WARNING
Electrical Shock Hazard
Voltage is present during these tests.
CHECKING THE SWITCH PACK
To check voltages at the switch pack:
NOTE: All of the wires must be connected to
the pins on the switch pack to obtain the fol-
lowing readings, including the wire to the pin
being measured. Also, the freezer door light
switch must be in the closed (taped down)
position before performing any voltage checks.
When measuring a voltage, lift the wire con-
nector partially off the switch terminal, and
touch the meter test lead probe to the terminal
(see below).
1.
To check the Light On and Light Off
switches, press the Light button on the ice
and water dispenser front panel, and the
dispenser housing light should turn on. If
the light does not turn on:
a) Check switch pack pins BU/BK and YL/
BK using an AC voltmeter. The meter
should read 115 VAC if the switch is
open, or 0 VAC if the switch is closed.
b) Disconnect the BU/BK and YL/BK wires
from the Light switch terminals. Check
the switch continuity with an ohmme-
ter. The continuity should change when
the Light switch is pressed on and off.
2.
The Locked/Unlocked switch allows AC
voltage to be sent to the motor through the
ice dispenser lever switch when it is in the
Unlocked position. If the Unlocked switch
is defective, the dispenser lever will not
operate the motor. To check the switch:
a) Check pins BU/BK and GY using an AC
voltmeter. The meter should read 115
VAC if the switch is open, (Locked), or
0 VAC if the switch is closed (Un-
locked).
b) Disconnect the BU/BK and GY wires
from the Lock/Unlocked switch termi-
nals. Check the switch continuity with
an ohmmeter. The continuity should
change when the switch is changed
from Locked to Unlocked.
