The reason why the ice machine drops ice slowly:

1, the refrigerant pressure is too high or too low, resulting in the compressor does not work properly. At this time, you should adjust the refrigerant pressure.

2, refrigerant pipeline gas or debris, or pipeline deformation. At this time should check the refrigerant pipeline, for different failures to implement different measures.

3, if the machine is air-cooled type, may be because the fan electrical bad, turn slower so the heat dissipation effect is not good, resulting in slow ice once a long time may burn the compressor. At this time, you should replace the condensing fan in a timely manner, so as not to burn the compressor, resulting in unnecessary losses.

4, insufficient refrigerant (this insufficient is not leaking normal operation or will consume), or too much refrigerant, which will affect the ice-making efficiency of the ice machine. If it is found to be insufficient refrigerant, refrigerant should be added in a timely manner, if it is found to be too much refrigerant, refrigerant should be appropriately reduced.

5, the ambient temperature is too high or too low, will affect the efficiency of its ice, the general ring temperature is best controlled at room temperature 20 ℃, the water temperature of 10 ℃ or so is more appropriate.

6, the ice machine should be installed in a ventilated, easy to dissipate the heat of the location to work, if stuck in a corner, that will seriously affect the various performance of the ice machine.

7, check the filter is not blocked, if the filter element is not replaced for a long time, the ice machine water intake will be very small, which will also lead to the ice machine does not make ice or make ice slowly.

Common Failures of Ice Machines and Solutions

1, the compressor is working, but not refrigeration

Failure: refrigeration fluid leakage or two-way solenoid valve is damaged closed poorly.?

Maintenance: leak detection and repair leakage and then add refrigeration liquid or replace the solenoid valve.

2, the compressor has been working to refrigerate, the pump has been working to pump water, ice continues to thicken, but can not automatically enter the de-icing program to drop the ice

Fault: water temperature probe failure, so that the intelligent control system can not effectively perceive the water temperature and work, misjudging the program error, or controller failure.

Maintenance: use a multimeter to measure the resistance of the water temperature probe, such as resistance in 27K or more, it is judged to be a bad controller should be replaced, such as the resistance is lower than 27K, it is necessary to disconnect any of the two wires, by way of series resistance will be adjusted to 27K to 28K between.

3, the machine into the de-icing program but the ice does not come off

Fault: two-way solenoid valve damage.

Maintenance: replace the solenoid valve body or external coil.

4, the compressor is working but the pump has not been working (no running water)

Fault: water pump damage or water pump internal scale blockage.

Maintenance: clean the pump or replace it.
