But he doesn t refrigerate. What s going on, not refrigerating?

1: The press does not start, there is no problem with the temperature setting, but there is no response when the power is on.

If the press does not turn the fan, you must look at the capacitor first.

The capacitor bulge needs to be replaced to eliminate the capacitor and check the power supply.

If there is a power supply machine, overload protection is the key.

If there is no power supply in the house, first check the connecting cables.

Secondly, it is necessary to look at the temperature control, and the temperature control is best replaced.

The relay is a key point, and the front drive should be judged.

If all of the above are normal, the following things will be easy to do.

Motherboard repair or replacement Ask the user to make a decision.

2: Thermal protection for a while when the press is started.

The air conditioner is turned on with cold air, and the temperature then increases.

After a while, the cold air turned into hot air, and the press outside stopped.

At this time, first look at whether the speed of the external fan is low or not.

If the capacitor is low, it is not a capacitor fan.

Secondly, look at the condenser, if it is too dirty, it needs to be cleaned.

Add too much fluorine, and the current will be high, and the press will also stop working.

The capacitance of the compressor should also be seen, and it is best to change it according to the original machine.

3: The press is energized and protected in a few seconds.

Disconnect the power supply line of the press and the external line to judge.

If the power supply is checked normally, on the contrary, replace the capacitor first.

Changed the capacitor and then experimented if it was normal to make money.

On the contrary, turn off the high voltage and turn on the high pressure and then experiment.

If the press is turning normally, the pipe is blocked, which is the key.

If the press does not turn to this point, the press will be replaced.

Note: After the press is protected, the overload protector will not be reset after a while, so if the power is turned on immediately, the press will not respond.

4: The air conditioner will be turned on empty.

When encountering this, don't disconnect the external cable beforehand.

It is good to judge whether it is inside or outside, and it is good to judge and do good work.

The failure of the external unit is easy to deal with the four-way press and fan.

In turn, the line is broken, which is broken, and which is replaced.

Finally, check the connection wire, the mouse gnawed and leaked.

It is difficult to deal with the failure of the internal machine, and the wind swing of the fan is judged first.

Take out the motherboard and take a closer look to see if there is a UMC.

It's really hard to repair the board, and making money is the key.

5: The air conditioner is not refrigerated well or not refrigerated;

This problem is most common and the lack of fluoride in air conditioners is the key.

Turn on the machine first and feel the trachea back by the temperature.

If it is cold, the fan speed may be low.

Inner tube flakes and dust resistant Clean or replace.

If the inner tube is not cool, the thick tube may be flattened.

The return air temperature is not cold, and then touch the air intake to judge.

The air intake is cold and frosty, add fluoride and try again.

If the frost slowly dissipates, it is a good decision to lack fluoride.

It is not difficult to see the aging of the press, and the lack of exhaust is the key.

Four-way gas is also common and is judged by fluoride collection.

High-pressure scales must be seen to be dirty, and they will be slow to refrigerate.

6: The air conditioner does not turn on.

The air conditioner is powered on to experiment by ticking sound.

There is no beep to check the power supply Secondly, look at the motherboard.

If there is a beeping sound, then judge the first step to press the start button.

The air conditioner is easy to start, and the remote control damage is judged first.

Exclude remote control check reception Infrared reception is replaced first.

Check again if there is a power supply signal line.

Then power it up and experiment again to see if the air conditioner turns.

If the air conditioner does not turn, the large block is damaged to this point.

Note: Most air conditioners will have a "beep" sound when they are energized, but there are also some that are not, and this is to judge by yourself.

Cooling, also known as freezing, reduces or maintains the temperature of an object below its natural ambient temperature. There are two ways to achieve refrigeration, one is natural cooling and the other is artificial refrigeration. Natural cooling uses natural ice or deep well water to cool objects, but the cooling capacity (i.e. the amount of heat taken from the cooled object) and the refrigeration temperature that can be achieved are often not sufficient for production needs.

First, the compressor clutch coil was damaged, causing the suction cup Moqing to be unable to engage the belt pulley.

Second, the fuse of the compressor burned out.

Third, it may be that the air conditioning duct is swollen and missing, or it is leaking.

