00:00Assalam-o-Alaikum. This is a Greek EE kit. It has an error of L3. This error is due to a fan motor inside the condenser.

00:14A fan is installed to cool the condenser. This is its error. Rest, it has an error when the motor is jammed or burned.

00:25If there is no motor feedback, it gives an error.

00:29Along with this, there is a kit in which it is of Greek. It is the same kit.

00:34In that, you have to see the IPM here. It is installed. This one.

00:40And see, it is written here, IPM 2.

00:44This is IPM 1 and this is IPM 2.

00:46See in this, AC motor will be installed here and L3 error will not come in this.

00:56In this, L3 error comes in the kit in which the DC motor is installed. This is IPM.

01:02You have to remember this.

01:04After this, it has to be checked that what is the reason for this.

01:09The reason for this is that the movies that are made on the usual routine, Mashallah, they say that this jack can not be removed easily.

01:18It will just break, but it will not come out. There is no problem with the jack.

01:21Or there is a problem of cutting the wire of the mouse.

01:25But there is no such problem in this. This has never happened in my service.

01:29Now what happened in this, there is L3 error in this.

01:32When we check it, now we are in front of you and I will clear its L3 error.

01:37And I will show you everything very clearly.

01:41See, just check what is there in it.

01:43See, it has the same UVW in it.

01:47Now in this, it has to be checked that why is the L3 error coming in it.

01:52Let's see this.

01:54See, it has happened that if I put it like this in UVW, it will check the meter.

02:00See, it is giving a buzzer on the meter.

02:03In this, all the points have been shorted.

02:08Now the problem is that in this, just like the feedback capacitors are here, these are also boost capacitors here.

02:20Now its IPM is burnt.

02:23Its IPM is bad because of which L3 error occurs.

02:27Now we will remove the IPM and install a new IPM.

02:31With this, we have this.

02:33I have ordered this new IPM.

02:36We have the money for it.

02:38See, this has IPM in it.

02:41To remove it, a little careful work is done.

02:46See, these pins are UVW pins.

02:49And these are its low side pins.

02:51These are its side feedback pins.

02:54And see, these are double in it.

02:57If even one pin is left, then if we pull it, it will break or get damaged.

03:04It has to be removed and installed properly.

03:07I have a desoldering station.

03:13I remove it from it.

03:15But if someone else removes it in some other way, then it will be a little difficult to remove.

03:22And usually mechanics cut it and remove it.

03:24But as soon as we remove it, let's remove it.

03:28Now we will remove it outside.

03:30I have turned on the desoldering station.

03:33Now it is hot.

03:37After heating, I will remove it.

03:39See, it will hold.

03:42See, now I will remove all the pins.

03:55This is high side.

03:57This is low side.

04:11I have removed all the pins.

04:21Now see, its pins are opened properly.

04:26See, all its pins are opened.

04:33See, this high side is also cleaned.

04:37We did not turn off the camera.

04:39We turned on the camera.

04:41See, this side is also cleaned.

04:45All pins are opened properly.

04:49Give me the tweezer.

04:50I will check it with the tweezer.

04:54I have a doubt on it.

04:55Show it closer.

04:58See, this is also opened.

05:03And this pin is also opened.

05:08All pins are opened.

05:09Now we will remove it.

05:11There is no need to open its heatsink.

05:16Now I will remove it easily from here.

05:19See, it is attached here.

05:23Now I will remove it easily from here.

05:29See, I have removed it slowly.

05:34And see how clean it is.

05:37See, it is 100% clean.

05:39See, it is 100% clean.

05:41And it is opened.

05:43See, it is 100% clean.

05:45There is no such pin that the hole is closed.

05:49Now we will install the new one in it.

05:53And after installing the new one,

05:55we will check it.

05:57If I am not 100% sure,

06:01I can also check this hole here.

06:04See, its hole.

06:06See, it is 100% clean.

06:08This is the low side.

