- in this video i demonstrated how to repair how to repair VCC3 Compressor dc inverter control board for fridge refrigerator
it is vcc3 2 speed dc inverter compressor control board. 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

Your explain and voice very clear.
Selamat malam terimakasih atas penjelasan yang sangat rinci tentang modul inverter Compreesor
I Watched nearly 4 minits ...
I'm not good enough maths..😢
Hi Mr Haseeb, question I happen to have a working VCC3 2456, which is 220V 2.1A 1PH input, and 230v 3.3A 3PH 53-120Hz output. And need to know if it will work with 115v 2.1A input?
Awesome, very nice repair

Very nice
Thumbs up👍👍
My refrigerator stops working and completely defrosts sporadically. It will start working several hours later and work for a couple of months. The amps from the motherboard
and voltage to the inverter checks out. Can the problem be the thermostat in the inverter.
Tysm or sharing.
thank you very sir for sharing...God bless.
Always welcome
Great Video👌😊Like 27 !Stay connected dear friend👌😊

Im very glad that your teachings are in english!
Hello, can anyone say how to test thermostat on refrigerator that uses this motherboard?
there are 2 types
1 is just send on/off signal (logic high or logic low to turn on / turn off compressor)
2nd type uses code based communication ptotocol to control compressor (most of time it is used in inverter compressor board) you can monitor the signal using oscilloscope 5 volt peak coded signals )
@@HaseebElectronics Thank you. I expected something like that. Unfortunately I am not such advanced with all of this. I can measure a resistance, measure a sensor, but sending on of signal I have no idea.
I have a bosch refrigerator with this motherboard and I have tested it as the compressor doesn't turn. Tested first the compressor:
16.0 ohm, then 16.2 and then another 16.2 ohm for the resistance between the three pins.
Then I tested the motherboard, on the compressor conector:
After few seconds since replugged, the motherboard sends about ten times about 57 volts to compressor (measurements on AC), it does this ten times and then it stops, but the compressor doesn't seem to turn, even between these steps.
I thought the pcb is the problem and bought a new one, it does the same.
Then I opened the no frost system and checked everything there :
Main resistance 0.479 kohm
Thermal security passed
Temperature sensor on main resistance about 500ohm
Second sensor(i don't know for sure if it's a sensor or a resistance as it is less visible, it goes to the rear side of evaporator) , about 450 ohm.
I have to test the fridge compartment sensor and if it's not this one, I don't know what could it be.
Thanks
it is my pleasure
Sir I m abhishek .I have whirlpool freez .Inverter board not passing current to compressor and Bulb is lighting inside freez . Capacitors and MOSFET are good but do not know why current not passing plz help
is the thermostat signal i mean the signal at optocoupler is connected correctly and it is working good??
@@HaseebElectronics yes sir .octocupler working good , ntc also beep at continuity, pf is also showing 1 .MOSFET and capacitor are good ....Sir how can I contact u
Mr. Hasseb thank you for sharing your insights. For me it is very valuable information, coincidentally I am repairing one but I do not have an oscilloscope or an inverter compressor to use as a load. my question is, can you use incandescent bulbs as load? or with the multimeter is enough. THANK YOU. 🙏🏻
nice vidio good job
Very useful and informative video.... very well explained.thanks for sharing this great tutorial..👍👍
Mr Hasseb: You have amazing knowledge of these systems. This video was so informative. Thank you once again for your time in making these wonderful videos. Bless you sir!!!!
nice

Bahut badhiya se bataya aap ne
Thank you for sharing your knowledge with us
I have a question and I would be very grateful if you could answer me
In the large black capacitor I get 311 volts, yours is 335 volts, does the lower voltage in my case cause the failure?
Hi! Very nice channel! I subbed! Stay connected, friend 💖
Mantap 😊👍 bos kuuuuuuu 😊 semoga sukses selalu 😊
hi sir my inverter is kikdr and the signal is thermostat
so do i still give 3.3 volts at signal pin and start the circuit?
can i know what should be the voltage at the 3 pin connector im getting dcv +-12v at all 3 pins is this correct?
i saw in other video they short thermostat to neutral and it starts the compressor but mine cannot
i have followed your video all the way to the chip b4 the compressor 3 pin but i cannot test the chip
is there another way to test the chip sir?
this video is THE BEST video to understand the repair!! keep up the good job sir!
Thank's for all information.please i want use 320 v solar energy for winding machine it is possible . Thank you
Thank's for all information.please i want use 320 v solar energy for winding machine it is possible . Thank you
thanks very much for sharing,very clear explanation...God bless.
Thanks a million. Please where does the feedback voltage comes from?? I thought you said the inlet was for a thermostat
Mashallah very helpful video
boss, pls make video about basic or simple board? we not know how to read pcb, journey of component, etc.
Awesome
7 likes very informative tutorial 👌💞👍
this video very important information we need to samsung inverter refrigerator test with osileascope
I have tested the compressor and my readings was I believe 6.7 ohms on all three legs and testing each line to ground was not shorted using a typical multimeter ! Does that seem correct?

How does the defrost relay work in circuits without a test button? Tell me how to run the test mode
شكرا مهندس حسيب بالنسبة الى الترانسيستور ات الستة هل هي موسفيت او igpt
Thnk u again for this video sir. I have question. Is the collector of the igbt always connect to posiitive voltage and the emitter always connected to (neg) or it can be also in vice versa?thnks sir😊
Good work
Nice video first time watching your video

Very nice tutorial upload Haseeb.
hi sir can i just check for hertz at the octocuopler? with out puting voltage?
I liked your video very much.it was very informative.id like to see the 2nd phase where you run the board with the actual motor.will wait for it.Good job!
Do you use an insulator transformer?
yes dear i have isolation transformer
@@HaseebElectronics could you share a diagram? Thanks a lot!
