What Should I Do If The Refrigerator Display Cabinet Doesn't Cool Down

If the refrigerator in the display cabinet is not cooling, we can investigate the cause of the malfunction one by one and then carry out repairs:
1. First, use an electric pen or multimeter to check if the power socket has electricity and if the power plug of the refrigerated display cabinet is properly connected. If not, simply turn on the power.
2. If the power is normal, check if the low-temperature switch of the freezer is turned on.
3. If the inspection shows a refrigerant leak, you can replace the refrigerant yourself or wait for a dedicated person to come and repair it. If you want to replace it yourself, you need to open the display cabinet's casing, replace the buffer pipe, identify the leaking part of the system, perform welding repair, pressure testing, and evacuate it. After passing the inspection, add refrigerant to a certain amount.
4. If there is heat at the outlet, it usually indicates that the capillary tube or dryer is blocked and needs to be removed for cleaning. If there is a malfunction, it needs to be repaired.
5. If the compressor is damaged, it is usually impossible to repair it by oneself, and it is necessary to contact the manufacturer or specialized maintenance personnel for on-site repair.
