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).

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.

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.
