00:00As-Salaam-Alaikum. This is a Greek Gate. The problem with this is that when the voltage is given, the compressor turns on and does not catch the speed.
00:15After a few seconds, the compressor turns off and there is no error in it. Now I will turn it on.
00:24I will tell you what is the problem with it and how to repair it.
00:33See, the motor is running. It is running very fast. The outdoor motor is on.
00:38With this, we have kept an analyzer. When the voltage comes to the compressor, 6 of the 6 IGBTs are working fine.
00:48But it turns off immediately. You can see the compressor moving.
00:54You can also hear the sound of the compressor on the analyzer.
00:57See, 6 of the 6 are on.
01:00And 6 of the 6 IGBTs are also on.
01:03This is how much it runs. It turns off.
01:05The outdoor motor keeps running and so does the indoor motor.
01:08Now I will check the problem. What is the problem with it? Why is it coming? What can be the problem with it?
01:15See, I turned it off.
01:17Now after some time, the outdoor motor and the indoor motor will turn off.
01:21See, I have turned it off with the remote.
01:23It is off.
01:24Now after it turns off, I will see what is the problem with it. You need everything.
01:30See, both the motors are off.
01:33Now I have removed the voltage of the kit. It is completely off.
01:38See, the display is also off.
01:40Now I will check it and tell you what is the problem with it.
01:43Why is the problem with it?
01:46This is our IPM.
01:49First of all, you should know what the pin number is and how you have to check the pin.
01:57See, these are the pins.
02:00This pin, this one, it has a lot of diagrams.
02:06For example, A1, B1, A, A, A, A, A, B, A, etc.
02:13The purpose is that these two pins will be counted in one.
02:17After this, it is 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15.
02:30Like this, you have completed these pins.
02:32These are the pins.
02:34After this, what you have to do is that you should know the numbering of this pin.
02:40And you should know what is the use of it and what voltage comes in it.
02:45For this, I will put the meter here.
02:50You can see that two numbers have started here.
02:54This is 2, this is 3, this is 4, this is 5.
02:58It has 5 numbers from here.
03:02This is 5, 5, 6 and 7 numbers.
03:06On this, a pulse will come to the gate.
03:09As you made my video before, there are 6 IGBTs in it.
03:13When this microprocessor gives a pulse to turn it on,
03:202, 2.5 volts, 2 volts, 2.5 volts, 3 volts will come here.
03:27But don't try to check it with a meter, check it with a DSO.
03:32If you check it with a DSO, it is better because it has a logic pulse.
03:42When the logic pulse comes in it, you have to check it.
03:47I will tell you all the pin numbers.
03:50See this, 5, 6, 7 numbers.
03:53It will be clear up to 7 numbers.
03:57It will come in 8.
03:59It has 15 volts on 8.
04:01There are 9 numbers, ground, non-metered.
04:05It is from inside, but sometimes from outside.
04:07The joint below it is also non-metered.
04:11After that, 10, 11, and 12 numbers will come on its logic pulse.
04:18You can check it better with a DSO.
04:23After that, we come here.
04:25This end pin is always for its temperature.
04:30There is a sensor inside it, like your normal sensor.
04:34You keep it like this, keep it at 20K.
04:37If I keep it here and check it, I will get a reading of 4K.
04:45If I keep it hot, the reading will be less and more.
04:49After that, when it cools down.
04:51After that, we come from here.
04:54It is so clear from here, it comes from here.
04:57This is the pin on this side.
04:59This is the ground of the temperature sensor.
05:03After that, we have only two pins left.
05:06This is the fault out pin.
05:08Our voltage comes on this pin.
05:11It will come to the point where our microprocessor will work.
05:16Its pin will work at 3.3 volts.
05:19So here we should get 3.3 volts on this pin.
05:23And after that, the next pin is pin 8.
05:26Pin 8 and pin 13, both are VCC.
05:29It has 15 volts and all of you get voltage on it.
05:34This is the way to check it.
05:37Now we will see what is the problem with it and why it is happening like this.
05:48One of the main things to see is that it is closed.
05:55What is the problem in it, what is it, what is not there.
05:59We will do this.
06:01Let's see if it happens or not.
06:03What is the problem with it, if we get a fault.
06:06Look at this.
06:11Look at this.
06:12It has a license of 330 ohms.
06:16Its number is 331.
06:18I am checking all of this.
06:20You will have to check it with 6 of 6 licenses.
06:23You are getting 329.
06:25This is fine.
06:26Now we will check this.
06:29This is also 330.
06:31This is also 330.
06:34This is also fine.
06:35This is also 330.
06:37And this is also fine.
06:39This means that 6 of 6 IGBTs are being turned on.
06:44There is no dot in it that any device is broken.
06:48I have checked it carefully.
06:50This is fine.
06:51Now in this, there is one more thing to see.
06:55Which pin of the microprocessor is coming from here to here.
07:03We will check that.
07:04If those pins are fine.
07:06Then we will see what is the problem in it.
07:12Look at this.
07:14I have put it on its pin.
07:16The first logic comes in it.
07:18Voltage, logic, voltage comes in it.
07:19Sorry, logic, pulse comes in it.
07:21I have put it on first.
07:23Now this is our microprocessor.
07:26Look at its pin number.
07:271
07:28Look at this.
07:29You have to count like this.
07:30After counting, look at this.
07:32Its pin number will be 9.
07:331
07:342
07:353
07:364
07:375
07:386
07:397
07:408
07:41This is 9.
07:43Look at this.
07:44Show it on pin number 9.
07:52This is on pin number 9.
07:53This means that it is connected directly from here.
07:57Now the problem is that in this.
08:02The problem is that you have to check all its pins like this.
08:056 pins are directly connected to it.
08:09If this is correct.
08:10If this is correct.
08:11It means that in this fault.
08:14This microprocessor is broken.
08:17If this is correct, then this microprocessor is broken.
08:21You have to check this.
08:22Capacitors are connected to it.
08:23These are small.
08:24You can see these.
08:25I will show you.
08:27These are the capacitors.
08:28These are SMD capacitors.
08:31You have to check this.
08:32If this is also correct.
08:34Then it is a sure thing that its microprocessor.
08:38It is broken from inside.
08:39There is no point in working on it or doing anything on it.
08:43And even if your voltage does not come.
08:46This fault can come.
08:47When you have to check the voltage.
08:49There is no problem.
08:50Put it directly like this.
08:52I will put it in series.
08:53I will check its voltage.
08:55I will show you by passing it here.
08:58How will the voltage be checked here?
09:01And I will put this meter at 20 volts.
09:03I have done this.
09:04I think the meter will be visible properly here.
09:07Okay.
09:08Look at this.
09:09Here I will put it in series.
09:10I will not put it directly.
09:11Look at this.
09:12By putting it in series.
09:13It will have to be checked very carefully.
09:15It should not be that your wire is connected from somewhere.
