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.

WARNING

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

EVAPORATOR 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.
