Figure 7-10.
To remove the icemaker evaporator assembly:
1. Disconnect refrigerator from electrical supply.
2. Remove all food section shelves.
3. Refer to pages 6-20 through 6-25 for removal of the
ice maker components needed to access the ice
maker sealed system components.
4. Disconnect wiring harness from EEV.
5. Cut suction line and cap tube at locations shown in
Figure 7-10.
6. Remove evaporator components from compartment.
7. Replace with new evaporator kit components.
8. Secure finger evaporator to ceiling of compartment.
9. Clean ends of suction line and cap tube that were
cut in step 5 with swag tool.
10. Cut a seam in heat shield 1/2 way through, then
slide cap tube and suction tube through the
opening.
(See Figure 7-8) Pack heat shield against ice maker
frame and liner.
11. Use the 1/4” and 5/16” copper tubing sleeves
included in the kit, and install over inlet and outlet
lines of the new evaporator. Insert the tubing into
the other end of the sleeve and weld in place.
12. Remove the heat shield.
13. Reinstall the ice maker components.
14. Replace filter-drier. Pump down and recharge
system.
Ice Maker Heat Exchanger
Replacement Finger Evaporator
Ice Maker Models
This unit has two heat exchangers (Suction Line & Cap
Tube Assembly) enclosed in the insulation between the
liner and the cabinet back. One heat exchanger is for
the freezer evaporator, the other heat exchanger is for
the ice maker evaporator located in the top left corner
of the food compartment. Because of this, the original
parts can not be removed. There is a service kit to
bypass the internal heat exchanger. It will be necessary
to run a new heat exchanger down the back of the
product and bypass the internal heat exchanger if the
heat exchanger has a leak or the cap tube is restricted.
Heat Exchanger Kit Contains:
1- Heat Exchanger
6- Screws
1- Filter-Drier
1- Cover
1- Armor Flex
1- Package Permagum
2- Tape
1- Instruction Sheet
To replace the ice maker heat exchanger:
1. Disconnect refrigerator from electrical supply.
2. Remove all freezer section shelves.
3. Remove evaporator cover.
4. Disconnect wiring harness at liner plug.
5. Cut suction line in front of weld at evaporator. Using
a file, score and break the cap tube just in front of
the weld. (See Figure 7-8 )
6. Remove ice maker from unit.
7. Connect new heat exchanger to ice maker.
8. Using a 1/4” drill bit, drill hole through cabinet from
inside just above the original heat exchanger.
Always use the TORCH GUARD heat shield part
number 5304418872, behind evaporator before
attempting to solder. The excessive heat from
soldering will warp the plastic liner.

Connection
DO NOT cut the cap tube. Cut the line from the
cap tube to the EEV one inch in front of the cap
tube weld.
DO NOT unbraze old filter-drier from system. This
will vaporize and drive moisture from desiccant
back into system. The old filter-drier should be cut
out of system.
15. Allow product to run and make sure refrigerant is
circulating. Reinstall evaporator cover and machine
compartment
cover.
