Evaporator (Brazing Method)
Caution
:
•
If unbrazing the evaporator, HEAT SHIELD P/N
WR49X10025 must be used to prevent damage
to freezer liner.
•
Add thermal paste (WX5X8927) to the exposed
Liner or any item that heat from a torch may
come in contact with.
• Protect wiring from heat during unbrazing
and re-brazing.
12.
Cut the suction line off of the evaporator (see
image below).
13.
Cut the capillary tube section off (see image
below).
14. Unbraze the capillary tube.
15. Unbraze the suction line.
16. Remove the evaporator.
17.
Using a file, or cap tube cutter (WX05X10050)

braze and break the braze-covered section
off. This will help prevent the capillary tube
from becoming plugged when re-brazing.

Insert the suction line and the capillary tube
into the evaporator.
