I fixed my Bosch refrigerator's inverter box using your video as a guide. Thanks for pointing out the capacitors that are problematic. I used needle nose pliers to twist off the old ones, cut the leads on the new ones short, bent them at the end so they can rest on the pads, and soldered them onto the board (paying close attention to polarity). I used 33UF 50V capacitors -- $5.00 CAD at Sayall. I put everything back together, plugged in the fridge, and it works. The fridge is cooling down and the compressor is running and warm. The inverter box was going to cost me $300 with a one to two week wait. Thanks again.

Great video, I need help diagnosing issue with my Kitchenaid 48" which has the same VCC3 and the main control board (W102194630). I have repaired the main control board by replacing all relays and capacitors and utilizing a new VCC3 board. The issue now is the compressor never stops and goes much below 0 where it's set at. I think this was happening before as well and thats what took the vcc3 board out. I have checked 2 thermistors and both read 2.6Kohm at 70F. I am at a loss as what to do next.

Hey there, I was wondering if you could help me with a problem. I used this video as a guide to try to troubleshoot an old fridge (GE profile, 2007 I believe) that gave out around 5-6 years ago. It seems like the compressor won’t turn on, but after some snooping it seemed the inverter board may have been the issue. Like you did, I removed the SMDs and replaced them with new capacitors, and I did have a few of them test wonky, so I thought I was on the right track. Unfortunately, when I tried putting the inverter back into the fridge, it didn’t work. I get a short, loud buzzing noise (which seems to be coming from the inverter board itself, yikes) when I plug it in, which lasts for a few seconds. Other than that, the only noticeable change is that there is a soft gurgling sound that sometimes persists for a few minutes but eventually goes quiet. This gurgling noise would happen a bit before the capacitor replacement, but it seems louder now that there are fresh caps on the inverter board. Now it seems as through the itself compressor is malfunctioning, plus my added worry I may have broken else something when I repaired the inverter. When I tested it in the fridge, the inverter was getting the right inputs (120 vac and 5 v pdc at 50-60 Hz). Still, no vibration or noise from the compressor at all. The compressor tested fine electrically, but I’m having trouble finding tips on how to determine if the compressor is seized up or if the inverter may still be malfunctioning. I also wanted to try building your tester circuit, but it seems useless when I know that the inverter is getting power fine in the fridge. Are there any ways I could try to safety jumpstart this compressor and maybe ‘knock it loose’, so to speak?
@electronicsprojects470810 ай бұрын
I have never found a bad compressor cause an inverter to fail. With a short on the board, that can cause other parts on the board to fail, also, I have seen many different types of failures on these boards down to ant sized smd capacitors, so helping by proxy would not do you much good. My recommendation for your situation is to replace the inverter, maybe find a good used one on EBay if you don't want to spend a lot of money.
@preservetheunion925810 ай бұрын
@@electronicsprojects4708 thank you very much for your insight. I think I see your point, and that’s probably the best advice I could’ve asked for. It makes a lot of sense that the board itself might have more faults than just those capacitors. With how sensitive they are, I imagine that sequential failures between connected components can be common. I wish I had enough skill to have tested it more thoroughly, but I hoped that perhaps replacing the capacitors would get the job done. Since that wasn’t enough, I had already started to figure that the work it would take to make sure the board was working properly wasn’t worth it when I could just buy another. I’ve seen some online for between $100-$200, which is still a lot less than a new fridge. I knew going into this that if was a bad compressor, repair wouldn’t be worth it, which is why I started with the inverter. The motherboard was sending it the proper power and control signal , but the compressor still wouldn’t come on, so I’ve been holding out hope that it is the inverter and not the compressor. However, knowing a bit about how important those caps are for the functionality of this board, and that the majority of the ones I pulled off tested bad, it, I should’ve given up after replacing them didn’t work, but I thought it was worth seeing if you might have any other tricks up your sleeve. It’s alright, I knew it was a Hail Mary. I’m a total novice, but I had a bad feeling the circuit had other issues. One of the caps I replaced (one of the little 33 microFarad ones) tested at over 330 microFarads. After replacing it with a brand new 33 mF cap and testing the board, I found that the new cap I had installed was now reading at ten times it’s ratings as well. I’m certainly not well versed enough to guess at what that might mean, but I’m pretty sure erratic behavior like that in this circuit is, uh, bad. Do you have any notions on what happened there? I really appreciate your input on this, and I think I will follow your recommendation and see if a different board solves the issue. Thank you for saving me the headache of trying to wish a dead hunk of silicon back to life. I did have one more question regarding what you said, about it being unlikely that the compressor failed first, causing the inverter to fail. What about the reverse situation? If the inverter was indeed what caused the problem, can you give me any odds on if it could have subsequently damaged the compressor? Thank you again for sharing your knowledge and expertise to help me with this project! You’ve been a great resource and inspiration draw on to try to tackle this on my own. I truly would not have gotten this far without that, and this makes you awesome in my book!

Can u mention the value of changing capacitors bcoz I can't clearly understand your voice. Thanks

Is there any way to bypass this inverter ?
@juancarloslozano33746 жыл бұрын
No, you cant bypass the inverter. The inverter provides variable voltage to the compressor; this is for savings pourposes sending more or less voltage to the compressor and therefore it consumes just the amount of electricity required to keep fridge at the desired temperatures. The only wy to bypass the inverter is changing compressor for a old kind unit, a reciprocating one who works always at the same consuming electrical rate, so is more expensive in terms of annual electricity cost.

Thanks where can I get those capacitors brother

33uf / 25v - 33uf /63v Would it be a problem if I replace it

higher voltage is ok, replacing with a lower voltage is a problem.

At 5:32, the capacitor shouldn’t 35v 220 mf, can you double check? My inverter have this label m3 220v.

They are not all the same, you would have to cross your capacitor numbers to the manufacturer data sheet online to see what the specs are. They use different brands for the caps.

pura repetidera de lo mismo, todos los videos de reparaciones de las tarjetas les cambian los capacitares, tengo una que se los cambie y no funciono

Hello, Could you tell me how to connect the signal to CN05C? I want to test the inverter.

Ideally, you need an 5 to 15 volt positive DC square wave, you can use an Arduino to get a square wave output, 50 hz to 130 hz
