Dryer

The dryer is positioned vertically in the center of the
machine compartment. A copper process tube,
connected to the inlet of the dryer, provides access
to the high-pressure side of the refrigeration
system. The capillary is connected to the outlet of
the dryer. Replacement of filter dryer requires
additional refrigerant when installed (0.5 oz).

Evaporator

The evaporator is made of copper and aluminum
and is located above the evaporator fan at the top of
the freezer compartment.
To replace the evaporator
1. Recover the refrigerant.
2. Remove the evaporator fan (see procedure).
3. Remove the defrost heater (see procedure).
4. Remove the defrost overtemperature
thermodisk and evaporator thermistor.
5. Disconnect the ground wire from the evaporator
and position all wiring to allow for evaporator
removal.
6. Remove the screws securing the evaporator to
the cabinet.
Caution: Protect wiring from heat during
desoldering and resoldering.
7. Desolder the capillary tube from the evaporator.
8. Desolder the suction line.
9. Remove the evaporator.
10. Using a file, score the capillary tube just above the
old solder and break the solder-covered section
off. This will help prevent the capillary tube from
becoming plugged when resoldering.
11. Position the new evaporator in the cabinet.
Insert the suction line and capillary tube into the
evaporator.
12. Solder the suction line to the evaporator using
silfos.
13. Solder the capillary tube to the evaporator using
silfos.
14. Install a replacement dryer.
15. Evacuate and recharge the system using
currently accepted procedures.