06:09And this is the high side.

06:11See, it is 100% clean.

06:13There is no problem in it.

06:15There is no such thing in it.

06:16See, there is a little bit in it.

06:18I will put it aside.

06:20But this is also the same solution that is applied on it.

06:25But there is no such thing in it.

06:29The video will be a little long.

06:30But it is very beneficial for you to watch it.

06:33You will not find such videos on YouTube.

06:41Now we will install it.

06:43See, its pins are all clean.

06:46See, it has double pins.

06:48Double here and here.

06:50It is a matter of experience to install these.

06:54It is not difficult to install.

06:56Now I will install it.

06:58See, it fits very easily.

07:02See, it fits very easily.

07:08See, it fits on one side.

07:11Now I will do the same on the other side.

07:15See, it fits on the other side too.

07:18See, it fits very well.

07:23Now comes the process of installing it.

07:29See, the process of soldering it.

07:32See, the soldering is done very well from here.

07:40Yes, there is one more thing.

07:41It does not have the problem of fitting.

07:46There is no such problem in it.

07:50The soldering level should be correct.

07:52But it does not happen that how much you will solder it inside and outside.

07:56Now I will install it.

07:59I will show you the whole system in the camera.

08:04See, now I will install it.

08:06First of all, see this is the paste.

08:08You have to use the paste of a good company.

08:11Whatever paste is good, you have to apply it.

08:13Do not apply ordinary paste because it contains carbon.

08:16See, I have done it like this with the help of a brush.

08:19Now I will apply it with the help of a brush.

08:23See, I will apply it with the help of a brush.

08:25You can see it here.

08:27See, I have applied it with the help of a brush.

08:31You have to apply it well on it.

08:35It is applied very well to the bottom.

08:38And now we will do the soldering.

08:41When we do the soldering, you can see it in front of you.

08:43You have to apply it too.

08:44Along with this, we have to apply the high side too.

08:47Do not apply one side and then the other.

08:50You have to apply both sides at the same time.

08:54I am showing you the whole video so that you can do its work.

08:59You have to apply it like this.

09:01You have to apply the base soldering well with the help of a brush.

09:07So that your soldering works well.

09:14So that there is no problem of joint or dry soldering.

09:18Dry soldering is the most dangerous.

09:20The person does not even know what is there in it.

09:22Or there will be an error.

09:24Or there will be some other problem.

09:26See, you can see it from here too.

09:29See, I have done the soldering well.

09:31Now we will do the soldering with the help of a soldering iron.

09:35See, this is a soldering iron.

09:38When you have to apply it, it is important that you clean it well.

09:47See, you have to apply it like this.

09:51You have to apply it like this.

09:54See, it is completely clean.

09:58Now I will do the soldering.

10:01The way to do the soldering is that I have to apply the soldering iron here.

10:06You have to apply it like this.

10:07After applying, when it is completely heated,

10:12until it is completely heated and does not melt,

10:15you do not have to pick it up from here.

10:19See, it should be completely heated like this.

10:25And you have to use the soldering well.

10:37See, the soldering is done.

10:39And you have to do the soldering in such a way

10:42that no one feels that this thing has been repaired again.

10:47Or you feel it is very big only because of its microscope.

10:52Otherwise, when you check it,

10:54you will not feel any such thing in it that how it is now.

10:59See, it is soldered like genuine.

11:02Now we will do all the soldering.

11:06Now our soldering is complete.

11:22We have soldered it completely.

11:25See, it is completely soldered.

11:28This is the low side of the IPM and this is the high side.

11:31Soldering is done.

11:32Now we will fit this kit and run it once.

11:36After running, we will show you that our kit is OK.

11:41See, all the joints are completely soldered.

11:46It is clean.

11:48There is no such problem in it that there is any kind of tension.

11:54See, very good joints.

11:57They are soldered in a genuine way.

11:59There is no such problem in it.

12:03See, all the joints are completely soldered.

