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!!!!
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!
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?
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?
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. 🙏🏻
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!
Very interesting video Haseeb about the Theory and practical repair regarding this VCC3 Compressor DC inverter control board!!! I learned again a lot today. question: I measured all 7 SMD small capacitors and have similar readings as you have in the video except for one: C201 (33microfarad) is only 0.11VDC, should be 6VDC. So I gues this one is the trouble maker. This VCC3 2456 23 is build in a Liebherr diepfreezer GNP 3376 20K. The problem is that when turned on the maximum he will go down is -2 degrees Celcius. There was quit some ice in the "No-frost" section in the top so I cleaned everithing and all ice is gone now. But still the same issue. Meanwhile I ordered the top PCB 6133 732-00 where both temp sensors and Defrost heating, FAN iare connected. But today after I saw your video the problm might lay in the CVV3 module... I checked/measured all folowing parts are working fine: Air Sensor (6kOhm), Evaporator Sensor(6KOhm), Door contact, Fan, Defrost Heating system(220Ohm),Compressor both speeds are working-initial speed High and low speed. Could you give me a hind Haseeb? MAny thanks again. Stephan.
In your situation it seems that the vcc3 board is working nicely Problem may be in thermostat board. Might be it is ending false switching or Please check optocoupler connected near thermostat connector (on vcc3 board) Otherwise if the board is turning on and the compressor is working, it means the board is working good. Just the thermostat switch is not sending the control commands to the vcc3 board for proper function You can try the thermostat or check wiring as well Because it is low voltage high frequency signal, loos or poor connection in communication makes improper behavior of the system
@@HaseebElectronics Many thanks again Haseeb for your tips. I measured again on that one smd capacitor C201 and now I measured 6.2VDC. So my bad. Indeed the CVV3 inverter is working fine. I also checked the optocoupler and this one is working fine as well from 3.2 VDC to 0.1 VDC once I connect 3.3 VDC on the thermostat connector. The wiring from the VCC3 PCB to the thermostat PCB is checked and fine. I still hope that the top PCB 6133 732-00 (thermostat PCB) that will arrive one of the next days will solve the issue. I keep you posted. Kind regards, Stephan.
I measured also the 3 windings from the compressor and had nicely 3 x 16.5 Ohm. So compressor is also OK. Finaly after exchanging the top PCB 6133 732-00 (thermostat PCB: 90 euro) the Diepfreezer is working again perfect. Many thanks for your very helpfull information Haseeb! KR, Stephan.
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?
Hi Mr. Hasseb thank you for the video. I have an inverter that is 120V input and want to know which is the neutral and hot and how important it is for the inverter to work properly ?
best regards unluckily i have no experience in 120V circuit. as i am from Pakistan and here it is 220V boards i will try to check some material, if i found something i will share surely
the reason for my question about which is the neutral on the board ,is that when I measure the voltage, on the 390uF capacitor (with voltmeter) I place the black wire on the negative of the capacitor and the positive on the positive of the capacitor and i read -63V. which tell me that it is reversed, right?
@@HaseebElectronics so I connected the neutral the correct way and now i see 350V pk2pk clean sine wave between each of the 3 phases, does it mean that the inverter is good? also, with or without 5V signal into the inverter i see the 350V on the 3 phases , is that correct?
It is not a good reading it mult square waves sampled circuit and. it's output meat drives through processor and driver ic and finally through igbt sets so I think you need to verify the circuit
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.
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😊

Hi I’ve been pulling my hair out! I have a vcc3 1156 115-127 to 230 53-150 hz and 3.3 amp on both input and output and single phase input to 3 phase output but now I discovered my original was what they call “Drop in” and the one I acquired is what they call “frequency” what is the difference?
Peace, mercy and blessings of God be upon you. Sir, is it possible to operate the inverter compressor with this card alone without installing sensors and a data screen, i.e. running a card only and connecting the compressor connection only without installing any wire in this board. Does it work constantly?
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

Ciao, che valore ha il fusibile collegato dopo gli IGBT?
33uf / 25v - 33uf /63v Would it be a problem if I replace it
if you select the higher value i.e 63v instead of 25v
while the capacitance is same, then it is okay
