Is the refrigerant 12. It feels like overfilling or slightly dirty blockage.

Shenzhen Lier Machinery Equipment **** Sales Department to help: the current is too large, the protection jumps, you adjust the current more.

The sensor is broken, look for Beijing Jiawei.

Obviously, it is protected, you first have to contact the manufacturer, they should have some preset parameters of the standard value, to see if you have made it smaller. Or just let them make it bigger. Nothing is a big deal.

Let me tell you, there is a temperature probe that comes out of the computer board and is given to the evaporator, and this probe fails, and it will be replaced after it is replaced.

It should be caused by the compressor high pressure or low pressure protection, check for system failure.

The ice machine does not go to water, which may be caused by the failure of the water inlet solenoid valve, the failure of the water pump, the blockage of the water pipe, the failure of the machine itself, etc., and the solution of Yuanyuan is as follows

1. Check whether there is water in the pipe, if the waterway of the ice machine is normal and there is water in the pipeline, it is very likely that the water inlet solenoid valve of the ice machine is broken. Maintenance method: If the water inlet solenoid valve is faulty, the water inlet valve cannot be opened, which will lead to the inability to enter the water, and a water inlet solenoid valve can be replaced.

2. If the water pump of the ice machine fails, it will also lead to no water, so check whether the water pump is faulty. Maintenance method: If the pump fails, the pump should be repaired or replaced.

3. Check whether the circulating water pump is working normally. If the pump does not fail, but there is too much limescale in the pipe, there will be a blockage that will cause no water to enter. Maintenance method: If there is too much scale in the water pipe, it is necessary to clean the scale first.

If it is not a problem with the accessories, the reason for not getting water may also be a water pressure problem, and the common situation is that the customer's cooling water is also connected to the filtered water, resulting in insufficient water supply for the water purifier.

Cooling water is only used for cooling, and the water consumption is relatively large, because the tap water flow and water pressure are relatively large, if it is also connected to the filtered water, the cooling water will use up a lot of filtered water, and the filtered water will lead to a lack of **, and then the water pressure can not keep up.

Daily maintenance method of ice machine:

1. The ice machine should be installed in a place far away from the heat source, without direct sunlight and good ventilation, and the ambient temperature should not exceed 35 degrees Celsius, so as to prevent the condenser from dissipating heat poorly due to too high ambient temperature and affecting the ice-making effect. The ground where the ice machine is installed should be solid and flat, and it is necessary for the ice machine to stick to the level, otherwise it will lead to no de-icing and noise during operation.

2. The gap between the back and the left and right sides of the ice-making machine is not less than 30cm, and the top gap is not less than 60cm.

3. The ice machine should use an independent power supply, a special line power supply, and be equipped with a fuse and a leakage maintenance switch, and it should be reliably grounded.

4. The water used by the ice machine should comply with the national drinking water specifications, and a water filtration device should be installed to filter impurities in the water and prevent blocking the water pipe and polluting the sink and ice mold. and affect the ice-making function.

5. When cleaning the ice machine, the power should be turned off, it is forbidden to use the water pipe directly aimed at the fuselage to rinse, use neutral detergent to scrub, and it is forbidden to clean with acidic, alkaline and other corrosive solvents.

6. It is necessary for the ice machine to unscrew the water inlet hose head for two months and clean the water inlet valve filter screen to prevent the sand and mud impurities in the water from blocking the water inlet, which will cause the water inlet to become smaller, resulting in no ice making.

7. It is necessary for the ice machine to clean the dust on the surface of the condenser every two months, and poor condensation and heat dissipation will cause damage to the compressor parts. When cleaning, use a vacuum cleaner or a small imitation curved brush to clean the condensed surface oil and dust, and do not use sharp metal objects to clean to prevent damage to the condenser.

8. The water pipes, sinks, refrigerators and maintenance films of the ice machine should be cleaned every two months.

9. When the ice machine is not in use, it should be cleaned, and the ice mold and the moisture in the box should be dried by using a hair dryer, and placed in a non-corrosive gas and ventilated and dry place to prevent open storage.

Ice machine repair includes the following steps:

1.Check whether the power supply and wires of the ice machine are normal and whether there are any loose or damaged places.

2.Check whether the water pipe of the ice machine and the water pipe of the discharge Qingxiao are normal, and whether there is any blockage or leakage.

3.Check whether the compressor, condenser, evaporator and refrigerant lines of the ice machine are normal, and whether there is any fluorine leakage or other faults.

4.Clean the inside and outside of the ice machine, including the evaporator, condensation delayer, water tank, water pipe, drain pipe and other parts.

5.Replace damaged or aging parts of the ice machine, such as compressors, solenoid valves, sensors, etc.

6.Debug the parameters of the ice machine, such as temperature, pressure, flow rate, etc., to ensure its normal operation.

7.Conduct a performance test of the ice machine to ensure that its ice-making effect meets the requirements.

It should be noted that the ice machine maintenance needs to be carried out by professional technicians, and it should not be disassembled or repaired at will to avoid greater losses.

1.The ice maker won't start.

Possible causes: Power failure: Check whether the power plug and power cord are connected properly.

Fuse blowout: Check if the fuse is blown and replace it if necessary.

Control panel fault: Check whether the control panel is working properly and replace it if necessary.

2.Ice making machine ice is not effective.

Possible causes: Ice formation inside the ice machine: Clean the ice inside the ice machine and keep the ice machine dry.

