Using a 1/2" drill bit, open hole drilled in Step 8 to
1/2" from back of product.
10. Remove stubs of old heat exchanger from
evaporator and install new heat exchanger into
evaporator.
11. Push heat exchanger through hole in cabinet
and set evaporator back in place.
12. Slide Armor-Flex over heat exchanger until cover is
against hole at back of cabinet. The excess cap
tube can be wound around the suction line.
13. Seal the hole on the inside and outside using
permagum.
14. Remove freezer door, baskets and evaporator
cover.
15. Disconnect suction line from pressure regulator.
16. Cut off suction line at freezer liner.
17. Drill a 1/2 inch hole through cabinet next to old
suction line.
18. With the heat shield in place remove the regulator
and place the jumper tube Part# 242036701 over
the line coming from the accumulator.
19. Insert new suction line through liner and connect to
other end of jumper tube and weld in place.
NOTE: You must place the shield behind the jumper
tube when welding.
20. Seal both the top and bottom holes with permagum.
21. The one piece cover can now be installed over heat
exchanger. Place open end of cover with top of
compressor compartment opening. Attach cover to

back of cabinet using screws provided. There is no
need to predrill holes as the screws are self cutting.
22. Replace filter-drier using caution to connect cap
tubes properly as described in the filter-drier
replacement section.
23. Evacuate and recharge system.
24. Bend remaining tubing to fit into machine
compartment opening, being careful not to set up
any excess noise from line vibration.
25. Run product to make sure refrigerant is circulating.
26. Reinstall evaporator and machine compartment
cover.
Freezer Heat Exchanger
Replacement Flex Tray Ice Maker
Models.
Note:
Models with the flex tray ice maker in the food
compartment only have a suction line going to the
copressor from the freezer evaporator. The cap tube
runs from the filter drier to the food compartment ice
maker evaporator inlet. A jumper tube running from the
food compartment Ice maker evaporator to the inlet of
the freezer evaporator.
1.
Recover refrigerant from sealed system.
2.
Disconnect wiring harness at liner plug.
3.
Remove defrost limiter and disconnect defrost
heater.
4.
Remove fan motor and wiring.
5.
Cut suction line off flush with liner (See Figure 7-11
Note:
Models with a flex tray ice maker you do not
need to remove the freezer evaporator since you would
only be replacing the suction line.
6.
Using a 1/4" drill bit, drill hole through cabinet 1 inch
below old suction tube.
7.
Using a 1/2" drill bit, open hole drilled in Step 7 to
1/2" from back of product.
8.
Place a heat shield behind evaporator.
9.
Remove stub of the old suction line from evapora-
tor.
10. Push suction line of heat exchanger through hole
in cabinet and connect to evaporator. Weld line in
place.
11. Slide Armor-Flex over heat exchanger until cover is
against hole at back of cabinet. The cap tube com-
ing out of the armer flex needs to run to the food
compartment ice maker evaporator.
NOTE: For instructions on how to get to the food com-
partment evaporator go to pages 6-26 and 6-28 comp-
nent tear down section.
12. After gaining excess to the ice maker compartment
evaporator (See Figure 7-12) cut the cap tube off
even with the food liner.
13. Using a 1/4" drill bit, drill hole through cabinet 1 inch
above old cap tube and jumper tube..
14. Place a heat shield behind the evaporator and
remove the stub of the old cap tube.
15. Push the new cap tube through the 1/4 inch hole
and place it in the evaporator inlet then weld in
place.
