Freezer Evaporator (Models 632, 642)
NOTE:
When replacing the evaporator, the filter-drier
must also be replaced.
The freezer evaporator is attached to the rear wall,
located below the air duct/shelf, behind the ice bucket
area. After capturing the refrigerant from the sealed
system, remove the evaporator fan assembly and
defrost heater from the evaporator. Then remove the
lower light diffuser and the diffuser retainer. Now,
extract the screws which secure the evaporator to the
rear wall of the freezer compartment. Pull the bottom of
the evaporator up while rotating the heat exchanger
out, then remove the drain tube heater. Un-braze or cut
the evaporator inlet and outlet tubing, and pull evapora-
tor from compartment. (See Figures 7-74)
Freezer Heat Exchanger (Models 632, 642)
NOTE:
When replacing a heat exchanger, the filter-drier
must also be replaced.
NOTE:
Evaporator fins are sharp and could cause
minor personal injury.
NOTE:
It is not necessary to pull the unit from its instal-
lation in order to replace the heat exchanger. The heat
exchanger travels through the compartment ceiling to
the compressor area.
To remove the heat exchanger, the compressor area
and evaporator area will need to be accessed, and the
refrigerant captured from the sealed system. Then,
extract the screws which secure the evaporator to the
rear wall of the freezer compartment. Now, disconnect
all electrical leads above the evaporator. Pull the bot-
tom of the evaporator up while rotating the heat
exchanger out, un-braze or cut the heat exchanger from
the evaporator inlet and outlet, and pull evaporator from
compartment. Now, cut the suction line from the com-
pressor, and the capillary tube from the drier. Clear any
permagum from inside and outside of the heat
exchanger hole. Then, pull the heat exchanger down
out of the heat exchanger hole. (See Figures 7-71 and
7-74)
NOTE:
When replacing the heat exchanger, it is recom-
mended to attach it at the evaporator end first, then
feed the heat exchanger up through the heat exchanger
hole.
