- 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

Sir thank you sharing idea I have learned so much. Helpful and informative
best regards
Walekum assalam. Very nice this video 5:20
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?
Thank you brother for your patience and helpful videos.
Please accept my best regards and special thanks ❤️
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
Wa alaikum asalam. Great knowledge 👍👍great sharing jazak Allah
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

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?
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
Very useful electronic circuit guide. Thank you for sharing offline
Very nice and technical vlog. Thank you for sharing. Have a good day.

On Kar k rakh dia hai. Full play k liyay.
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!
A.OA sir how did u ON the pcb. Without compressor the processor will not out the gate signal upto my experience. Thanks
So useful 👌
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.

Sir good day
I'm just asking, how many five DC volt in one board of Aircon unit? Thanks gooday😊
The video was good, can you show us how to test a IC P1941 with seven pongs the number six pong is not ues?
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
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
Very clear explanation.Thank you!!
بارك الله فيكم
hi , thanks for exponation , I want to tell a question . I have a board like this but in dc tension don't have 330 VDC but tension isn't stable. i get 300V 290V . there is something no working .Cold u please tell me somthing about that problem ? thank a lot
@@HaseebElectronics is a 220 V ac , I try to replace main capacitor with another with more microfar but its the same thing , mosfet at first impression with multimetr sound like good .

Hi do you know of a good tester kit for testing these compressors?
Beautiful video Haseeb, interesting Repair VCC3♫
going to greet, big sunday, thumbs up!!!!
Please advise if you have any other simple method to test this circuit without the motor used for this.
Bohat achi vedio hai sir aapki shop kahan hain?kya aap serves dety hain?
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?
You are the best👌
i am thankful
Good morning 😁 awsome 🌼
Hi. Thanks for your videos. Is there a practical method to convert the VCC3/220VAC to operate with 120VAC? TIA
if the board have 2 capacitors, then you can use that central pins of capacitor can be grounded
but some boards have voltage sensing line, which gives the voltage sensing a voltage divider network. in that case you have to redesign that voltage divider network to give voltage value to microcontroller
@@HaseebElectronics Oh I think I see the "voltage sense line" is sensing the voltage of the bulk capacitor and connected to microcontroller ADCIN0. ?
R115(620K), R116(620K),R117(620K),R103(12K) are the divider?
@@rogerschelling3162 yes there is special line to check the dc voltage to adjust frequency and voltage
@@HaseebElectronics If I am looking at the right divider resistors R115,R116,R117,R103 then interesting - they are the same value on the 220VAC(2456) inverter as the 110VAC(1156) inverter.
The 110VAC(1156) has 2 capacitors 820uF/200V. The 220VAC(2456) has 1 capacitor 400V/220uF.
wonderful. done boards have this vsense pin voltage divider different than 220
now you can modify it easily
if the 400v/220 if
have connection points on the board for another capacitor
then install another 200 volt capacitor
and take the central common point of capacitors to the bridge input line
and modify the input circuit as the 110 volt board
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
Thumbs up done sir is there a build in photo triac at tny 254 ic tnv sir
Thanks sir of make this video 🤝🤝
بالتوفيق والنجاح الباهر باذن الله 👍

Could u please one problem ,gree odu when I test it without compressor was normal but I connect with compressor make the ipm broken
@@HaseebElectronics really thank u very much
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 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!
