Why is the refrigerated display cabinet not refrigerated?

1. First check whether the power line is normal. After turning on the machine, observe whether the red power indicator light of the refrigerator is on. If it is on, it means that the power line is normal. If the power indicator does not light up, find a professional electrician to check the power line. 2. After turning on, the machine will start with a delay of three minutes, and the compressor will start after three minutes. After the compressor is started, the buzzing sound of the compressor will be heard. If the compressor still does not start after three minutes, it means that the compressor is protected by high or low pressure. The power must be cut off to clean the dust on the compressor radiator. After cleaning, turn on the power button of the machine again, delay for three minutes again, find the red reset button on the compressor unit, press the reset button to release, and the compressor will start . 3. Turn on the power, delay three minutes, the compressor starts, but the refrigerator is still not cooling. Observe the pressure gauge of the compressor unit, the normal high pressure is about 15 kg, and the low pressure is about 2 kg. If the low pressure is too low, it is likely that the compressor is leaking fluorine. You need to find a professional master to find the fluorine leakage point and refill the fluorine. 4. The above are the common reasons why the refrigerator is not refrigerating. Commercial refrigerators are non-standard products. Both the machine principle and the use environment are more complicated than household appliances, and such common phenomena are often encountered. If the problem is complicated, you must find a manufacturer for professional after-sales, so the manufacturer's after-sales guarantee is very important. 5. Finally, remind everyone that after a period of use, the radiator will accumulate thick dust, and the compressor radiator of the refrigerator must be cleaned regularly to ensure the heat dissipation effect of the compressor.
