ELECTRICAL
SYSTEM
THE RELATED COMPONENTS
The
wiring
diagram
located on the cabinet back
or behind the
grille
depicts
the electrical
system for that
model. All electrical components
are
grounded
to the cabinet.
The
green
center
conductor
in the
power
cord is attached
to the cabinet
to
provide
a
grounding
circuit
when the
cord
is
plugged
into
a
properly grounded
outlet.
After making a
replacement
of
an electrical component,
always
make
sure
the
ground
wire is reconnected.
The
electrical
outlet should be checked
to make
sure
it is
properly
wired.
Check
the outlet
with a circuit tester.
COMPR^ESSOR
TESTING THE COMPRESSOR
DIRECT
Testing the compressor with
no
other
wiring in the circuit is called the direct
test
method. The relay and overload
protector
must
be
removed in order to
perform
this
test. lt is recommended
that
a compressor
tester illustrated below. be used
to make
this test.
The tester leads
are
marked RUN, START,
and COMMON. Connect
the
common
lead
to the
common
terminal of
the
compressor,
the
start
lead to the
start
terminal
and
the run lead to
the run
terminal.
The
compressor
terminal
arrangements are
illustrated below. The
other two
leads
are
for
a start
capacitor
(if
used). When not in use, attach
the two
leads together and
place
the toggle switch
in the OFF
position.
Make
sure
there are
no bare leads touching
the cabinet. Plug
in the
tester
and
flip the
switch
to the start
position.
As
soon as
the compressor
starts,
release the
switch
to the
run
position.
lf the
compressor
is operative,
it
will continue
operating on the run
windings. lf the compressor fails
to run,
the compressor
is defective and must be
replaced.
