Refrigerator Evaporator
(Models 611, 632, 642, 650, 690)
NOTE: When replacing the evaporator, the filter-drier
must also be replaced.
NOTE: Evaporator fins are sharp and could cause
minor personal injury.
The refrigerator evaporator is attached to the rear wall,
behind the evaporator cover. After capturing the refrig-
erant from the sealed system, remove the screws which
secure the evaporator to the rear wall. Pull the bottom
of the evaporator up while rotating the heat exchanger
out. Now, un-braze or cut the evaporator inlet and out-
let tubing, and pull evaporator from compartment. (See
Figure 7-72)
Refrigerator Heat Exchanger
(Models 611, 632, 642, 650, 690)
NOTE: When replacing a heat exchanger, the filter-drier
must also be replaced.
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. Now,
extract the screws which secure the evaporator to the
rear wall, and pull the bottom of the evaporator up while
rotating the heat exchanger out. Un-braze or cut the
evaporator inlet and outlet tubing, and pull evaporator
from compartment. Then, cut the suction line from the
compressor, and the capillary tube from the drier. Clear
any permagum from inside and outside of the heat
exchanger hole. Now, pull the heat exchanger down
and out of the heat exchanger hole. (See Figures 7-71
and 7-72)
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.

One end of heat exchanger is connected to evapo-
rator. Evaporator fins are sharp. One end of heat
exchanger is connected to compressor and filter
drier. Compressor and tubing may be hot.
