The major components of the refrigeration system
are a reciprocating-type compressor, condenser,
condenser loop, dryer, and evaporator. These
components, except for the condenser loop, are all
replaceable separately.
Compressor
The compressor is a reciprocating type. Refer to
the mini-manual for the BTU/hour rating and the
compressor capacity test specification.
A copper process tube is provided for access to
the low-pressure side of the refrigeration system.
Note: The woodpecker clip holds the capillary
tube in thermal contact with the compressor
discharge tube. If the capillary tube is not clipped
to the discharge tube, a knocking noise may occur
during compressor operation.
Refer to the compressor replacement instructions
included with the replacement compressor.
Condenser
The condenser is located behind the grille panel at
the top of the refrigerator and is made of copper
tubing. The outlet of the condenser is connected
to a copper jumper tube that is connected to the
inlet of the condenser loop. In a normal home
environment, there is no need for routine
condenser cleaning. However, in environments
that may be particularly dusty or greasy, the
condenser should be cleaned periodically for
efficient refrigeration operation. An ordinary
appliance brush should be all that is needed.
Functionally, the condenser does the same job as
previous models. Air is drawn through the
condenser by the condenser fan from the front left
and rear left of the machine compartment. Air
exits only from the right side of the machine
compartment.
Condenser Loop
The condenser loop, made of copper tubing, is
foamed in place behind the breaker frame on the
freezer compartment side. It is not accessible for
replacement. The tubing is routed from the
machine compartment, forwarded to the mullion,
down to the freezer compartment, around the front
perimeter of the freezer, and back into the
machine compartment. The outlet of the
condenser loop is connected to the dryer inlet.