12:07Now we will run it.

12:09My purpose of making this video was that

12:12you can put it like this or how you can remove it

12:16or how you can trace its L3 fault.

12:20In this way, you put it and complete it and see

12:24that when it is visible there,

12:27but here I will zoom in and show you.

12:30It is not at all felt that it has any joint or is genuine.

12:35When we clean it well with thinner,

12:39the entire joint of this solder will shine like it.

12:43Now I will show you by communicating and running it completely.

12:52We have done its communication.

12:54Now we will run it only for testing.

12:57See, a compressor is installed.

12:59We will run it only for testing once.

13:02As soon as this motor is turned on, we will turn it off.

13:06After turning it off, I will put its entire heatsink on it

13:10and check you again.

13:12I have started turning it on once.

13:15See, I have turned it on.

13:18And this is its display.

13:20This is its display and this is its remote.

13:22See, I have turned it on.

13:24Now, as soon as its motor will run a little,

13:27I will turn it off.

13:29And after turning it off, we will put the entire system on it

13:31and run it once again.

13:33See, we had put this IPM.

13:35Its motor is turned on.

13:37But we will not run too much because everything is open.

13:40After this, its motor is OK.

13:43Its temperature is 16.

13:45L3 error was in it. L3 error is over.

13:48Now, see, our compressor is also turned on.

13:54Our compressor is also turned on.

13:56Now, we will turn it off along with it

13:58because there is no heatsink in it.

14:00See, our compressor will be heated.

14:03Its motor is absolutely fine.

14:05Now, it is running because the condenser will be cold.

14:08So, it will be turned off.

14:10It has a function.

14:12See, now I have put IPM.

14:14It is absolutely OK.

14:16Now, I will put heatsink.

14:18I will tell you after putting heatsink paste.

14:20I will tell you everything and run it.

14:22Then, I will show you once again.

14:24After this, we will turn it off.

14:27Now, it is the turn of iron.

14:30I will put this.

14:32Let's put this paste.

14:34We have to put this paste in such a way

14:36that only the upper part of it,

14:38this part, where this plate is attached,

14:41only on top of it,

14:43we have to put it very carefully.

14:45We have to put it very carefully.

14:47We have to put it on all components.

14:49We have to put it very carefully.

14:51We have to put it on all components.

14:56This is its bridge.

14:58We have to apply it on top of it.

15:00See, I have put it.

15:02I am putting it quickly so that

15:04there is time left.

15:06These are its two short diodes.

15:10These are its two short diodes.

15:12These are its two short diodes.

15:14We have to put paper on it.

15:16If we don't put paper on it,

15:18it can be tolerated.

15:20But, I put a little bit.

15:22It is better.

15:24Now, we have to put the IPM

15:26that we have changed on it.

15:28We have to put a little bit on it.

15:30We have to put a little bit on it.

15:32But, we don't have to put too much

15:34because if we put too much,

15:36it damages.

15:38It damages the IPM.

15:40It damages the IPM.

15:42We have to put it properly.

15:44There should not be any space.

15:46But, see this.

15:48After this,

15:50we will put the heat sink on it.

15:58Now, when we have put it from here,

16:00I will put its heat sink.

16:02We have to put it from one side.

16:04We have to put a screw.

16:06After putting,

16:08we have to see

16:10whether it fits or not.

16:12Sometimes, it fits or not.

16:14We have to put it from both sides.

16:16Sometimes,

16:18if its legs are little bit up,

16:20we have to put a screw like this.

16:22We have to put a screw like this.

16:24We have to put a screw like this.

16:26We have to put a screw like this.

16:28We have to adjust it.

16:30We have to put a screw like this.

16:34I am telling you this

16:36because

16:38it is not useful to put it.

16:40You may think that it is not useful.

16:42There is no problem.

16:44In this,

16:46we have to put it from one side.

16:48If it is wrong,

16:50sometimes, it cracks the IPM.

