The reason analysis and solution of refrigeration display cabinet

One. power failure of refrigerated display cabinet：

Refrigerated display cabinets appear without refrigeration we should first check the power supply, then we can open the refrigerator, first take a look at what the indicator is on in the refrigerator freezer, if there are no lights up to check the power plug is loose, if it had no connection of power supply, it certainly can't work.

Repair method: if it is confirmed that the power supply of the refrigerated display cabinet fails during the maintenance, we only need to replug its power supply, so that its failure can be eliminated.

Two. Compressor fault：

If the power supply of the refrigerated display cabinet does not fail, then the second thing we need to check is whether there is any problem with the compressor of the refrigerated display cabinet. If it is refrigerated display cabinet appeared in the summer without refrigeration we will first check whether the fuse refrigerated display cabinet compressor are burn out, the compressor in the process of work without a good heat dissipation and environmental temperature too gao is very easy to cause the compressor to fuse by fusing, eventually led to the refrigerated display cabinet can't normal refrigeration.

Maintenance methods: only a fuse of the refrigerated display cabinet by fusing, would first need to change a new fuse for the compressor, in order to prevent the refrigerated display cabinet after the compressor by fusing again, it needs to be refrigerated display cabinet in a cool ventilated place, refrigerator freezer to ensure the normal heat dissipation, so the temperature of the compressor can be reduced, not again will be blown fuse.

Three. Insufficient refrigerant in refrigerating display cabinet：

The refrigerant in the refrigerating display cabinet is not inexhaustible. When the refrigerant is insufficient, the refrigerating display cabinet will not be refrigerated, which is one of the reasons for the refrigerating display cabinet. When we check whether the refrigerant in the refrigerating display cabinet is really insufficient, we can let the refrigerating display cabinet run for 3-5 minutes, and then cut off the power of the refrigerating display cabinet. At this time, listen to the sound of water flow. If not, it means that the refrigerant in the refrigerating system of the refrigerant in the refrigerating display cabinet has been used up or leaked.

Maintenance methods: refrigerated display cabinet leaked refrigerant if happen the first thing we have to do is find the leak point, through the study of the welding repair of leak parts, pressure testing, etc, the leakage repair, then add refrigerant into the refrigerated display cabinet, usually wait until when add refrigerant evaporator with frost or is the temperature reached the rated temperature shall prevail in the refrigerator freezer, such refrigerated display cabinet is able to refrigeration normal again.

Four. Capillary blockage：

Clogging capillaries in refrigerated display cases can also cause the fridge to fail. When the capillaries in the refrigerated display cabinet are blocked, the refrigerant cannot enter into the evaporator for heat absorption to achieve refrigeration, which ultimately results in the temperature in the refrigerated display cabinet cannot be reduced.

Maintenance method: if the capillary or dryer of the refrigerated display cabinet is blocked, the outlet of them will be hot, then we need to timely clean the refrigerated display cabinet when we carry out maintenance. When encountering the capillary jam of refrigerated display cabinet, we had better ask someone to carry out maintenance, so as to avoid damage to other parts of the refrigerated display cabinet when we maintain it.
