1. Measure resistance between the terminals and

check for malfunctioning of a load and wire

connection.

1. R sensor measures resistance of CN30

between ②~⑤.

2. Freezer sensor measures resistance of CN30

between ①~⑤.

3. R-defrost sensor measures resistance of CN30 between ④~⑤.

4. F-defrost sensor measures resistance CN30 between ③~⑤.

5. The measured value above is compared to the sensor specification and the temperature table in

speciication found in the manual.

* Unplug the power cord and disconnect the

connector from the main PCB CN70, 71 and

measure the following:

* Disconnect the connector from the main PCB

CN30.

* Resistance will be lowered while the

temperature rises due to a NTC type sensor.