The fourth rental luggage may be due to damage to the pressure sensor on the air conditioning pipe.

If you lack freon, you can add some freon

Generally, it is the problem of fluorine leakage causing freon deficiency and non-refrigeration.

Air conditioning is an indispensable part of modern life, air conditioning cherry blossoms provide people with coolness, but at the same time, air conditioning is often turned on is also easy to cause diseases, such as destroying and burying "air conditioning disease", etc., need to be used with caution.

The reasons for the refrigerator not to refrigerate are: no electricity, the refrigerator is not opened, the refrigerator temperature is set incorrectly, the ambient temperature of the refrigerator is too high, the refrigerator is leaking, the refrigerator is missing, the refrigerator insulation layer is damaged, the refrigerator compressor is faulty, the control line is faulty, the temperature sensor is faulty, etc.

If the refrigerator is not refrigerated, first check the following reasons: Whether the power is connected: check the plug, socket, and insurance, and confirm whether the indicator light is on; Whether the thermostat knob is adjusted to the "0" gear: the 0 gear is not working, and the 7th gear is non-stop; Whether the power supply voltage is too low: The voltage is too low.

Generally, 5-6 gears are played in summer; Play 3-4 gears in winter.

There are generally two types of household refrigerators: direct cooling and intercooling, and direct cooling refers to the heat exchange between the evaporator (cooling pipe) and the freezing and refrigeration rooms to achieve the purpose of cooling; Intercooling means that the evaporator (cooling pipe) is separated from the freezing and refrigeration room, and the cold air is blown into the freezing and refrigeration room by a fan to achieve the purpose of cooling.

Whether your refrigerator is not refrigerated should be judged from the following aspects:

1: Check whether the power connection is normal.

Open the door and observe whether the light in the box is lit, or test it with an electric pen.

2: If the power connection is normal, listen to whether the compressor is working.

The compressor will emit a slight and vibrating motor sound when working normally (if you feel the vibration of the compressor with your hands, then.

Care should be taken not to burn, as the compressor temperature can reach 40-50 in winter and 80-90 in summer

3: If the compressor can work, judge whether the refrigeration system has refrigerant (commonly known as potion).

Let the refrigerator run for a few minutes before unplugging and listen carefully for the sound of liquid running inside the copper tube. If not, it means that the refrigerant in the system has leaked, or the compressor has lost its capacity.

4: If your refrigerator belongs to the intercooled type, you should check whether the fan is working.

Open the door of the freezer compartment and press and hold the button at the edge of the box mouth with your hand (this button controls the indoor lighting and stops the fan from working when the door is opened) to see if the fan is working, as the fan does not work will cause the refrigerator to not refrigerate.

Placing too much food in the box will also affect the refrigeration effect.

There are many reasons why an air conditioner doesn't refrigerate:

1) Fluorine leakage at the connecting pipe joint;

2) There is a leakage point in the connecting pipe;

3) The wiring is incorrect;

4), fuse burning;

5) The compressor is faulty; The starter capacitor is damaged.

6) The external environment temperature is high, and the indoor personnel are more than the United States, and the air conditioner is working at full load.

7) If the power supply voltage is too low, the air conditioner is not easy to start, and it will stop or the fuse will blow after starting, so it is recommended that the user install a power regulator.

8) The air outlet of the air outlet is not large if the temperature does not drop in the strong cold block room, which is the air filter has too much dust, clean the filter.

9) The thermostat is improperly adjusted.

10) The installation position of the air conditioner is not good, which will lead to uneven indoor temperature or poor refrigeration effect, if the above cannot be determined, it will be repaired.

Air conditioning is an indispensable part of modern life, air conditioning provides people with coolness, but at the same time, air conditioning is always on is also easy to cause diseases, such as "air conditioning disease", etc., need to be used with caution.

Air conditioning is an indispensable part of modern life, air conditioning provides people with coolness, but at the same time, air conditioning is always on is also easy to cause diseases, such as "air conditioning disease", etc., need to be used with caution.

There are many cases of non-refrigeration, whether the power supply voltage is normal, whether the refrigeration compressor can operate normally, and whether the temperature is adjusted properly.

The host shows that the driver is of course not refrigerated by the ,,, talent.
