00:00Assalamualaikum, this is a DOLLARS kit and it has an error of P4.
00:08When the kit is running and the compressor is running, the compressor is turned on.
00:13After a few seconds of running, the compressor is turned off.
00:18After turning it off, there is no error on the display.
00:22But what happens is that the error is displayed on the P4 display.
00:31This kit is available in DOLLARS, PAL and a few other models.
00:37Now let's check why this kit has an error.
00:42This device is used to check whether the IPM is correct or not.
00:54This is the model number of this company.
01:03These are the communication lights.
01:10You can see these two lights.
01:14These lights are for communication.
01:18These lights are for the 6 IGBTs.
01:24If the IGBT does not work, then there is another problem.
01:28If the IGBT is working, then there is another problem.
01:31To check this, we need this important thing.
01:34If the IGBT is working in the compressor, then we know what the problem is.
01:44Let me show you how it works.
01:47First, let me turn on the IGBT.
01:55Now I will turn on the IGBT with the remote.
01:59I have turned off the light so that you can see the IGBT.
02:08As soon as I turn on the IGBT, the IGBT will turn on automatically.
02:15Let me show you how it works.
02:17As soon as I turn on the IGBT, the IGBT will turn on automatically.
02:25At the same time, the compressor will stop working.
02:28This light has given us an error of P4.
02:35Now we will repair this light.
02:38Let's see why we have an error of P4.
02:44I will turn off the IGBT.
02:47After turning off the IGBT, we have completely disconnected it.
02:50Now we will work with the camera off.
02:53Because we have to work a little fast.
02:56The video will also be a little short.
02:58I will tell you what was the fault in this.
03:03I will show you again.
03:13I have turned on the IGBT.
03:18As soon as I turn on the IGBT, the IGBT will turn off automatically.
03:31Now we have to see what was the fault in this.
03:39I will tell you later.
03:43I will show you again.
03:53I have checked all the kits.
03:56I have checked all the SMD kits.
04:00There is one more problem in this.
04:03I have started sharing a very useful thing with you.
04:07You have to watch a very useful video.
04:11No matter what my video is.
04:13I don't say that you are thinking with me.
04:15There is no benefit for me.
04:17Your benefit is to watch my video completely.
04:19So that the way I make a video.
04:21No one makes a video like this.
04:22Nor will anyone tell you this.
04:24See this.
04:26I am showing you in the camera.
04:29I have checked all the SMD kits in this series.
04:34See this.
04:36There is an IC here.
04:38The reason for this problem is all right.
04:42Now the problem is that all the kits in this.
04:47I will give you a lot of information in this movie.
04:50A lot.
04:52And one brother asked me.
04:54You have kept so many meters.
04:57Why have you kept this?
04:59This will work with one meter.
05:01It is kept because this happens to us.
05:05Today I will also tell you.
05:07What is the benefit of these meters?
05:09What is the benefit of this meter?
05:11What is the benefit of this?
05:12What is the benefit of this?
05:13And all these meters.
05:14What is the difference between them?
05:15And what do they do?
05:17I have kept all these things.
05:20I have not kept it for no reason.
05:22I have kept it for a purpose.
05:24Today I will give you a view of 2-3 meters.
05:27What does this meter do?
05:28What is the difference between them?
05:29You will check it yourself.
05:31The video will be long.
05:32But it is necessary to see.
05:33I am making it for your benefit.
05:35I have no benefit in this.
05:36I am making this video for your benefit.
05:38This is a very useful video.
05:40I am making this video for the benefit of those who work.
05:44See this.
05:45This is a meter.
05:46I have better quality meters than this.
05:48Okay.
05:49People keep this meter there.
05:50They also keep this.
05:51But this meter is a little good.
05:54Due to this, the ratio of the damage of the kit is more or less.
06:02The mechanic who works on the second number,
06:05his work is faster.
06:07Today we will see in this.
06:09Whatever I am telling you is right or wrong.
06:12See this.
06:13You decide for yourself.
06:15See this.
06:16I am checking with this common meter.
06:19When this resistance comes in front of you,
06:21This is the resistance.
06:23I have taken the value of this in one way.
06:25See this.
06:26This is my black probe.
06:27Okay.
06:28This black probe is here.
06:29Now I will change it.
06:30See this.
06:32If I change it like this,
06:34It will tell us.
