Secondary Error: R2 sensors, RT sensors, W / T sensors, I / M sensors, I / M Kit. When an error occur the first 3 hours the Primary Error and Secondary Error is indicated in the display check mode (Pressing FREEZER and ICE PLUS button at the same time more than one second). After the 3 hours and if the error is still present the Primary Error will show in the display automatically (See Note 1) and the Secondary Error is indicated in the display check mode. Note1: In the Primary Error after 3 hours of the error occurs all display lights turn OFF except the Freezer Temperature (Trouble Code Index) indicating the failure mode. - 26 -

Primary Error:
F sensor, R1 sensor, D sensor, Defrost errors, F-FAN errors, C-FAN Error.
Secondary Error:
R2 sensors, RT sensors, W / T sensors, I / M sensors, I / M Kit.
When an error occur the first 3 hours the Primary Error and Secondary Error is indicated in the display check mode (Pressing
FREEZER and ICE PLUS button at the same time more than one second). After the 3 hours and if the error is still present the
Primary Error will show in the display automatically (See Note 1) and the Secondary Error is indicated in the display check
mode.
Note1: In the Primary Error after 3 hours of the error occurs all display lights turn OFF except the Freezer Temperature
(Trouble Code Index) indicating the failure mode.
To display the error message, press and hold ICE PLUS button and FREEZER button.
If no errors are displayed, all LEDs
will be illuminated.
If a primary or secondary error is present, certain LEDs will be illuminated indicating failure mode.
