Electrical Principle
The pushbutton control switch starts and stops the
refrigeration cycle. Once the pushbutton control switch
is pressed, the compressor and fan should run. In
addition, a light located inside the button will illuminate,
which indicates that the machine is on. Once the
pushbutton control switch is pressed again, the
refrigeration cycle will stop, and the light will go out.
Under no circumstances should the pushbutton
control switch be pressed repeatedly.
This will
cause the compressor start and stop, thus causing
possible damage to the compressor and other
electrical components.
The start and run capacitors are located in the terminal
box. These components are used in conjunction with
the compressor. Once the pushbutton control switch is
placed in the ON position, power will travel to the start
capacitor to get the compressor started. After the
compressor has started, the run capacitor takes over
to keep the compressor running.