06:35It is almost common.
06:37The mechanic will say that this SMD is fine.
06:40There is no problem with this.
06:42This is the reference resistance.
06:44I will tell you everything else with it.
06:47See this.
06:48Our SMD is OK according to this meter.
06:51Now I will change the second meter.
06:55Now I have put the second meter.
06:57This meter is fine.
06:58You can see the second meter.
06:59Now I will check with this.
07:01Okay.
07:02First of all,
07:03I will put the negative probe here and the positive probe here.
07:05Okay.
07:06See this.
07:07It has given reading in this.
07:09It is 1K.
07:10See this.
07:11How much reading has come?
07:12How much reading has come in 1700?
07:13Okay.
07:14And if I put it this way,
07:15See this.
07:16And if I put it on the other side,
07:18See this.
07:19How much reading has come in this?
07:21Now this meter has told us that our SMD is bad.
07:26And it will be repaired.
07:28I will tell you later what the problem is.
07:32See this.
07:33Now I have started checking this SMD on this meter.
07:37Okay.
07:38When this is checked,
07:39See this.
07:40Now what does it have to tell us?
07:42This is in the key.
07:43See this.
07:44I am putting it here.
07:45See this.
07:46You can see.
07:47This meter is telling us that your SMD is bad.
07:52You should not use it.
07:55It is not telling us about SMD.
07:58It is telling us about IC.
08:00That our IC is bad.
08:04See this.
08:05You can see.
08:06See this.
08:07I have touched it.
08:08Okay.
08:09See this.
08:11Okay.
08:14I think you must have understood
08:17What is the benefit of these meters?
08:20Which are good instruments?
08:22How can you repair things in a good way?
08:26See this.
08:27It did not show any reading.
08:28It just told us that our SMD is bad.
08:34This is called Reference Resistance.
08:37So, this kit is available with every IC.
08:41The purpose of this kit is that when the kit is switched on and the compressor is running,
08:49it has to provide a proper voltage.
08:52This is now damaged.
08:55Actually, the resistance is not damaged.
08:58This microprocessor is damaged.
09:03There is a problem with this microprocessor.
09:06This kit cannot be repaired.
09:09If we had used a normal instrument, a normal meter,
09:12no matter how long it would have taken,
09:15we would have changed the SMD.
09:18We would have changed the SMD of the entire kit.
09:22We would have done everything.
09:24But this kit would not have worked.
09:27I will tell you in the next video how I checked the low side of this kit.
09:32I have also checked this.
09:34This was in front of you.
09:36I have told you this.
09:38Now, I will tell you what other things are there in this kit.
09:45I will mention that too.
09:48So that you can work whenever you want in this video.
09:53I am going to tell you a very useful thing today.
09:56If you look at all the kits, you will find the same.
10:00This kit is the same.
10:02That's why I am telling you this today.
10:05I often get a call from someone.
10:08Look at this.
10:09This is your kit.
10:11I tell them to check this SMD.
10:13They say that SMD is also correct in this.
10:15And I also say that it is correct.
10:17But look at this SMD.
10:19This is the same kit.
10:21But look at this.
10:23Here is R172.
10:25There is R187 in it.
10:27There is a lot of difference in the kit.
10:29If you look at the reference, there is more resistance in it.
10:35The resistance in this is more.
10:38100 ohms.
10:40In this way, in different places, in different kits, the kits are the same, but there is a difference.
10:46Look at this.
10:48I have another kit.
10:50Which came for 100 rupees.
10:52But I am showing you this so that you can do it.
10:54Look at this.
10:56This is the same kit.
10:58Whenever I put it like this, look at this.
11:00Its reading has been shown by the entire meter.
11:02And even if I put it on the other side, it will still show the whole thing.
11:06The problem with this is that look at this.
11:09Okay.
11:10This is the whole reading.
11:11Now the purpose is that this is a microprocessor, which is bad.
11:17Okay.
11:18And I have another kit with us.
11:21Just to show you that you know.
11:24You see.
11:26If you like my video, if you have understood anything, if you have liked anything in it, then like it and share it.
11:33I have given you very useful information.
11:36But subscribe to our channel and get people to do it.
11:39Get your brother mechanics to do it.
11:41If any brother wants to learn work, then he can contact us.
11:46Goodbye.
