00:00Assalam-o-Alaikum
00:02This is the error of Hc of GRI
00:04This is the kit for repairing
00:06Let's check why Hc error occurs
00:10This error does not occur immediately
00:12You will turn on the kit
00:14When the compressor is to be turned on
00:16This Hc error occurs
00:20First of all, to check the error of Hc
00:24Check the main thing of the kit
00:26That its communication is going on
00:28The main fault was to be repaired
00:32This is the error of E6
00:34This is the error of E6
00:36We have cleared the error of E6
00:38Now the error of Hc occurs
00:42When the error of Hc occurs
00:44We have to check one or two things
00:46I will show you
00:48After turning off the kit
00:50This kit should be collected or alone
00:52Let's check the cold of the kit
00:54We will show you by measuring
00:56What are those things
00:58We took off the kit
01:00After disconnecting the kit
01:02The first thing you have to do
01:04The compressor
01:06These are charged
01:08It is dangerous
01:10It is dangerous
01:12Whenever you work on the kit
01:14You have to do it
01:16Whenever you work on the kit
01:18First of all, you have to
01:20See this, it is discharged
01:22Now
01:24First of all, we will give separate current to it.
01:28See, I am giving separate current to it.
01:30The purpose of giving separate current to it is,
01:32that you can remove its sensor,
01:36this is its fuse, remove this too.
01:38And this is its compressor.
01:40I have removed this too.
01:42Now, everything will be clear.
01:47First of all, check its PFC problem.
01:50First of all, we will give voltage to it.
01:52Because, this reactor is installed inside it.
01:56It won't be installed from outside.
01:58Now, we will give voltage to it.
02:00See, I am giving voltage to it at L.
02:02And I am giving voltage to it at N.
02:04Whenever you want to check the circuit,
02:06you have to check it on series lamp.
02:08You don't have to direct it.
02:10I have installed a 200W bulb on series.
02:14Now, we will check it.
02:16First of all, I will check its cool.
02:18I will check it with meter.
02:20See, if there is any problem.
02:22First of all, I will put the meter on buzzer.
02:24I will put it later.
02:26First of all, we will check its reactor.
02:30See, there are two types of windings in it.
02:32One is the arm reactor.
02:36See, the arm reactor is like this.
02:40There is only one winding in it.
02:42It winds like this.
02:44The other one comes out from here.
02:46If I want to check this,
02:48See, the movie is made.
02:50It is checked with LCR meter.
02:52See, it is fine.
02:54They have installed a system in it.
02:56If there is more load on it.
02:58There is a thick wire in it.
03:00And there is a brake wire in it.
03:02Its function is that,
03:04if there is more load in it,
03:06then it will give protection and close it.
03:08Or to turn on PFC etc.
03:10See, here is double.
03:12I have made a movie of it.
03:14You can see it with full detail.
03:16First of all, I will check
03:18whether our beam comes here or not.
03:20Because of this,
03:22PFC error occurs in it.
03:26Let's check it from here.
03:28From here.
03:32See, this is its brake winding.
03:34It is fine.
03:36Sometimes it gets disconnected.
03:38Because of this,
03:40our HC error starts to occur.
03:42This is fine.
03:44Now, we will check
03:46its IGBT.
03:48We can check its short diode
03:50and IGBT.
03:52We can check its fault.
03:54We can check it in diode mode.
03:56You can see,
03:58I have made a movie of everything.
04:00You can see it with full detail.
04:02You can check it with full detail.
04:04This is fine.
04:06This is also fine.
04:08After this, we check this.
04:10This is also fine.
04:12This is also fine.
04:14This is also fine.
04:16This is also fine.
04:18Now, our reactor is also fine.
04:20You can check this also.
04:22I will put it here.
04:24Our reactor is also fine.
04:26We have checked both the coils.
04:28Everything is fine.
04:30Now, we are left with this capacitor.
04:32This big one.
04:34It is better to check it
04:36after removing it from capacitor testing.
04:38Otherwise, we estimate it here.
04:42This long beep is coming
04:44because capacitor is big.
04:46It will stop beeping when
04:48the capacitor is fully charged.
04:50Now, it will not beep.
04:52If we do like this,
04:54it will give a small beep.
04:56This is our capacitor.
04:58It is fine.
05:00Now, the problem of PFC is
05:02that it is not producing PFC.
05:04That is why it is producing HC error.
05:06Now, we will check the rest
05:08with full detail.
05:10Now, we will check
05:12the voltage of
05:145V and
05:1612V.
05:18We will check
05:20the voltage of
05:225V and 12V.
05:24After checking this,
05:26we will know whether
05:28our station is fine or not.
05:30To check this,
05:32we will put it on series.
