Thank you all for your extremely helpful information. Thanks to all the information provided in this thread I was able to fix my Wine Enthusiast 6 bottle wine cooler with the PCB140411K2 board. In addition to C206, CA1 and C8, I also had to change the C10 (1000uF 16v). I replaced the 47uF 25v capacitors with 47uF 35v, and the 1000uF 16v with 1000uF 35v all 105C. I also seated all 4 capacitors about 4-5 mm higher and I made sure that they do not touch the 2 large resistors next to them. Out of the 4 capacitors that I replaced the 1000uF was measuring only 324uF. One of the 47uF was 35uF, the second 47uF was only 26nF (Nano Farad) and the third 47uF was 0.4nF (Nano Farad). I am also including the picture after replacing the 4 capacitors (yellow arrows pointing the 4 capacitors). Thanks again.View attachment 261513

Who knows? Nobody knows. Try it and find out. Report back your findings.

For starters, replace C8, 47 μF 35 V.

My board is actually a Pcb161021k2 but looks exactly like the one i replied to also does it say the names on the board so i can replace them?
