COMPONENT TESTING
Before testing any of the components, perform
the following checks:
• The most common cause for control failure is
corrosion on connectors. Therefore, discon-
necting and reconnecting wires will be nec-
essary throughout test procedures.
Refer to page 4-18 for the procedure for servic-
ing a thermistor.
1.
Run the diagnostics tests (see page 6-1)
and test the thermistors in steps 01 and
02.
NOTE: For accurate temperature/resistance
readings, continue with the remaining steps to
check the resistance of the thermistor(s).
2.
Unplug the refrigerator or disconnect the
power.
3.
Disconnect the thermistor wire connector
from the main harness.
4.
Set the ohmmeter to the R x 1K scale.
5.
Insert the test probes into the two connec-
tor pins of the thermistor connector.
THERMISTOR
NOTE: If the resistance of the thermistor(s)
was normal, perform the following voltage test.
1.
Set the voltmeter to read a maximum
voltage of 10 volts DC.
2.
Connect power to the refrigerator and
allow it to enter the “cooling” mode.
3.
With the thermistor disconnected and the
refrigerator in the cooling mode, touch the
voltmeter test probes to the thermistor
main harness connector pins. The meter
should indicate approximately 5 volts DC.
If the voltage was not present, check for a
thermistor output at the main control board
(see page 5-5).
6.
Depending on the temperature, the meter
should indicate within the approximate
range, as shown in the chart below.
• Check all connections before replacing com-
ponents, 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 disconnected.
Electrical Shock Hazard
Disconnect power before servicing.
Replace all panels before operating.
Failure to do so can result in death or electrical shock.