05:34This wire
05:36will be connected
05:38here.
05:40As I told you earlier,
05:42one will be connected here.
05:44Now, I will give the voltage.
05:46Now, we can check all the
05:48high and low voltages here.
05:50To check whether it is fine or not,
05:52the easiest way to check it is
05:54to put it on meter.
05:56This is our 5V and 3S.
05:583V are connected to the microprocessor.
06:00We will put the meter on 20V.
06:02After putting it,
06:04I will check here.
06:063.3V.
06:08Now, it is fine.
06:10Now, we will check the
06:12PFC.
06:14It is connected here.
06:16Is it binding or not?
06:18It is binding.
06:20Now, it is 5V.
06:22Now, we will check
06:24the voltage.
06:26It is 15V.
06:28Now, it is 12V.
06:30Our station is fine.
06:32Now, we will check
06:34the voltage here.
06:36Here, it is 57-58V.
06:40Now, the voltage is here.
06:42It must be here.
06:46I said 57-58V.
06:48Now, it is 57.6V.
06:52It is 0.6V.
06:54It means that
06:56everything is fine.
06:58Now, we will check
07:00the voltage here.
07:02See, here also
07:04the voltage is fine.
07:06Because it is in series.
07:08Now,
07:10we have to see
07:12I will mention the error here
07:14so that you can remember
07:16on whom we are working.
07:18If you have
07:20checked all other things,
07:22similarly, when you have to check it again,
07:24we have to discharge it.
07:28You have to see
07:30why it is like this.
07:32I will check the other things.
07:34Now, it happens that
07:36when this error occurs,
07:38even if it does not occur
07:40because of BFC,
07:42and it is
07:44Now, we have checked
07:46the other things.
07:48Now, the problem is that
07:50when error occurs,
07:52we have to check the other things.
07:54Actually, when this error occurs,
07:56its main purpose is
07:58less or more.
08:00But when it is more,
08:02it is suitable in AC.
08:04But when it occurs, it is less
08:06that PFC does not occur in it.
08:08In this, the microprocessor
08:10is installed.
08:12In this, there is a PSFC
08:14voltage protection.
08:16In this, there is a mirror.
08:18Let's say there is a wire connection.
08:20In that, when
08:22PFC is cut for some reason
08:24SMD is damaged
08:26and it can be damaged from inside.
08:28In this, the voltage is coming from here.
08:30But in this, it is understood that
08:32we do not get the voltage
08:34because it is disconnected.
08:36Now, we check the rest of the circuits.
08:38Whatever we have to check,
08:40we will not know in the screen
08:42or in the camera.
08:44I will check and tell you
08:46that you will not see anything.
08:48We can't clear everything here.
08:50See here,
08:52we see all these things.
08:54What is in it?
08:56Yes, yes, yes.
08:58See here, a lot of effort has been made
09:00to repair the kit.
09:02In this, PFC
09:04is coming from this.
09:06You should notice.
09:08See here, all things
09:10are disconnected
09:12to repair.
09:14It is all disconnected.
09:16See here, all things are finished.
09:18See here,
09:20all things are disconnected.
09:22See here, from all places.
09:24It has happened that
09:26these pins are of inode.
09:28See here,
09:30a lot of effort has been made
09:32to repair it.
09:34See here,
09:36see here,
09:38they have also put a jumper.
09:40See here,
09:42see here,
09:44see here,
09:46a lot of effort has been made to repair it.
09:48See here,
09:50see here, the bridge has also been changed.
09:52See here,
09:54a lot of effort has been made
09:56to repair it.
09:58See here,
10:00a lot of effort has been made.
10:02They have completely filled the kit.
10:04See here,
10:06a lot of damage has been done.
10:08If we repair
10:10such a kit,
10:12it is very difficult.
10:14But it will not work
10:16because it is so damaged.
10:18What should we repair it?
10:20See here,
10:22you can see it.
10:24See here,
10:26from here also.
10:28See here,
10:30the kit is very damaged.
10:34It cannot be repaired.
10:36There is no use of repairing it.
10:38Such a kit should not be repaired.
10:40See here,
10:42it is completely damaged.
10:44See here,
10:46you must have understood
10:48why there is an error.
10:50The reason is
10:52that the
10:54microprocessor does not know
10:56that
10:58the
11:00microprocessor does not know
11:02that the voltage
11:04from here is getting or not.
11:06That is why there is an error.
11:08It cannot be repaired
11:10because there is a lot of damage
11:12and a lot of repair has been done.
11:14There is no use of repairing it.
11:16The whole kit is damaged.
11:18It cannot be repaired.
11:20Thank you for watching the video.
11:22And
11:24if you like the video,
11:26please like it.
11:30Goodbye to all.
