5-4 Test Function

Test function is to check the product, PCB, process control and maintenance.
After the product function determined by selecting the test switch, you must re-electrify the
appliance to run the self-diagonisis function.
A.Forced Function
1) If you press the Refrigerating Temperature key and the Freeze Temperature key up to 5 minutes
at the same time, the compactor will start running with the display board highlighting FF .
2) If the Forced Function is selected, the compactor will start running without 5 minutes' time delay.
Defrost operation will stop if the appliance is at the state of defrosting.
3) If the forced function is selected, the compactor will keep running for 24 hours. But the
refrigerating temperature may be adjusted by pressing the Refrigerating Temperature key.
B.Forced Defrost
1) If you press the Refrigerating Temperature key and the Freeze Temperature key up to 5 minutes
simutaneously at forced startup state, the compactor will stop running and step into the forced
defrost state with the display board highlighting Fd .
2) If the evaporator sensor's temperature is higher than -5
heater will fail to work and the compactor will resumes after the end of time-delay.
C. Test Quitting
