MODELS 427 AND 427R SEALED SYSTEM
COMPONENT ACCESS AND REMOVAL:
An attempt has been made to arrange these instruc-
tions in such a way as to simulate which components
would need to be removed first in order to gain access
to other components. When following a component
removal procedure, it may be necessary to reference
another removal procedure towards the front of this
section.
NOTE: Always replace the filter-drier when servicing
the sealed system.
Upper and Lower Wine Storage Evaporator Access
and Removal (Models 427 & 427R)
The wine storage evaporators are mounted to the rear
wall in each wine storage compartment with Phillips-
head screws.
(See Figures 6-59)
NOTE: See SHARP EVAPORATOR FINS CAUTION at
beginning of this section .
Before accessing and removing a wine storage evapo-
rator, evacuate the refrigerant from the sealed system.
Then, remove the wine racks. Remove the evaporator
fan cover mounting screws and the evaporator fan
cover. Remove the evaporator cover mounting screws
towards the bottom of the evaporator cover. Rotate the
side of the evaporator cover farthest from the false wall
out slightly and push the compartment thermistor elec-
trical leads and rubber grommet from the slot in the
evaporator cover. Locate the ground wire riveted to the
back of the evaporator cover with a screw securing it to
the rear wall. Extract the ground screw and continue
rotating the side of the evaporator cover farthest from
the false wall out until the flange behind the false wall
clears the false wall. Pull the evaporator cover out, and
extract the evaporator mounting screws. Now, cut the
evaporator inlet and outlet tubing and pull the evapora-
tor out.

ning of this section.
To access and remove the refrigerator evaporator fan
assembly, you must first remove the evaporator fan
cover mounting screws and the evaporator fan cover.
