1, poor heat dissipation
< br >
The principle of the ice maker is similar to that of the refrigerator and air conditioner, and all the heat dissipation problems must be paid attention to when used. The poor heat dissipation is mainly manifested as: the ice making time is prolonged or even unable to make ice. Due to poor heat dissipation, the compressor is hot and overheat protection is not made of ice. Initial treatment Open the boot cover to observe whether the heat sink has dust affecting the wind flow or other foreign matter blocking the heat sink, and remove it. In addition, if you use a fan to dissipate heat, see if the fan is running normally. Some ice makers are not cooled by wind, but by pouring water into the condenser to discharge the heat, called water cooling method. This method must see whether the drainage and heat dissipation system is normal, see whether the water outlet has water flow out, the normal situation is to reduce the water saving valve, so that the water outlet just has warm water discharge, which is more water saving and environmental protection.

2. No water
< br >
Another reason why ice makers don't make ice is because they don't bring water. Because the pump is bad and can not put the water pressure on the ice tray, of course, it can not make ice. If conditions exist, the pump should be cleaned every 2 months, and 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 jam the pump and even burn. The entire ice making water circulation system should be cleaned regularly so as not to affect the ice making effect.

3. Insufficient refrigerant
< br >
If it is found that the ice making time of the ice machine is longer than before, after excluding the above problems, it is estimated that the refrigeration system is insufficient refrigerant. In this case, refrigerant is generally added, and if the leakage is serious, there is pressure test and leak detection, and refrigerant is added after repair welding. If the ice machine does not remove ice, it involves computer boards, sensors and other problems.
High condensing temperature (1) Cooling water (or air) flow is small, high temperature; (2) There is air in the system, which increases the condensing pressure; (3) The amount of refrigerant is too much, and the liquid occupies the effective condensing surface
1, the ice machine service life is too long 2, the machine lacks freon 3, the machine system poor heat dissipation 4, the system blocked 5, the compressor failure of these conditions.
Ice machine compressor is very hot do not make ice solution:
1, due to the long service life of the ice machine compressor, the insulation material in the box, due to thermal expansion and cold contraction and the internal skin of the box slightly separated phenomenon (serious internal box skin has been bulging), the ice machine compressor long-term use of internal parts wear, especially the suction and exhaust valve, the wear will not be too serious, the machine is a little laborious, the insulation effect is not good, etc. It's very natural to get hot. In this case, only a new compressor can be replaced.
2, if the ice machine compressor can start to work, it should be fluorine deficiency. First of all, the ice machine copper pipe has no leakage point, if there is no leak detection and plugging before fluoridation, adding freon will soon leak out. Click to see:
3, the machine away from the heat source area, such as \"no ventilation, the sun, and so on.\" Clean the inside and outside at any time, and clean the condenser dust regularly.
4, shutdown and rectification: before the inspection, ensure that the power is turned off first, check the patency of the ice mouth, any foreign matter should be cleaned up, and check the foreign matter in the water inlet, clean up and then run the machine
5, the compressor can not start, some ice machine compressor above the PTC starter is broken, will lead to the compressor can not start, this time the compressor will be very hot. The sound indicates that the compressor is overloaded (the refrigeration system is blocked) or the compressor is electrically faulty or the mechanical part is stuck. In this case, the compressor is usually replaced.
The machine is aged or the voltage is too high
