00:00Assalam-o-Alaikum, look at this

00:02In this gate, there is a fault

00:04Like this

00:06Compressor turns on

00:08And see, it is closed

00:10This is a higher gate

00:12The only problem is that there is no error

00:14This is set temperature 16

00:16Check this

00:18It is running at 16, but what happens

00:20Look at this, there is communication

00:22And

00:24It runs

00:26And it is closed

00:28Now the problem is

00:30We have to check

00:32Is our coupler working

00:34Is there any communication

00:36Look at this, we set the meter

00:38At this range

00:40Here I put it on

00:42CRO setting

00:44Look at this

00:46Here we will check

00:48Look at this, I am checking the low side

00:52I set the meter

00:54Here I will check the coupler

00:56Look at this

00:58I am checking the coupler

01:00Look at this

01:02Voltage is coming

01:04Now when voltage is coming

01:06Look at this

01:08I am checking here

01:10Look at this

01:12Voltage is coming

01:14When I will check here

01:16Voltage is not coming

01:18If I come here

01:20Look at this

01:22Communication is happening

01:24Voltage should be like this

01:26If I come here

01:28On high side

01:30I am checking here

01:32If I am checking on high side

01:34Look at this

01:36Voltage is here

01:38I put it here

01:40Look at this

01:42I should get fixed voltage

01:44And the three points

01:46Both couplers

01:48Look at this

01:50Look at this

01:52Look at this

01:54I am getting variation of voltage

01:56I am checking coupler

01:58Look at this

02:00I am getting variation of voltage

02:02I am checking on next point

02:04Look at this

02:06If not

02:08I am checking here

02:10Voltage should be varying

02:12Look at this

02:14You can see

02:16I am checking

02:18You can see

02:20Now

02:22The problem is

02:24Compressor is switched off

02:26Compressor is switched off

02:28In running

02:30It is not working

02:32But this kit is working

02:34Everything is working

02:36I am checking IPM

02:38IPM is working

02:40Rest of the system is working

02:42There is no problem

02:44Now

02:46There is a problem in microprocessor

02:48Now

02:50Look at this

02:52Compressor is working

02:54But

02:56Communication is not working

02:58Communication is same

03:00After some time

03:02It will switch off

03:04Look at this

03:06It will switch off

03:08Compressor

03:10There will be no error

03:12In this

03:14Error occurs

03:16When

03:18Compressor

03:20Communication is not working

03:22Error occurs

03:24Error occurs

03:26But every time

03:28It will switch off

03:30After some time

03:32It will switch on

03:34In same condition

03:36I am switching off

03:38This is the problem

03:40In this

03:42Everything is working

03:44Error occurs

03:48Error occurs

03:50There is no problem

03:52Communication is not working

03:54Problem is

03:56Look at this

03:58Microprocessor

04:00I am removing this

04:02Problem is

04:04Microprocessor

04:06Problem is

04:08Microprocessor

04:10In same condition
