Sealed System
Filter-Drier Replacement
The filter-drier is located in the compressor area on the
left side of the compressor. (See Figure 7-12)
When the sealed system is opened and the refrigerant
charge is removed, the liquid line filter-drier must be
replaced and the system thoroughly evacuated before
recharging. The service technician must enter the Ice
Maker Service Diagnostic Test 49C and toggle the EEV
(Electronic Expansion Valve) to ON prior to flushing or
evacuating the sealed system.
The refrigerated ice maker in the food compartment of
a French Door Bottom Freezer Refrigerator requires a
second cap tube that must be installed in the filter-drier.
This required a kit to be set up containing a Tee to
connect the second cap tube. There are two replacement
kits available. The part number for the Dye Drier Kit is
5304473019 (See Figure 7-13). The part number for the
Two Stage Drier Kit is 5304473020 (See Figure 7-14).
The non-dispenser models use a simple design filter
drier with the process tube coming off the bottom and the
cap tube soldered into a hole in the process tube.
(See figure 7-15)
On R-134a systems, the system must NOT be left
open to the atmosphere for more than 10 minutes
to prevent moisture contamination of compressor
oil.
To remove the filter-drier:
1. Pull unit from its installation position and unplug
from wall outlet.
2. Extract the screws securing the compressor shield
to the unit frame and remove from unit. Drop
compressor area mounting tray if needed.
3. Attach an approved self tapping line tap valve to the
process tube. Connect refrigerant recovery system
to tap valve. Turn on recovery system, open the
line tap valve, and allow refrigerant to flow into an
approved tank. The service technician must enter
the Ice Maker Service Diagnostic Test 49C and
toggle the EEV (Electronic Expansion Valve) to ON
prior to flushing or evacuating the sealed system.
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.
