MR-B46Z-C
(1) Troubleshooting with self-check

This refrigerator has a self-check feature to clarify and indicate where and what the trouble is.

You can perform operation checks and identify malfunction of electric or electronic parts.

Error history is recorded and can be displayed by the refrigerator.

5-2 FLOWCHART OF SELF-CHECK

Self-check

Error history mode (Refer to 5-1.(6)5))
Problem may recover automatically.
Perform the following if error is not displayed
before taking measures or the error which was informed
from user by telephone is not displayed.

Operate the ice-making test.
(Current displayed error: Refer to
in the table below.)
The display of ice making compart-
ment setting will blink during the test.

Self-check

Plug the power cord into outlet.
(Current displayed error:
Refer to in the table below.)

Locate the trouble according to error
display. (See page 24-26)

Is error displayed?

Release the error displayed
mode, and the self-check
is finished.

Release the error display
mode and perform the
self-check again.
(go to )

Yes

Is error displayed?

Was any

displayed during repair?

Yes

During the ice-making
test mode, visually check
the operation of the
ice-maker gear box and the
water pump in refrigerator.

*Wait 10 minutes
before plugging
the cord once
it's unplugged.
(If the cord is
plugged in within
10 minutes, error
may be displayed.)

Unplug the power cord from outlet.

Repair/replace failure part(s)
according to error display.

Self-check is finished.

Set the error display mode.

Reset the error history.

(Refer to 5-1.(6)5))

Perform self-check
procedures through .

Perform error
history mode.

Was the error which was informed

from user by telephone displayed?

And were measures taken?

Perform error
history mode.

Note1: Self-check cannot detect abnormalities in the following parts.

See pages 31-43 for troubleshooting.

Door

switch

Motor

damper

Heater (Water pipe/Vegetable compartment heater, etc.)

Water pump motor

Note2: If any abnormality is found when plugging the power cord,

compressor and fan motor stop for 10 minutes.

Note3: The alarm beeps when some abnormalities (motor-locked) have

occurred at the refrigerator fan motor or the box fan motor.

The alarm beeps every time the door is closed until normal

operation is obtained.

Note4: If any abnormality occurs in compressor's inverter circuit,

the compressor and the refrigerator fan motor stop for 10 minutes

(not only when plugging the power cord).

Self-check and error display method and operation

Release of self-check display mode

Self-check finishes automatically. Error cord display is automatically released 10 minutes later.
