You can check your display case as follows:

1, check whether the power connection is normal. Open the door of the box to see if the lighting in the box can be lit, or test it with an electric pen.

2. If the compressor can work, judge whether there is refrigerant (commonly known as liquid medicine) in the refrigeration system. Let the horizontal refrigerator run for a few minutes, and then unplug it. Listen carefully to the sound of liquid activity in the copper tube. If not, it means that the refrigerant in the system has leaked or the compressor has lost its working ability.

3. If the power connection is normal, listen to whether the compressor works. When the compressor works normally, it will make a slight and vibrating motor sound (if you feel the vibration of the compressor with your hands, be careful not to burn it, because the temperature of the compressor is 40-50℃ in winter and 80-90℃ in summer).
