TEST1:Press the TEST key on the power board to enter the (PULL DOWN MODE), the door display 
panel displays T1 T1 and the refrigerator enters forced refrigeration state: the compressor 
operates normally, the fan runs at high speed, and the defrosting heating wire is disconnected. 
This can be used to test the refrigeration performance.   
TEST2:Press TEST key again in TEST1 MODE to enter the (FORCED DEFROSTING MODE). It will 
act depending on the temperature sensed by the defrosting sensor When the temperature 
sensed by the defrosting sensor is over 10 , the heating wire will exit the (FORCED ℃
DEFROSTING MODE)after 20s’ heating When the temperature sensed by the defrosting 
sensor is below 10 , the heating wire will heat continuously until the temperature sensed by℃  
the sensor reaches 7  In the (FORCED DEFROSTING MODE), the door display panel ℃
displays T2 T2, the refrigerator conducts forced defrosting, the compressor and the fan are 
turned off, and the defrosting heating wire is turned on. At this moment, you can test the power 
of the defrosting heating wire and it should be 153±15W.
