Sealed System
The cooling system driven by the compressor incorporates a horizontally mounted
evaporator mounted in the top of the freezer compartment and a vertical condenser coil
mounted in the machine compartment. A post condenser loop (Yoder Loop) is used to
minimize cabinet sweating.
Refrigerant flow is from the outlet of the compressor to
the condenser. After the condenser the liquid refrigerant
flows through the Post Condenser (PC) loop around the
freezer door opening and back to the machine
compartment. The PC loop empties into a filter / drier
and supplies liquid refrigerant to the capillary tube. The
capillary tube is part of the heat exchanger that crosses
into the evaporator compartment and empties into the
evaporator coil. From the evaporator coil the gas returns
through the heat exchanger to the inlet of the
compressor.
The filter drier is mounted vertically with the inlet at the
top. It is critical to maintain proper positioning for both
effectiveness and noise reduction. When performing any
sealed system service the filter drier must be replaced.
The condenser and compressor can be pulled into a
service position by removing two screws, one on either
side of the condenser coil, and extending the equipment tray out of the front of the
machine compartment. To avoid damage to the PC loop, it is essential that the loop
entrance to the cabinet is supported and the condenser outlet is flexed to allow room for
the tray to be extended. If sealed system service is to be performed, do not remove the
grounding wire on the right side of the equipment tray until after connections have been
cut.
In this service position with the grounding wire still in place it is possible to service the
condenser fan. The condenser fan motor is the only motor in the system powered directly
by 120VAC.
The evaporator coil is accessed through the top of the freezer compartment. After
removing the contents of the freezer and the upper shelves or icemaker, depending on
model, remove the freezer light lens. Remove four screws and the light mounting panel
and you will have access to the evaporator fan and electronic damper. After the damper
and fan motor are removed there are four more screws retaining the fan shroud. Once the
