Measure input voltage(s) before performing this procedure.
Voltage input to
power
supplies must be between the
following range:
VAG
VDC
DE: 85 V min
/132
Vmax
EV:
205V
min
/253
V max.
10.5 to 32 Vdc
A
cAUTION!
Do not short fan wires. Shorting fan wires will
damage the
DC
Power Supply.
1.
Measure voltage across the fan wire harness connector
pins.
II
Refrigerator is operating, fan not running
-voltage
measurement should be negligible.
B Refrigerator is operating, fan running
-voltage
measurement should be between 17 to 22 Vdc.
The
DC Power Supply supplies the fan with 17 to 22 Vdc.
For the fan to turn on the compressor must be running and
the temperature
of
the DC Power Supply must be 95° F
(35° C) or higher.
2.
Test fan operation.
To
test fan, proceed as follows:
a.
Tum
on
refrigerator.
A
cAUTION!
Do
not overheat DC Power Supply! The amount of
heat required to energize the fan circuit
is
minimal.
The fan should come on within seconds.
b.
With
an
air heat gun set
to
Low
Heat and its nozzle no
closer than 4 inches away from DC Power Supply, apply
heat as shown
in
Figure 12. The fan should come on when
the temperature reaches
95° F (35° C). Replace the fan
only when all of the following are present:
1) The temperature around the area indicated
in
Figure 12
is
approximately 95° F (35° C).
2) Voltage across the fan wire harness connector pins is 17
to
22
Vdc.
3) The
fan
does not come on.

CAUTION!
1.
Use low heat setting.
2.
Keep heat gun away from plastic components.
3.
Keep air heat gun at a distance and moving.
\
Heat this area only
to
approximately 95°F (35
oC).
