- in this video i demonstrated how to repair how to test troubleshoot & repair VCC3 Compressor dc inverter ac control board for fridge refrigerator
it is vcc3 2 speed dc inverter compressor control board using 2 speed variable frequency drive VFD. it takes 220V AC single phase and converts it to dc and then the microprocessor inverts dc voltage in 3 phase 230 V 53 Hz to 150 Hz. so that in this way the frequency of drive voltage for compressor is varied to get DC inverter technology for energy saving and quick cooling. thermostat signal is coupled to the micro-controller using optocoupler to change the output frequency
this circuit comprises a built-in SMPS switch mode power supply using TNY254 IC and a transformer to create 3.3V DC VCC for microprocessor. and a 6 V biasing voltage for half bridge SMPS driver IC IR2304 to drive MOSFET

Walekum assalam. Very nice this video 5:20
Excellent brother tutorial we expecting more from you I request to you Can you do complete fault finding and working principle of Inverter Air conditioner Pcb video Please
So useful 👌
عليكم السلام ورحمة الله ويركاته
hi sir at 22:30 is using SCOPE the ONLY way to test the output of the ic? i dont have a scope can i use a multimeter instead?
I have problem DC invertor board VCC3 3456 F4 , I have negative signal half curve only , Follow this video i have change IR 2304 ic but still same. Input pin 3 i get 15~16VOLT.Can you help me
can you please check the return feedback to microcontroller (from output terminals through resistor network
@@HaseebElectronics # Hi sir, Output signal from Triac ? Any output signal from IRS2304S ic to microcontroller need to measure ?
Assalamualaikum, sir would you please explain 555 ic.
yes brother i will try to do it soon
How to this pcb run with out compressor .i think this type PCB to run must wont compressor feed back voltage for run micro control
you are right. it starts and waits for the feedback through its sense lines which are connected to UVW lines through resistors
if compressor is not connected, that time the MCU disconnects the drive in few seconds
@@HaseebElectronics
i need run without compressor for test this type pcb.can i run 1mite this pcb.please help me....

Hi Haseeb, you are using probably isolating transformer for your scope? otherwise you can’t use Oscilloscop connected to ground without blowing fuse or demaged your scope
yes brother
i am using isolation transformer
i recorded a detailed video, it is now in editing
it will be uploaded next week
please check 468 & 469 on the same topic
Wa Alaikhum Slam!
Very informative video
Thanks for Sharing
Thanks sir of make this video 🤝🤝
Video quality is awesome and very helpful video
Hello Haseeb, I used a wave meter to measure 3 pins u, v, w and the results were normal. but my compressor still doesn't work, just vibrates then turns off, my compressor uses Jiaxipera, the compressor light flashes 9 times. Have you encountered this situation? I hope you will release a video about VCC3 Compressor Jiaxipera DC Inverter. Thanks
Sir good day
I'm just asking, how many five DC volt in one board of Aircon unit? Thanks gooday😊
Plz app always video urdu mein bnaya kro sab ko samaj aa ay gi ..thanks

Please sir, I am njakoi Charles . Am base in Cameroon. I love your lectures. I wish to connect with you on WhatsApp
A.OA sir how did u ON the pcb. Without compressor the processor will not out the gate signal upto my experience. Thanks
Awesome very nice informative vedio my dearest brother big thumbs up from me. thanks for sharing the details of the job.be happy with good health and happiness ameen 🛏️.
Very nice and technical vlog. Thank you for sharing. Have a good day.