16:52From center, side, side.

16:54If there is no crack,

16:56it will be lifted from one side

16:58and it will sit from one side.

17:00Because of this,

17:02its heat does not

17:04spread completely.

17:06And your IPM

17:08will burn due to heat.

17:10See,

17:12I am putting it

17:14little by little

17:16from one side.

17:18I am putting it little by little

17:20from one side.

17:22Later, I will check

17:24whether it fits or not.

17:26If you put it from one side,

17:28it will be lifted from one side

17:30and there will be a gap.

17:32They have not put any adjuster.

17:34You have to tighten the screw

17:36very carefully.

17:38There is no adjuster

17:40in this.

17:42You can see that it is one from both sides.

17:44But you have to tighten it

17:46from one side.

17:48I have tightened it from one side.

17:50And it is pressed

17:52from one side.

17:54So, it has to sit

17:56from one side.

17:58If I would have tightened it,

18:00it would have cracked from the center.

18:02This is a little precaution.

18:04I have told you this.

18:06Don't think that the video will be long.

18:08But you will understand

18:10things very well.

18:12After this,

18:14when I have to put the screw

18:16on top of this,

18:18there is a difference

18:20in the screw of

18:22all the kits.

18:24When I open the kits,

18:26I see that all the kits

18:28have the same type

18:30of screw.

18:32You have to pick up

18:34the wrong screw.

18:36Look at this.

18:38Pay attention to this.

18:40There is a fitting washer

18:42in this.

18:44Zoom it.

18:46There is a fitting washer

18:48in this.

18:50It is a little thick

18:52and in one level.

18:54You have to put the small one

18:56on the short divot.

18:58It will be put on the short divot.

19:00It will be put on the short divot

19:02because the screw on it

19:04is thin.

19:06There is a hole in it.

19:08Don't forget this.

19:10If you put it wrongly,

19:12the small one will break it

19:14or burn it.

19:16Now, let's fit it.

19:18There is no problem in this.

19:20Tighten all the screws

19:22in the same way.

19:26Look at this.

19:28I am tightening all the screws.

19:30Don't overtighten

19:32all the screws

19:34in one go.

19:36Don't over tighten

19:38all the screws.

19:42The video is long.

19:44But look at this.

19:46You have got a lot to learn.

19:48A lot.

19:50If you want,

19:52please like the video.

19:54If you want.

19:56Because you don't like me

19:58by saying.

20:00If you want to subscribe,

20:02please do it.

20:04Because you won't get

20:06this video on any other channel.

20:08Look at this.

20:10We have completed the setup.

20:12Now, look at this.

20:14We have installed

20:16the IPM.

20:18This is the complete kit.

20:20This is the complete kit.

20:22This is the complete kit.

20:24Look at it from one side.

20:26The purpose is to work.

20:28Do it and try to do it well.

20:30But look at the kit.

20:32Don't judge that

20:34this kit has been soldered

20:36or repaired.

20:38Do it like this.

20:40This kit is complete from here.

20:42It is clean.

20:44Look at it.

20:46If you do this,

20:48the ratio of complaint

20:50will be zero.

20:52Now, let's

20:54do the communication.

20:56We have done the communication.

20:58It is complete.

21:00It is complete from all sides.

21:02We have installed the DC motor.

21:04Look at the IPM.

21:06It will start now.

21:08The motor has started to rotate.

21:10The kit is complete.

21:12This is the compressor.

21:14It will start now.

21:16We have shown you

21:18everything without

21:20the camera.

21:22Look at the compressor.

21:24It will start now.

21:26The compressor has started.

21:30Look at it.

21:32The compressor has started.

21:34The kit is complete.

21:36The IPM was

21:38L3 error.

21:40Look at it.

21:42L3 error is ok.

21:44The kit is complete.

21:46The compressor has started

21:48at full RPM.

21:50The compressor has started at full RPM.

21:52We have changed

21:54the IPM.
