00:00Assalam-o-Alaikum, today we have a repair kit from Lahore.
00:12Let's see what is the problem with it.
00:14E7 error. No, this is E7 error.
00:19Now let's see what is the fault in it.
00:21If it is E7, then why, how and for what reason.
00:24Let's open it.
00:30Yes, it is all open.
00:53Now let's see what is the problem with it.
01:00It is E7 error.
01:08Now we have done the complete communication.
01:10See, it is E7 error.
01:12See, it is blinking, E7.
01:16The problem is that the light that is on in it, you can only see this.
01:22It has a capacitor charge, but the light of the IC is not on.
01:27Now the problem in this is that it has a problem of SMPS supply.
01:32Let's check why, for what reason and where is the fault in it.
01:36Now let's turn it off.
01:38We do not let the communication go on.
01:40I turned it off like this.
01:41Turned it off.
01:42Turned off the switch.
01:43Now I check where the fault is and try to repair it in front of you that it should be repaired on camera.
01:53Now I do the complete checking of it.
01:56What is the problem in it and where did it come from?
01:59We have to see the main thing first.
02:01I check all the SMDs on it.
02:12SMD is OK.
02:22Let's check this SMD.
02:24This is also OK.
02:26Now this is also OK.
02:29Let's check this one too.
02:33This is 47 ohms.
02:36It will be checked here.
02:38It will be checked here.
02:41This one is OK.
02:43Let's see how much it is in the camera.
02:53Yes.
02:54This is zero, so the detector is telling.
02:57Now I am going to check this one.
03:00This one.
03:01This is also OK.
03:03This is 10K.
03:05This is also OK.
03:06Now all these are OK.
03:25Let's put it on continuity and see.
03:27Its capacitor is short.
03:31Now let's remove the capacitor.
03:33The problem is in the capacitor.
03:36Now let's remove it.
03:45We have removed the capacitor.
03:48Now let's put a new capacitor in it.
03:51Then let's see what is the problem in it by turning it on and off.
03:55See this is the new capacitor.
03:57While putting it, you have to take care of its quality.
04:01Negative and positive.
04:03If you put it wrong, then all the work will be spoiled.
04:08Don't put it wrong.
04:09You can see the black side here.
04:13Let's see if the camera can show.
04:16This is the black side.
04:17This is its negative side.
04:19And this is positive.
04:20See here, there is a sign.
04:23Where is its sign?
04:26This is the negative sign.
04:27This is the positive sign.
04:28When we put the negative here, we put it like this.
04:33Let's check it again to make sure that there is no wrong sign.
04:36OK.
04:37See here.
04:38If it is wrong, then...
04:46Now let's put it.
04:48I will do its soldering.
04:49This is its soldering.
04:54We have turned it off.
04:55Now let's see from the top.
04:57You have to cut these pins.
05:00If you don't cut it, then everything will burn.
05:08Now we have put the capacitor.
05:10Now let's put it in series first.
05:13Let's put it in series and see.
05:14Let's see that our E7 was coming because the light was not turning on.
05:21And neither this light was giving us the signal of communication.
05:26That's why we are running E7 in series.
05:29I am running it and see that its light is turning on or not.
05:35See here.
05:36See here, its light is on.
05:38It came here too.
05:40And you can see this light blinking.
05:42Now in this, it is that our kit is OK.
05:47OK.
05:48Now we turn it off again.
05:50After turning it off, see I am turning it off from here.
05:53And I will discharge the capacitor.
05:57OK. It is discharged.
05:59This is our complete kit.
06:01It is clear in the error of E7.
06:03Now let's run it.
06:04We have to wait a little.
06:05Camera is off.
06:06Now as soon as it turns on, I will show you at that time.
06:10And now let's turn off the camera.
06:14We have put it.
06:16We have put this pin tractor.
06:17We have given it voltage.
06:18See, communication is going on.
06:20This reactor is installed.
06:21This is a one-ton motor.
06:22We have put it in it.
06:23This compressor is installed in it.
06:25If you like my video, then like it.
06:27Share it.
06:28OK.
06:29And see, if you are new to the channel, then subscribe it.
06:32So that you keep getting such informative videos.
06:35And if any brother wants to learn work, then he can also learn.
06:39Because this is the work of the future.
06:41And see, if you know this work now.
06:44Then obviously your employment will be better.
06:47If you don't know, then it's obvious.
06:49Because if you don't know this work, then you will be dependent on people.
06:52Because of which this work has to come in today's era.
06:56It is necessary for the person that this work should come to you.
07:00And with this, see, now as soon as it turns on, I will show you.
07:10See, this is our indoor motor.
07:13And our compressor is on.
07:16OK.
07:17This compressor is also OK.
07:18This is complete.
07:19See, the error of E7.
07:21This motor is going.
07:22The error of E7 is clear now.
07:26Your kit is absolutely OK.
07:28This is fine.
07:29OK.
07:30Yes, my brother can learn and do this kind of work very easily.
07:34In fact, you can do it at the customer's house.
07:37This is not a difficult task.
07:40This kit is clear.
07:42Thank you for this.
07:44Goodbye.
07:45Watch the video completely.
07:49And you will benefit a lot.