Insufficient water level of the ice machine water tank: Check whether the water level of the ice machine water tank is sufficient, if you do not dig the chain, you need to add water.

Ice machine condenser failure: Check whether the ice machine condenser is working properly, and replace it if necessary.

3.Ice making machine ice is slow.

Possible causes: Ice machine water temperature is too high: Check if the ice machine water temperature is too high, and reduce the water temperature if necessary.

Ice machine condenser failure: Check whether the ice machine condenser is working properly, and replace it if necessary.

Blocked ice pipeline: Check whether the ice pipeline of the ice machine is blocked, and clean it up if necessary.

4.The ice machine is too noisy.

Possible causes: Ice machine base is unbalanced: Check whether the ice machine base is balanced, adjust if necessary.

Ice machine compressor failure judgment: check whether the ice machine compressor is working normally, if necessary, replace it.

Loose ice pipes of the ice making machine: Check whether the ice pipes of the ice making machine are loose and adjust if necessary.

5.The ice maker is leaking.

Possible causes: Ice machine water tank leakage: Check whether the ice machine water tank is leaking and replace it if necessary.

Ice machine water pipe leakage: Check the ice machine water pipe for leakage and replace it if necessary.

Ice machine seal aging: Check whether the ice machine seal is aging and replace if necessary.

The above are some common problems and solutions for ice machine fault maintenance, if the above methods cannot solve the problem, it is recommended to contact professional ice machine maintenance personnel for maintenance.

Ice machine failure maintenance Daquan pro, hello! 1. The compressor works but does not refrigerate, first check whether the refrigerant of the refrigerator is leaking, if there is a leak, make up the leakage of the refrigerator and then add refrigerant. If it is not leakage, it is the two-way solenoid blind valve of the refrigerator that is damaged and not closed tightly, so replace the solenoid valve.

2. The machine enters the de-icing procedure, but the ice does not fall off, first check whether the two-way solenoid valve of the refrigerator is damaged. If there is damage, the solenoid body or outer coil needs to be replaced. 3. The compressor Cong Sui has been working for refrigeration, the water pump has been working to pump water, and the ice has been thickening, but it cannot automatically enter the de-icing program, you can first use a universal meter to measure the negative value of the probe of water temperature, if the negative value of the probe is above 27k, it can be judged that the controller is broken and the probe needs to be replaced.

If the negative value of the probe is below 27K, either of the two wires needs to be disconnected and the resistance value is adjusted to between 27K and 28K by connecting resistors in series. 4. If the water is lacking, the light is on but the machine does not automatically replenish the water, first check the water inlet of the pipeline, if there is no water, you need to open the waterway and restart the machine. If the inlet solenoid valve is faulty, it is necessary to replace the inlet water seepage solenoid valve immediately.

Hope it helps!

Summary. Hello 1The ice machine compressor works but does not refrigerate.

Cause of failure: refrigerant leakage or damage to the two-way solenoid valve and poor closure. Solution:

Check the cause of the leak first, add refrigerant after repairing the leak, or replace the solenoid valve directly.

Hello 1The ice machine compressor works but does not refrigerate. Reasons for the failure of the wild:

Refrigerant leakage or damage to the two-way solenoid valve and poor closing. Solution: Check the cause of the leak first, add refrigerant after the leak, or directly replace the magnetic valve of the base ridge.

2.The compressor can refrigerate normally, the water pump can operate normally, and the ice continues to thicken, but it does not automatically enter the de-icing procedure.

What's your problem.

What's the matter with the ice machine not de-icing.

Ice cubes are too thin: Ice cubes are too thin, and often the ice cubes come on top of the ice tray before they fall. How to deal with it:

Make a new coil. This method can solve the problem of "too thin ice cubes"; Adjust the ice thickness probe of the ice machine, and if it is a screw adjustment, twist the screw inward to make the ice cube thicker. That is, the farther away the iron sheet of the ice thickness probe is from the ice tray, the thicker the ice cube is, and vice versa, the thinner it is, which can be solved by debugging test.

Ice tray desoldering or ice tray metal and plastic parts on the side are separated: If the ice tray is dewelded on the front of the ice tray, remove the desoldered one directly. If the reverse copper pipe is desoldered, it is recommended to replace the ice tray.

If you can repair the welding striker, you can consider welding. If the metal of the ice tray is cracked separately from the plastic parts on the side, it is necessary to re-apply the silicone to the desensitized crack. The ice tray is too dirty:

If the ice tray is too dirty, pay attention to the use of detergents, and generally clean the ice tray with restraint and acidic liquid. Taking a penny branch can effectively make the ice tray clean, but now a good ice maker will have a one-button cleaning function, so you must pay attention to it when buying. The defrost valve does not open:

If you find that the defrost valve is not open, you must first connect the defrost valve.

Are ice cubes thin? Ice cubes are normal.

Tell us more about the situation.

After the ice is made by the ice-making mechanism, it cannot be de-iced, and if it is not de-iced when it comes to de-icing, it will show that the ice is full after a while.

1. There are foreign substances attached to the surface of the evaporator, which is not conducive to ice making and de-icing, so it is necessary to clean the surface of the evaporator, take the water cooler and the water storage box; 2 Refrigerant leakage; 3. The heating valve is faulty and cannot be opened.

Heating felling in**.

It should be that there is a problem with the scraper.

I'll see if it's a problem with heat logging.

There is no scraper.

It's possible. The heating valve is faulty and cannot be opened. Solution: Replace the heating valve.

Gotta change.
