Why the ice machine does not make ice
1. Poor heat dissipation
The principle of the ice machine and the refrigerator , air conditioning is similar, all heat dissipation problems must be paid attention to when using. The main manifestations of poor heat dissipation are: the ice making time is prolonged or even the ice cannot be made. Due to poor heat dissipation, the compressor is hot and the overheating protection does not make ice. Preliminary treatment Open the cover to observe whether there is dust on the heat sink that affects the wind flow or other foreign objects blocking the heat sink, and it is enough to remove it. In addition, if you use a fan to dissipate heat, see if the fan is running normally. There are also some ice machines that are not cooled by air, but are discharged by pouring water into the condenser, which is called water cooling. This method must check whether the drainage and heat dissipation system is normal, and see if there is water flowing out of the water outlet. Under normal circumstances, adjust the water valve so that just warm water is discharged from the water outlet, which is more water-saving and environmentally friendly.
2. No water supply
Another reason why the ice machine does not make ice – no water supply. Because the water pump is broken and the water cannot be pressed to the ice tray, of course no ice can be made. If conditions permit, the water pump should be cleaned every 2 months. If the water filtration system is not good, it should be cleaned once a month, or the water filtration system should be replaced. Otherwise, the scale will block the pump, or even burn it. The entire ice-making water circulation system should be cleaned regularly, so as not to affect the ice-making effect.
3, Insufficient refrigerant
If you find that the ice machine is taking ice longer than before After eliminating the above problems, it is estimated that the refrigerant in the refrigeration system is insufficient. In this case, it is generally necessary to add refrigerant. If the leakage is serious, there is also a pressure test and leak detection. After repairing the welding, add refrigerant. If the ice machine does not de-icing, it involves the computer board, sensors and other problems.
The reason why the ice maker does not make ice and its inspection
1. The compressor works intermittently
1. The voltage is too low. Check power supply.
2. The contact point is burnt and the contact is not good.
3. System pressure protection.
4. The compressor starter is faulty.
5. The condenser is too dirty, high pressure protection.
2. Decreased ice production
1. The capillary or expansion valve is blocked.
2. The water in the system is too high and there is a slight ice blockage.
3. The condensation system of the ice maker is blocked.
4. The refrigerant is insufficient or leaked.
5. The evaporator is too dirty.
3. Wet ice borneol is not hard
1. The ambient temperature is too high, especially in summer.
2. Add more refrigerant for repaired machines.
3. The water supply of the ice maker water distribution tray is too large.
4. The power of the press is insufficient.
4. The machine runs but no ice is present
1. The water volume of the water pan is not enough or there is no water.
2. The reducer is faulty or the geared motor is faulty.
3. System failure ice blockage, dirty blockage, etc.
4. The ice machine leaks refrigerant and the pressure is not enough.
5. The ice cubes are not thick enough.
5. The ice machine leaks water
1. The water supply of the water inlet valve is too large.
2. The connecting water pipe is damaged.
3. The pipe clamp is faulty.
4. The water level float valve is faulty.
6. Excessive noise
1. The ice maker fan is faulty.
2. The reducer is faulty.
3. The compressor is noisy.
Seven, water shortage alarm
1. The water supply joint filter is blocked.
2. The water supply pipe is blocked.
3. The water inlet valve is blocked.
4. The drain valve is leaking.
5. The water pump is faulty.
8. The system failure is reported when the machine is turned on.
1. The phase sequence problem.
2. The power supply system is faulty.
3. Control board failure
