COMPONENT TESTING
Before testing any of the components, perform
the following checks:
• Control failure can be the result of corrosion
on connectors. Therefore, disconnecting
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.
• 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 parts and panels before operating.
Failure to do so can result in death or electrical shock.
BIN THERMISTOR
Refer to page 4-2 for the procedure for access-
ing the bin thermistor.
1. Unplug ice maker or disconnect power.
2. Set the ohmmeter to the appropriate
scale.
3. For the most accurate measurement,
immerse the thermistor in ice water for 5
minutes, then use the 32°F/0°C reading
in the chart.
4. Touch the ohmmeter test leads to the
two bin thermistor connectors. The meter
should indicate as shown in the following
chart.