Sir help me my inverter board PCB not passing current to compressor MOSFET and capacitors are good which components have fault and how can I check that help me
Hello. Please tell me the specifications of this diode. No matter what I tried, I did not get results. zd is written on the board, which should be a zener diode. The part number on the diode is 5AY. This diode is related to the inverter board of the refrigerator compressor. Thanks
😍👍
Thank you for sharing I wish you

Hi Why one of the IGBT's get fail in one phase. this in Hisens Inverter Refrigerator inverter PCB
Please do inverter aircon shunt and comparator how works and fault finding
HI. Thanks for your videos. These are very helpful. How and would it be practical to convert a VCC3 220VAC(2456) to 120VAC(1156)? I use the 120VAC(1156) but the 220 VAC(2456) are less expensive to buy for some reason. TIA.
Thank you very much Mr Haseeb for your efforts. Good method of faulty signal analysis. عليكم السلام و رحمة الله تعالى وبركاته.شكرا
Thankyou for the tutorial. I learnt that the input voltage to the VCC is 230V. I also learnt that the control votage is 3V. In a good VCC what is the voltage at each connection to the compressor?
Hi Bro, All output driver ic LIN,HIN no input 18V why please help
Very good repair
Sir please can you tell me
The part numbers of n channel and p channel mosfett in that vcc3 ... thankyou
The video was good, can you show us how to test a IC P1941 with seven pongs the number six pong is not ues?
We need samsung inverter refrigerator card test point with ocilescope
Thanks sir good good good
Most welcome
Kabhi Kabhi Urdo Mein Bhi Upload Kar Diya karen Mere Jeson Ke Liye RAB Rakha Mere Bhai
Please advise if you have any other simple method to test this circuit without the motor used for this.
Good vdo
Thank you Mr. Haseb for sharing your knowledge. I have learned very much from these two videos and from others. I encourage you to continue delighting us with more videos.

Many many thanks
Thank you brother for your patience and helpful videos.
Please accept my best regards and special thanks ❤️
Thumbs up done sir is there a build in photo triac at tny 254 ic tnv sir
my friend the igbt module maybe there are shorted diode inside thats why the output voltage drop..u can hang the output signal to ipm
you are right. if the protection diode is short internally then at full 3 phase operation the load arrives at main capacitor so tge DC rail fuse blows up in that case. and the echo signal to the microcontroller is hang. so the microcontroller cannot generate the next stepping pulse
Sir mera aap say siraf aik question ha woo yea k

Good morning 😁 awsome 🌼
9:20 - Tell me where you have your scope grounded, please. I have viewed several times and I am unable to see it. Also, is your scope battery operated?
Also, thank you for allowing CC. It makes it easier to understand if I missed a word you spoke.
Check and pause at 10:46 you will see a gray wire connected to test pin

Hi there.....i hope you can help me out to save some money. I live in Europe. I have a siemens inverter refrigerator. 2 months before it stops working and the motor does a like week 'bzzzzz' sound. I am amateur in this things but i have a hakko soldering iron and a fluke 179 multimeter and i know/have a little practice about soldering/desoldering. I have test all the 33uf electrolytic capacitors. 3 of the capacitors have regular values, +/-5%. One of them have if i remember right is 584 uf and the other about 48uf. I changed the 2 "faulty" capacitors and voila....nothing happended.....same as before. The reading of the new capacitors are equal with the old original ones that i repleace (high- 584-48uf). I notice that when i measure these 2 capacitors soldered in the board values are high, but when i dessolder it and test it again off the board the values are correct. Also the 2 'old' original capacitors that i took off the board have the right values 31.8/32.5 uf. I don't know what to do, should i replace and the other 33uf capacitors or no?
Please help me my friend!

Hi Haseeb and thank you so much for all your excellent videos! I have learned so much from all your SMPS videos and now about refrigerator inverter boards. When you have some time, would you consider doing a video on refrigerator main control circuit boards? I’m having some problems with mine and would like to understand more about how it operates. Thanks again so much and take care!
thanks a lot for your valuable comment
Great suggestion! i will try my best to arrange it
@@HaseebElectronics Thanks so much for considering this!
اتمني لكم التوفيق 🌹🌹 والنجاح الدائم
اسلام عليكم ورحمة الله وبركاته I have a vcc31156 and my input voltage is 120v I measured my voltage on the compressor phase line and is giving me 330v an220v but mv millie volt does that mean the board is still good?
