Dryer; Evaporator - GE ZIC36ON Series Technical Service Manual

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 below the evaporator fan and behind
the evaporator cover at the back of the freezer
compartment. An accumulator is attached to the left
side of the evaporator. The accumulator eliminates
woodpecker knock from the sealed system.
To replace the evaporator
1. Recover the refrigerant.
2. Remove the freezer drawer (see procedure).
3. Remove the defrost overtemperature thermostat
and evaporator thermistor.
4. Remove the defrost heater (see procedure).
5. Disconnect the ground wire from the evaporator
and position all wiring to allow for evaporator
removal.
6. Remove the 2 screws that hold the evaporator to
the cabinet.
Caution:
• If desoldering the evaporator, HEAT SHIELD,
P/N WR49X10025, must be used to prevent
damage to freezer liner.
• Protect wiring from heat during
desoldering and resoldering.
• To prevent damage to the capillary tube, the
capillary tube must be desoldered first.
11. Desolder the capillary tube from the evaporator.
12. Desolder the suction line. Use a pair of pliers to
hold the evaporator.
13. Remove the evaporator.
14. 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.
15. Position the new evaporator in the cabinet. Insert
the suction line and capillary tube into the
evaporator.
