can overheat.
