It is said that the compressor is also working when it is de-icing, are you sure that the press will not start? When the press works in general de-icing, the heating valve is opened, the fan pump stops, and the heating valve is closed after the de-icing is completed, and the fan and water pump start to make ice. It is recommended that you make sure that the press does not work when it is de-icing.

There are many reasons why ice machines are slow to make, and here are a few common ones:1The working ring of the ice machine is too high, resulting in poor cooling effect.

The applicable ambient temperature of the ice machine is generally between 18 and 32, if the ambient temperature exceeds this range, it will lead to a decrease in the efficiency of the ice machine. 2.The power supply voltage used by ice machines is unstable.

If the power supply voltage is unstable, the cooling effect of the ice maker will also be affected, and it may not even work properly. 3.The ice inside the ice maker is too thick.

If the ice inside the ice maker is too thick, it will affect the refrigeration effect of the ice machine, resulting in a slower ice making speed. 4.There is not enough refrigerant inside the ice machine.

If the refrigerant inside the ice machine is insufficient, the refrigeration effect of the ice machine will also be affected, resulting in a slower ice making speed. 5.The heat dissipation effect of the ice machine is not good.

If the heat dissipation effect of the ice machine is not good, it will cause the refrigeration effect of the ice machine to deteriorate, which will affect the speed of ice making. In view of the above situation, some measures can be taken separately, such as adjusting the working environment temperature of the ice machine, checking the power supply voltage, cleaning the ice layer inside the ice machine, filling enough refrigerant, cleaning the radiator, etc., to improve the ice making speed of the ice machine.

There can be a variety of reasons why an ice maker suddenly stops during the ice-making process, and here are some of the possible reasons:

1 Temperature sensor failure: There is a temperature sensor inside the ice machine to monitor the internal temperature of the refrigerator, if the sensor fails, the ice maker will misjudge the temperature, causing the ice maker to stop suddenly.

2 Condenser failure: The condenser is one of the key components of the ice machine to remove the heat generated during the ice making process. If the condenser fails, the ice machine will stop making ice because the temperature is too high.

3.Water pump failure: The ice machine needs to send water into the ice machine through the water pump to make ice, if the water pump fails, it will lead to poor water flow, affect the ice making effect, and even make the ice machine stop ice making.

4.Clogged water pipes: If the ice machine water pipe is clogged with dirt or ice cubes, it will affect the flow of water, which will cause the ice machine to stop making ice.

5.Filter blockage: The filter punch ruler inside the ice machine filters the impurities in the water by hand, and if the filter is blocked, it will affect the flow of water and cause the ice machine to stop making ice.

If the ice machine suddenly stops making ice, you can check whether there is a problem in the above aspects first, if you can't solve it yourself, it is best to ask a professional to overhaul and repair.

The reason for the slow speed of the ice making machine is that the refrigerant leakage or the solenoid valve is damaged and the closure is not tight.

Ice making machine ice and de-icing abnormal maintenance, cut off the power supply, restart, first check whether the fan, water pump is working normally, if there is any abnormality to be eliminated first, and then check whether the compressor has started to work, if there is no work should check the part near the compressor, if it has been started, judge the refrigeration system failure, according to the corresponding maintenance method.

If the refrigeration system is fault-free and can make ice normally, but the ice has been made without de-icing, the machine will work abnormally after 90 minutes and will be shut down for protection. The group rules that need to measure the water temperature probe with a multimeter (when the temperature of the underwater tank is close to 0 degrees, unplug the three-core wire in the control box and measure the resistance of the two wires on both sides);

If the resistance is above 27K, it is judged that the controller is bad and should be replaced accordingly, if the resistance value is lower than 27K, it is necessary to disconnect either of the two wires, and adjust the resistance to between 27K and 28K by channeling the resistor.

There are probably several reasons why this may occur:

1.The refrigerant pressure is too high or too low, causing the compressor to work abnormally.

2.There are gases or debris in the refrigerant line, or the line is deformed.

3.If the machine is air-cooled, it may be because the fan appliance is broken and rotates slowly, so the heat dissipation effect is not good, resulting in slow ice making, and once the time is long, it may burn out the compressor.

4.Insufficient refrigerant (this deficiency is not leakage, normal operation or will be consumed); Too much refrigerant, which will affect the ice making efficiency of the ice machine.

5.The ambient temperature is too high The best effect of the ice machine is, of course, the lower the environment, the better the ice-making effect, so when the ambient temperature is too high, it will also affect its ice-making efficiency, and the general ambient temperature is best controlled within 35 degrees Celsius.

6.The working point of the ice machine The ice machine should be placed in a ventilated and easy place to dissipate heat, if it is stuck in the corner, it will seriously affect the various performance of the ice machine.

Hello, I've seen your question, I'm sorting out the answer, please wait a moment.

Question: It takes more than 40 minutes for the ice machine to fall, and there are still a few bars without ice.

If you put the ice machine in a small triangular slit, it will seriously affect the work of the ice machine, which will make the heat unable to dissipate, and if it is serious, the compressor will not work, and it may also lead to no refrigeration.

The questions were very airy.

Answer: If the ice machine is air-cooled, it may be because the fan is broken, which makes it rotate slower, which will cause the machine to dissipate heat well, and if the heat cannot be dissipated, the refrigeration speed will not work, and the speed of ice making will also be slow.

The refrigeration pipe is blocked, and there may be small stones and other debris in it, or the pipe may be extruded and deformed after long-term use.

Questions. No problem with heat dissipation.

If these two reasons are not easy to judge, the maintenance master needs to come to the door for maintenance, because the door-to-door inspection is the most intuitive.

Question R22, kilogram pressure.

That could be a problem with the fan.

It is recommended to move the ice machine to a relatively high temperature environment. Because when the ambient temperature is lower than the applicable temperature range of the machine, the evaporation temperature and condensation temperature both decrease, the superheat of the evaporator increases, and the refrigeration capacity is low, resulting in slow and uneven ice making speed.

It's that the sensor on the refrigeration grid is dirty, just remove it and clean it. If that doesn't work, you can turn the sensor probe up to the appropriate height.

Ice machine in daily use, the machine with a long number of years often does not fall off the ice, analyze and solve this problem:

Reason 1: The ice cubes are too thin, so that the ice cubes will all melt on the ice tray before they fall, and make a new second block.

Solution: Adjust the ice thickness probe, if it is a screw adjustment, twist the screw inward to make the ice thicker. That is, the farther away the iron sheet of the ice thickness probe is from the ice tray, the thicker it is, and vice versa.

Reason 2: The ice tray is too dirty.

Solution: Clean the ice tray. Ice trays are generally cleaned with a gram and acidic liquid.

Reason 3: Ice tray desoldering.

Solution: The front ice grid is desoldered, directly remove the desoldered one, and the reverse copper pipe is desoldered, and the ice tray is replaced. If it can be repaired and welded, you can consider welding.

Reason 4: The metal of the ice tray and the plastic parts on the side are cracked separately.

Solution: Crack the silicone at the crack from the beginning.

Reason 5: The amount of condensate output is too large, and there is still condensate discharged during defrosting.

Solution: Adjust the pressure stop valve to make the water outlet smaller.

Reason 6: The defrost valve does not open.

Solution: The defrost valve is connected to 220V electricity to see if it can be opened, if it can be opened, it is a computer board failure. If it cannot be opened, the defrost valve is faulty, and the defrost valve should be replaced.

There can be a variety of reasons why the ice maker does not drop ice, find out the fault and then fix it.

The time for ice making is too short, or the cooling capacity is not enough. The ice is not completely prepared.

The thickness of the ice can be adjusted inside!
