The air conditioner does not cool well or does not cool.
This problem is the most common, and the lack of fluorine in air conditioners is the key.
Touch the trachea before starting the machine and judge by the temperature.
If the internal machine is cold, the fan speed may be low.
Inner tube scale and dustproof, clean or replace.
If the inner tube is not cold, the thick tube may be crushed.
The return air temperature is not cool, and then touch the intake air to judge.
The inhaled air is cold and cold. Try again with fluoride.
If the frost dissipates slowly, fluoride deficiency must be a good decision.
It is not difficult to see the aging of the press, and insufficient exhaust is the key point.
Four-way gas exchange is also very common and can be judged by fluoride collection.
The high-pressure scale must be seen. Dirt will slow down the cooling speed.
The printing press does not start, and the temperature setting is fine, but there is no response when it is powered on.
If the press does not turn the fan, please check the capacitor first.
The capacitor bump needs to be replaced. If the capacitor is not included, please check the power supply.
If there is power pressure, overload protection is the key.
If there is no power supply, check the connecting cable first.
Secondly, it depends on the temperature control, and it is best to replace the temperature control.
Relay is a key point, and the forerunner should judge.
If all the above are normal, the following things will be easy.
Mainboard maintenance or replacement, ask the user before making a decision.
As soon as the air conditioner is turned on.
In this case, don't mess up in advance and disconnect the external connection line.
It is good to judge whether it is inside or outside, and it is good to judge well.
The fault of the external machine is easy to handle, and the four-way press and fan
Press the handle in turn to break it, and which one is broken.
Finally, check the connecting wire, and the mouse will leak when it bites.
It is difficult to deal with the fault of the internal machine. First, we must judge the fan swing.
Take out the motherboard and carefully check whether there is electricity.
It's really difficult to repair and change boards. Making money is the key.
The printing press is started for a period of time for thermal protection.
Turn on the air conditioner with cold air, and then the temperature rises.
After a while, the cold air turned into hot air, and the printing machine outside just stopped working.
At this time, look at the external fan first to see if the speed is low.
If the capacitor is switched to the low end, it is not a capacitor blower.
Second, look at the condenser. If it is too dirty, it needs cleaning.
If too much fluorine is added and the current is high, the printing machine will stop working.
The capacitance of the press depends on it, so it's better to change it according to the original machine.
The air conditioner doesn't work.
Air-conditioning electrification experiment, according to the beep.
Check that the power supply does not beep, and then look at the motherboard.
If there is a beep, press the start button first.
The air conditioner is easy to start, first of all, it is necessary to judge that the remote control is damaged.
Eliminate the remote control to check the reception, and replace the infrared reception first.
Check the power supply again and repeat the signal loop.
Then power on and experiment again to see if the air conditioner can turn.
The air conditioner doesn't turn, and the big parts are damaged.
Note: Most air conditioners will have a "beep" sound when turned on, but there are some, you can judge for yourself.
After a few seconds of power on, the printing machine will be protected.
Disconnect the power cord of the printing machine, and connect the external circuit for judgment.
If the power check is normal, otherwise replace the capacitor first.
Change the capacitor and try the experiment again. If you make money normally,
On the contrary, turn off the high voltage, and then turn on the high voltage to experiment again.
If the press rotates normally, pipe blockage is the key.
If the press does not turn, replace the press at this time.
Note: After the printing press is protected, the overload protector will not be reset temporarily, so if it is powered on immediately, the printing press will not respond.
