4. Disconnect 2 wire leads and remove the
heater.
Note: Evaporator drain probe assists in defrosting
drain. During assembly, probe must be installed
on evaporator and in drain to prevent drain from
freezing closed.
Evaporator (Soldering Method)
1. Recover the refrigerant.
2. Remove the evaporator cover (see Air tower
and Evaporator Cover procedure).
3. Remove the defrost thermostat (see Defrost
Thermostat procedure).
4. Remove the defrost heater (see Defrost
Heater procedure).
5. Disconnect ground wire from evaporator and
position all wiring to allow for evaporator
removal.
6. Remove 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.
7. Desolder the capillary tube from the
evaporator.
8. Desolder the suction line. Use a pair of pliers
to hold the evaporator.
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.
Note: Evaporator drain probe assists in defrosting
drain. During assembly, probe must be installed on
evaporator and in drain to prevent drain from
freezing closed.
14. Install a replacement dryer.
15. Evacuate and recharge the system using
currently accepted procedures.
Evaporator (LOKRING Method)
1. Recover the refrigerant.
2. Remove the evaporator cover (see Air Tower
and Evaporator Cover procedure).
3. Remove the defrost thermostat (see Defrost
Thermostat procedure).
4. Remove the defrost heater (see Defrost
Heater procedure).
5. Disconnect ground wire from evaporator and
position all wiring to allow for evaporator
GEA01164
removal.
6. Loosen 2 screws that hold the evaporator to
the cabinet.
Caution: Tubing must be clean and free from
burrs when using LOKRING.
Note: LOKRING connector P/N WR97X10021
must be used. Two LOKRING connectors are
required.
7. Replace the evaporator using the LOKRING
method (see Pub # 31-9067).
Cut the copper lines of the old evaporator as
close as possible to the aluminum evaporator
tubes.
Cut the copper lines of the new evaporator
1-1/8 in. from the edge of the aluminum
evaporator tubes.
