Non-fault phenomenon and common troubleshooting:
★ Non-fault phenomenon:
I heard the sound of water flowing in the refrigerator: this is the sound of the refrigerant flowing.
- I heard the sound of "beeping" from the refrigerator: it was caused by the sudden change of temperature during the opening and closing of the refrigerator, causing the inconsistency of the thermal expansion and contraction of various materials.
- Compressor is hot: When the refrigerator is working, the compressor casing temperature can be up to 90 °C.
- The two sides of the refrigerator are hot: when the refrigerator is working, the average temperature of the cooling condensers on both sides is about 55 °C.
- Fog condensation on the outer surface of the refrigerator: It is formed by the humidity of the air and can be dried.
- Frosting on the back of the refrigerating compartment: Since the refrigerating compartment cooling pipe is close to the back of the refrigerating compartment, the temperature of the refrigerator is lower than 0 °C when it is started, so there will be frost on the back when the refrigerator is running, but the frost will be automated after the shutdown. .
- After the refrigerator door is opened, the LED light does not light up: Check if the power supply of the refrigerator is well powered, and connect the power supply according to the precautions for use.
Common malfunctions:
1, the refrigerator stops working
- The power plug is in good contact with the socket.
- Whether there is a power outage or the home power system is disconnected.
- After the refrigerator is interrupted, the power is turned off after 5 minutes.
2, the compressor has been running continuously
- Is the temperature setting inside the box too low?
- Whether the door is closed or not.
- Whether there is a high temperature heat source nearby or direct sunlight.
- Whether the food is placed too densely, affecting the cold air flow.
- Whether to put overheated food in the freezer.
3. The temperature of the stored food is not ideal.
- Whether the food is placed too densely.
- The refrigerator door is not closed or opened more frequently.
- Is the refrigerator close to the heat source?
- Is the temperature setting inside the box too high?
4, frozen indoor food freeze
- Whether the frozen food is close to the inner wall.
5, loud noise
- The refrigerator packaging base has not been removed.
- Whether the refrigerator is placed smoothly.
- Whether the back of the refrigerator touches the wall.
6, the hand touch the refrigerator has a feeling of hand
- Is the ground wire connected?
- Good grounding but still feeling awkward, please unplug the power cord immediately and contact our after-sales service department.
Note: When the electric device is used for a long time, the surface will be worn or faded, which is purely normal and will not affect the use and will not be replaced.
Note: If your refrigerator is not normal after checking the above methods, please contact our after-sales service department or local authorized maintenance department. Because R600a is a flammable and explosive gas, it cannot be exposed to open flames during maintenance.
Small computer system interface (SCSI) is an independent processor standard for system level interfaces between computers and intelligent devices (hard disks, floppy drives, optical drives, printers, scanners, etc.). SCSI is an intelligent universal interface standard.
SCSI-3
In 1995, the more high-speed SCSI-3, called ultrasci, was born, and the data transmission rate reached 20MB / s. It increases the synchronous transmission clock frequency to 20MB / s and improves the data transmission rate. If 16 bit wide mode is used, the data transmission rate can be increased to 40MB / s. This version of SCSI uses a 68 pin interface, which is mainly used on hard disks. The typical characteristic of SCSI-3 is that the bus frequency is greatly increased and the signal interference is reduced to enhance its stability.
There are many models of SCSI-3. Ultra (FAST-20) has a transmission frequency of 20MHz, a data bandwidth of 8 bits and a transmission rate of 20MBps
Ultra wide has a transmission frequency of 20MHz, a data bandwidth of 16 bits and a transmission rate of 40mbps
The transmission frequency of ultra 2 is 80 MHz, the data bandwidth is 16 bits, and the transmission rate is 80 Mbps
The transmission frequency of ultra 160 is 80 MHz, the data bandwidth is 16 bits, and the transmission rate is 160 Mbps
The transmission frequency of ultra 320 is 80MHz, the data bandwidth is 16 bits, and the transmission rate is 320mbps
The transmission frequency of ultra 640 is 160MHz, the data bandwidth is 16 bits, and the transmission rate is 640mbps
