•Test Modes
3.1 Operating Mode
•How to access: Hold down Lock and Freezer Temp buttons for 3 seconds to enter Operating Mode. Once entered, press the
Freeze
r Temp button to change mode selection
0 1 3UI Display
Mode Exit Forced Start Mode Force defrost for FF and Freezer
•How to exit:
Press the Freezer Temp. button until the UI displays the freezer temperature, the hold down the Lock button for 3 seconds
unt
il the Freezer temperature is locked.
Hold down the Freezer temp. and Lock buttons for 3 seconds
3.2 Forced Start Mode
•
The compressor runs for 36h (time-lapse is 10 min.)
•In operating mode, when 1 is selected, the refrigerant exchange valve switches to the FF compartment only. Fresh Food and freezer
compartment fans run at high speed.
•After force starting for 36 hours, the system automatically exits forced start mode and return to previously set temperatures.
3.3 Forced Defrost
•Fresh Food and freezer compartments defrost simultaneously. Forced defrost temperature in the freezer is 17.6°F, while the Fresh
Food is normal defrost temperature.
After forced defrost, normal operation will resume.
•Note: the defrost heaters will be open for at least 2 minutes.
