00:00assalamu alaikum it's cut out for repairing because there is a problem that the customer

00:21told us that there is a problem that the compressor does not turn on but the error does not appear

00:28enough time it starts running but it doesn't get error we have connected this compressor after

00:34communication and see it is complete now i will give voltage to it in series i put and see this

00:41is that first of all i see this now it is turned on it now has this motor which is an indoor blower

00:50motor i installed it look they are singing but it happened this is about what has been done in it

00:58now this has turned on suddenly and once it is on look at what it is doing see this it is on it is

01:05off look at it now as it happened this temples again activating the relay which then turns off

01:13the relay is being activated see this all right this is how it is occurring when the relay turns

01:18on the load increases on it there is a shot in it okay it is short but when there is no error

01:22consistently it becomes a big issue see this is how it is switching editor and this pgc cuts it off now

01:30we see the issue is that the pcb in its order belongs to the customer it knows our pcb is fine there is no

01:38fault in it it is okay but this consistently shows you that this is such a fault that there will be no

01:43error in it absolutely no error see this it does not produce errors and it switches this way so when

01:51we turn this off now i will connect this complete circuit this is the indoor and outdoor pc i will

01:59give it voltage now i'm checking what's inside this let's find out now i'm starting to give current

02:07from this this is for communication this is our l and this is n now i'm starting to connect this with

02:14the line okay and alongside this one in this there's a small relay that's installed it doesn't turn on

02:24until that time it won't activate until its time limit is reached when it signals the microprocessor

02:31activates the relay but we will proceed now what happens is that when we connect it in series c

02:38nothing will happen now i connect it like this now i'm using the help of the nozzle to connect the

02:45relay from here if i get the green light i will check i know this line is okay it is clear that

02:51then along with that now when i touch it i will see if there is an issue in the dc look at this

02:59light see it is shining brightly from here look look look well right there is something here i am

03:09checking what this is first i will check its heat i will remove the thing after that we will see what

03:19the problem is in this situation what is the issue in this what is the issue in this what is the issue

03:37in this what is wrong what is wrong what is wrong what is wrong let's check the diver first we will check

03:45it let's check it let's check the bazaar for any problems or issues

03:51now we will check all items at the bazaar your turn to check

04:00next we go to the ipm there's a problem on the high side but not on the low side

04:08now we will check these things you will turn the diver and we will check the first reading

04:14the third reading should be slightly lower let's check the diver now

04:23one side is okay and the other side is fine too now we check the

04:32the reading of this unit is fine and this gate is also okay

04:40now the problem is that switching is taking place as you saw

04:45the lab is in a switching it has just disabled and get

04:50what happens here is that debbie i am sorry this microprocessor started switching while this

05:00the driver is connected this is what we need to check the azee and the draft c1

05:07this is what we need to check the azee and the draft c1

05:14these components of a pc gate the assembly is in call for it

05:22we will check this here this is 2.2 we will check the seating

05:29do you see his reading check it out here you can see it here

05:36this is the reading of it here when i'm checking it

05:40so it's straight here to drive it here it see it here it drives this ic

05:47see two and it's here to point to mega but show it see this

05:54johaye zero zero shogari it means it has been short now there are two reasons for it being

06:02short which is this is what our eye is attached to it can also be short due to which it is coming

06:09and this too now we are thinking that we will take it off and we will not pass it

06:16how is this happening here

06:20see this i have now attached it now put it after taking it off let me see

06:28whether his condition is the same or not now after that we will see that he

06:35what is it that its ic some driver ic is bad its or our it is some other problem in this we

06:42this we now in this i removed this registration

06:47now after removing the resistor i started to check it again

06:54it does we have now removed the region since but with it now the igbt was also suspect removed it

07:02now check it

07:04is it bad or not bad what is the problem it is thinking repeatedly

07:09what is the problem i will check it now i will check the meter here for you

07:14i put it in front of him like this i will check it first on

07:23if we check this here it's perfectly fine there's no damage or anything it's completely okay

07:30now i will give it voltage again let's see here where i can connect two variants because we need to discharge this

07:39the second thing is that there is a relay here when communication is needed this relay turns on

07:46now we will check the circuit directly by turning it on

07:50we need to check this this is our red wire the positive side

07:54i connected the meter to dc at 600

07:58i do this to ensure i need to find out if this capacitor has fully charged or not and whether it has discharged

08:05this has charged and discharged whatever it is it shows up on the meter right away

08:10so i connect it here

08:12now we will give it current here i will connect the series here see i have connected it sorry

08:17now this i didn't set this reactor i will set it now

08:21see this i've set the reactor here now i need to reset this relay since it won't function without communication

08:28look i've given it current now there's no voltage noise here like before i will check what it does

08:36see this now it's charged from the capacitor the voltage is complete look it's boosted this indicates that the

08:45the iebt gate gets current repeatedly which is why we don't encounter errors

08:52after a long time after five to seven hours we woke up sometimes an e6 error happens but it doesn't come quickly

09:00this was the problem now we will do it what about the driver ic

09:05we will remove it and check if it's faulty or not we will change the driver ic and the pfc will also be fine

09:12and along with this the entire circuit will function properly with the pfc we took out the i gbt before testing

09:19now we will check if the circuit is ok and if the compressor is on

09:26if it is we will add the driver ic

09:29this kit is good

09:33we have finished communication and i removed the i gbt it's not here this is full control

09:41here this is full communication

09:46i'm starting this now look i'll connect it directly

09:51this is off and my brother has turned it on

09:54this is the temperature see it's ok

09:58let's see if the compressor starts but we won't keep it running for long

10:04no pressing is attached to the ipm

10:11let's see if this turns on or not or what the issue is we'll find out soon

10:17if this turns on correctly we will install its ic driver and turn it on with the i gbt

10:25come on see brother our compressor is now on

10:29ok look this compressor is connected

10:34look this compressor has turned on which means our driver ic is faulty

10:39it's defective see this

10:44this compressor is hooked up

10:51it has been

10:58make it work it has been done

11:00look this compressor is connected it has been done

11:04i didn't set this reactor i said it

11:06see i placed this reactor here now i will reconnect it since it will activate with communication

11:12communication see I provide a current now there's no voltage noise look it was

11:18shot before now I check now it's charge see the voltage is complete this

11:30indicates that deep receives current at its gate repeatedly which is why it

11:34functions no error an error comes after a long time five to seven hours later then

11:43any six error shows otherwise it does not come quickly

11:58following this I will create a second video demonstrating how this change was

12:03implemented and how the PFC has been fully completed thank you for viewing the

12:08video take care
