Freezer Evaporator (Models 611, 650)
NOTE: When replacing the evaporator, the filter-drier
must also be replaced.
NOTE: Evaporator fins are sharp and could cause
minor personal injury.
The freezer evaporator is attached at the ceiling of the
freezer compartment. (See Figure 7-73) After captur-
ing the refrigerant from the sealed system, remove the
defrost heater from the evaporator. Now, extract the
screws which secure the evaporator to the ceiling of the
freezer compartment. Pull the evaporator down, un-
braze or cut the evaporator inlet and outlet tubing, and
pull evaporator from compartment.
Freezer Heat Exchanger (Models 611, 650)
NOTE: When replacing a heat exchanger, the filter-drier
must also be replaced.
NOTE: When moving unit, floor must be covered to pro-
tect against damaging the floor.
To remove the heat exchanger, the compressor area
and evaporator area will need to be accessed. Then,
after capturing the refrigerant from the sealed system,
pull the unit from its installation (see previous WARN-
ING). Now, remove the unit shroud and rear duct.
Then, disconnect the defrost heater electrical leads and
extract the screws which secure the evaporator to the
ceiling of the freezer compartment. Pull the evaporator
down, un-braze or cut the heat exchanger from the
evaporator inlet and outlet, and pull evaporator from
compartment. Then, 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. Now, pull the heat exchanger out of
the heat exchanger hole. (See Figures 7-71 & 7-73)
NOTE: When replacing the heat exchanger, it is recom-
mended to attach it at the evaporator end first, then
feed the heat exchanger out through the heat exchang-
er 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.
