No matter what machine, if it is running continuously for a long time, it is easy to have problems, so you should pay attention to let the machine "rest" when using it in daily work. The cake display cabinet is used every day, and the time will be inevitable. We have to check the handling of small problems. Let's talk about the common fault analysis and processing of the cake display cabinet:

1. The food was frozen just after it was put into the cold room. This may occur because the stored food is licking the cold source on the back wall, or because the scale of the thermostat knob is set too high, causing food to freeze.

2. Is the connection to the power supply good or not connected to the connected plug? These are the most basic problems that lead to non-operation. The emergence of these problems will lead to not working.

3. When the temperature sensor feels hot after a long time of work, there may be problems. In this case, the sensitivity of the temperature controller is very poor, and it is impossible to detect the actual temperature inside the cabinet. And in this case, it is likely to cause frequent startup and shutdown.

4. The protector of the compressor is prone to problems after working for a long time. Although the temperature of the compressor is not very high from the surface, the protector still cannot operate normally after self-protection and power cut. In this case, we must first check whether the temperature inside the cabinet has reached the required temperature, and at the same time should check whether the compressor is faulty.

5. The freezer compartment is not fully frozen. The reason for this may be that the food is stored too much, resulting in storage congestion, cold air flow is not smooth, resulting in an increase in the internal temperature of the cabinet. Or because the ambient temperature is below 10 °C, but the temperature compensated switch is not turned on. It is also possible that the door is not closed, the door seal is deformed or damaged, and the sealing is not strict, resulting in poor external ventilation. The occurrence of these conditions may lead to the problem of insufficient freezing of the freezer compartment.

6. It is necessary to know that when working for a long time, it is likely to delay its downtime, or even stop it or be in a normal working state. If this state is not kept for a long time, this is a normal phenomenon. When the machine is shut down, the temperature inside the cabinet is still Did not reach the required temperature, so it will extend the operating time of the cake cabinet compressor, but if this state is maintained for a long time, then we have to judge whether the refrigerant of the machine compressor is less, if If the inspection is determined to be less, then we must add it in time to ensure that the compressor can work normally.
