Why does Haier refrigerator always call the police? What's the matter? How to solve it?

1) The refrigerator is turned on for the first time or after a long power failure.

2) The refrigerator opens the freezer door for a long time.

3) put a lot of food in the freezer at a time.

4) The air-cooled refrigerator will give an alarm when the refrigerator door is not closed properly or the user opens the door for a long time.

5) The thermostat of the refrigerator is not properly adjusted.

6) It is possible that the program in the display panel is interfered by external electromagnetic interference. As long as it is not frequently alarmed, there should be no problem.

Method:

1, placement location

Pay attention to whether the location of the refrigerator is reasonable and whether it is convenient for the refrigerator to dissipate heat. But also need to check the power supply at home, whether it is grounded or not.

Step 2 read the instructions carefully

Before use, users should carefully read the attached product manual and check all parts of the refrigerator. The power supply used in household refrigerators is mostly 220V and 50Hz single-phase AC power supply. During normal operation, the voltage fluctuation is allowed to be between187-242 V. If the fluctuation is too large, it will affect the normal operation of the compressor and even burn the compressor.

3, electricity safety can not be forgotten.

The refrigerator should use single-phase three hole socket with separate wiring. Pay attention to protect the insulation layer of the power cord, do not weigh the power cord, and do not replace or lengthen the power cord at will.

4. Turn on the machine after standing.

After the inspection is correct, the refrigerator should be allowed to stand still for 2 to 6 hours before starting, so as to avoid oil circuit failure (treated refrigerator). After turning on the power supply, listen carefully to whether the sound of the compressor is normal when starting and running, and whether there is the sound of pipes colliding with each other. If the noise is too large, check whether the product is placed smoothly and whether the pipes are in contact, and make corresponding adjustments. If there is a loud abnormal sound, you should immediately cut off the power supply and contact professional maintenance personnel.

5. Trial operation of the new machine

When starting to use, it is necessary to reduce the load, because the moving parts of the new machine have a running-in process. After running for a period of time, adding a large amount can prolong the life of the refrigerator.

6, the first operation load reduction

When using the refrigerator for the first time, don't store too much food, and leave appropriate space to keep the cold air circulating, and try to avoid the refrigerator working at full capacity for a long time. Hot food should be cooled to room temperature before being put in, so as not to cause the refrigerator not to stop for a long time. Food should be sealed with fresh-keeping bags or paper or put in sealed containers to prevent food from getting wet, losing water and smelling. Foods with water should be put in after removing water, so as to avoid too much frost caused by evaporation of a large amount of water.

repair

No matter whether the system leaks or not, the concentration of isobutane in all areas of ignition electrical devices cannot reach the explosion limit. Because isobutane is heavier than air, it is necessary to ensure that the maintenance site is well ventilated. When pouring refrigerant, in order to avoid the possibility of static electricity and sparks, it is required that all equipment must be reliably grounded, and all wiring must be firm and must not be connected wrong.

A. First, check whether there is a fire source in the surrounding environment and maintain good ventilation;

B. Prepare special equipment and accessories for maintenance;

C. check the safety of maintenance equipment and power supply.
