Before performing diagnostic checks determine which section you will be testing. Convertible drawer
units consist of 2 separate sealed systems with 3 compartments so it is important to identify the correct
diagnostic codes for the compartment you are testing. The upper section is commonly referred to as the
fresh food section even though it may be set for wine. The bottom convertible drawer section is referred to
as the freezer section even though it can be con
fi
gured for fresh food or wine modes of operation. The center
ice drawer will always be operating in freezer mode.
To Enter Diagnostic Mode:
Diagnostic mode can be entered only when in normal mode. Press the zone pad making sure the upper zone
is displayed. Simultaneously press the
lock
and
+
key for 5 seconds. When diagnostic mode is entered, both
digits of the diagnostic code number will be displayed on the customer control, and the option keys will turn
into horizontal lines. Use the
+
keys to increment and the
-
keys to decrement the diagnostic code numbers.
When the code number is displayed, press any other horizontal key to begin that diagnostic system test. The
test mode must be selected within 30 seconds of entering the diagnostic mode or it will time out, normal
refrigerator operation will resume, and the displays will return to the primary control interface state. Once
a test mode is selected, the display will
fl
ash to con
fi
rm the mode selected. When in diagnostic mode,
the interior LEDs will be off unless activated in diagnostics. Initial diagnostic codes (1-14) and extended
diagnostic codes (50-62, 64-71, and 78-86) are accessible in the diagnostic mode. See table below.
To Exit Diagnostic Mode:
At the end of a test session, enter
11
on the display and then press any key other than the
+
or
-
keys to
execute a system restart and exit the test mode. Another option is to unplug the unit and plug it back into
the outlet.
