Before testing any of the components, perform
the following checks:
•
The most common cause for control failure
is corrosion on connectors. Therefore, dis-
connecting and reconnecting wires will be
necessary throughout test procedures.
•
All tests/checks should be made with a
VOM or DVM having a sensitivity of 20,000
ohms-per-volt DC, or greater.
Disconnect power before servicing.
Replace all parts and panels before operating.
Failure to do so can result in death or electrical shock.

•
Check all connections before replacing
components, looking for broken or loose
wires, failed terminals, or wires not pressed
into connectors far enough.
•
Resistance checks must be made with
power cord unplugged from outlet, and
with wiring harness or connectors discon-
nected.
WARNING
Electrical Shock Hazard
2.
Disconnect the wire connector from the
component under test.
3.
Set the ohmmeter to the R x 1 scale.
4.
Water Inlet / Dispenser Solenoids: Touch
the ohmmeter test leads to each of the
water inlet/dispenser valve solenoid termi-
nals. The meter should indicate between
700 and 900 Ω. If the reading is outside
this range, replace the valve assembly.
5.
Thermistor: Touch the ohmmeter test
leads to the thermistor terminals. The
meter should indicate as shown in the
following chart.
