When in Test Mode, pressing any key once activates manual operation, indicated by 'FF' blinking on the display and a continuous beeping alarm (0.25 seconds ON/0.75 seconds OFF). In this mode, the compressor runs continuously for 24 hours, and Power Freeze/Power Cool functions are temporarily disabled.
Click steps to track your progress.
Understand that 'FF' means the Refrigerator is in manual operation.
To cancel manual operation, turn the appliance OFF then ON again (reset).
Alternatively, select the 'Test cancel mode' described in the manual.
Avoid pressing 'Energy Saver Key + Refrigerator Key' simultaneously for 8 seconds unless intending to enter test mode.
