00:00Assalam o Alaikum,

00:02This is the IC for Kettai Repairing.

00:06There is an error of H3.

00:08You can see it clearly.

00:10There is an error of H3.

00:12There is an error of H3 because

00:14if due to some reason,

00:16the compressor gets overheated,

00:18then it comes.

00:20Or if the condenser is dirty,

00:22then it comes.

00:24There is an error of H3.

00:26But now, it is lying outside.

00:28Neither the condenser is dirty

00:30nor the compressor is overheated.

00:32The compressor is also cool.

00:34There is no problem.

00:36But neither is the overload

00:38attached to the compressor.

00:40Now, let's do the error of H3.

00:42Now, let's turn it off.

00:44After turning it off,

00:46let's see the reason

00:48for the error of H3.

00:54First of all,

00:56there is an error of H3.

00:58But this is correct.

01:00It is attached.

01:02We have to remove it properly.

01:04There is no problem in this.

01:06See this.

01:08Now, I am going to check it

01:10by putting the meter on buzzer mode.

01:12I will put this meter on buzzer mode.

01:14After putting the meter on buzzer mode,

01:16when we will check it,

01:18then this error,

01:20sorry, we should give it a buzzer.

01:22See this.

01:24This is correct.

01:26We have removed it.

01:28But now, what happens in this

01:30is that

01:32this often happens

01:34that the error of H3 starts

01:36and it does not come quickly.

01:38It takes some time.

01:40It is a simple thing.

01:42There are two pins

01:44attached to it.

01:46This one pin is

01:48attached here.

01:50It is straight.

01:52Often, this problem occurs

01:54that after this, the rest of the microprocessor

01:56reaches here.

01:58There is an assembly resistance

02:00of 330 ohms.

02:02It often gets damaged.

02:04It is of 330 ohms.

02:06But it gets dead.

02:08See this.

02:10Sorry.

02:12I have put it on 2000 ohms.

02:14Now, I will

02:17See this.

02:19It is dead.

02:21It is dead.

02:23Now, we will change it.

02:25I have this assembly.

02:27See this.

02:29This is the assembly.

02:31It comes in 3-4 sizes.

02:33This will be this size.

02:35This will be this size.

02:37I will remove this.

02:39This will be this.

02:41Now, I will remove it.

02:43After removing it,

02:45I will put it here.

02:47Then, I will check it and tell you

02:49that this

02:53See this.

02:55I have removed it.

02:57It is here. You can see it.

02:59See this.

03:01Now, I will put it.

03:03After putting it, we will check

03:05that our error

03:07has been removed or not.

03:11Now, we have changed it.

03:13Now, I will check

03:15its value again.

03:17See this.

03:19Its value is 330 ohms.

03:21You can see it.

03:23If I will check from this side

03:25then

03:27if I will check

03:29then its value

03:31should be shown.

03:33Where is its jack?

03:43See this.

03:45See this.

03:47It is 330 ohms.

03:49From inside the jack,

03:51I will zoom it.

03:53I will zoom it.

03:55You can see both together.

03:57See this.

03:59It is 330 ohms.

04:01I have checked it from inside the jack.

04:03We have changed it.

04:05Now, we will run it and check

04:07that its error has been removed

04:09or not.

04:11Now, we will run it

04:13and check it properly.

04:15Now, we have installed the jack.

04:17Now, I will turn it on.

04:19Let's see that

04:21our H3 error

04:23has been removed or not.

04:25See this. It is on.

04:27Now, its compressor will be on.

04:29After checking it,

04:31we will turn on the compressor.

04:33After that, we will turn it off

04:35because there is no heat sink

04:37installed in it.

04:39Now, we will repair it.

04:41Obviously, we have to keep the board here.

04:43So, we have to keep it without heat sink and box.

04:45If we keep it in the box,

04:47then it will not work properly.

04:51See this.

04:53Now, its compressor

04:55is on.

04:57And

04:59the error of H3

05:01has been removed.

05:03Its SMD was not working.

05:05We have changed it.

05:07So, this was the error.

05:09If you like the video,

05:11then

05:13please like it

05:15and subscribe to our channel.

05:17Now, we have

05:19covered the error of H3.

05:21Now, we don't run it for long.

05:23We will turn it off.

05:27Thank you for watching the video.

05:29May God protect you.
