Degree is less than the second preset time higher than the time of its preset second temperature, and the temperature of the refrigerating chamber presets the 3rd temperature higher than it
The time of degree is less than the 3rd preset time.
10. the control method of refrigerator according to claim 8, it is characterised in that the temperature when in the refrigerating chamber
During less than its default shutoff temperature, also include after the step of control compressor shuts down：
After compressor dwell time reaches the 4th preset time, reacquire in the refrigerating chamber, multifunctional room and refrigerating chamber
Temperature, and the temperature in the refrigerating chamber, multifunctional room and refrigerating chamber and its default switching on and shutting down temperature are compared.
