1. No cooling or poor effect
2. The compressor cannot be started
1. When the refrigerator does not refrigerate, we should first check whether the connection of the power supply is normal, check whether the lamp in the refrigerator is normal, and further test with an electric pen.
2. If the power connection is normal, you can monitor whether the compressor is working normally. The compressor emits a small motor vibration sound during normal operation. When the high-pressure output buffer pipe in the compressor is broken, or the screw fixing the pipe is loose, the high-pressure pipe does not exhaust, and the low-pressure pipe does not suction, so the compressor runs but does not cool.
3. When the refrigerator compressor does not start, first check whether the refrigerator power supply is plugged in or whether the refrigerator's power supply is loose, the refrigerator is not well connected to the power supply, of course, the refrigerator compressor can not start.
4. The reason why the refrigerator compressor does not start may also be that the compressor's motor unit is burned, and the problem at this time is that the compressor's fuse is blown, which is a common problem that the compressor does not start.
5. The control machine circuit of the refrigerator fails, and the general phenomenon is that the contact is overheating, burning, wear and tear, etc., which will lead to poor contact of the refrigerator compressor contact.
