Air Supply Thermistor; Water Valve Solenoid - KitchenAid 2003 M Technical Education

Disconnect power before servicing.
Replace all parts and panels before operating.
Failure to do so can result in death or electrical shock.

AIR SUPPLY THERMISTOR

Refer to page 4-20 for the procedure for servic-
ing the air supply thermistor.
1. Unplug refrigerator or disconnect power.
2. Disconnect the thermistor wire connector
from the main harness.
3. Set the ohmmeter to the R x 1K scale.
4. Insert the ohmmeter test leads into the two
connector pins of the thermistor connec-
tor.
5. Depending on the temperature, the meter
should indicate within the approximate
range, as shown in the chart below.

WATER VALVE SOLENOID

Ice Maker Solenoid
Refer to page 4-28 for the procedure for servic-
ing the water valve.
1. Unplug refrigerator or disconnect power.
2. Disconnect the wire connectors from the
water valve solenoid terminals.
3. Set the ohmmeter to the R x 1 scale.
4. Touch the ohmmeter test leads to the
terminals of the ice maker solenoid. The
meter should indicate approximately 160
to 170 Ω.
5. Touch the ohmmeter test leads to the
terminals of the water dispenser solenoid.
The meter should indicate approximately
330 to 355 Ω.
