1, the refrigerator has just been turned on, and the box temperature has not dropped.

When a large amount of new food has just been put into the freezer.

The temperature control has just been set to a lower temperature. If the refrigerator has an alarm release button (! ) click it and it will be solved.

All of the above are in normal working condition. As long as the freezing room temperature drops, the strobe will automatically go out. If the warning light comes on during normal cooling, there may be several reasons:

1, the freezing room door is not closed tightly and it leaks cold (alarm).

There was a power failure for a long time before this.

3, refrigerator refrigeration failure, it is intuitive that the freezer did not reach the temperature it should reach.

4. The freezing room is cold enough, which is the computer board signal disorder caused by the variable value of the temperature control probe. 3 and 4 can be identified by whether the freezer is normal or not. It is suggested to find us to handle it after sale at 4006999999.

Extended data

1. Blockage of refrigeration system: It often occurs at capillary and dry filter, because these two places are the narrowest places in the system. There are three common reasons for blockage: dirty blockage, ice blockage and welding blockage.

2. Leakage of refrigeration system: the carrier of air conditioning refrigeration and heating is refrigerant. If there is leakage in the system, it means that the air conditioning refrigeration is poor or not at all. The leakage of air conditioning is mainly concentrated in the welding place of two devices, capillary welding, compressor suction and exhaust pipe, bell mouth, copper sodium crack, connecting pipe and so on.

3, four-way valve failure, generally occurs in heating, four-way valve suction is not good, gas channeling or stuck, resulting in poor heating performance, judgment, you can open and close the four-way valve, listen to whether the suction is good, maintenance, you can reset by repeatedly energizing the four-way valve or tapping the four-way valve.

4. The check valve is faulty. When cooling, the check valve is directly connected, and when heating, the refrigerant passes through the auxiliary capillary. When the check valve is not tightly sealed or the auxiliary capillary is blocked, it will affect the heating.
