1.Undeserved usage, unsuitable placement, and poor ventilation, too much dust in the condenser and not clean, these can make the condenser cooling, make freezer refrigeration effect. Too much food in the oven, hindered the circulation of air conditioning, can make the temperature in the cabinet is on the high side. Often open the door, compressor boot time is bound to be extended.

2.The power supply voltage is insufficient or plug and socket poor contact both of which may be added to the voltage is lower than the working voltage of the cabinet, and the machine does not start or start frequently.

3.No cream machine during the frost after a sudden power failure or call cabinet is not transported into the frost during the compressor and circuit and frost timer circuit has been cut off, when compressor is up and running, not necessarily but frost timer started to run. Over a period of time, therefore, frost timer running to contact on the compressor circuit, the compressor is natural is up and running. 

4.Different season refrigeration effect is poor, the casing is equipped with compensation heater and energy-saving switch, used to heating in the winter to enclosure, increasing temperature, in order to solve the winter temperature is low, the thermostat is not easy to action make compressor is up and running. If the switch is not closed, winter refrigeration effect variation phenomenon may appear.
