Can anybody send me wine cooler circuit board wiring diagram? Did you get a manual from Newair ? I have a larger wine cooler 90 bottles with three modules of Fx102 . Its old wine cooler some 10 years old but good overall condition but two modules stop working . I am upgrading the system by changing the 3x TEC 12706 to 3x TEC 12715 I have very large heat sinks . The Fx102 power supply unit will be small so I will be using 12v 50A regulated power supply to feed all three TEC 12715 directly . I am able to find the 12v connection for the external hot heat sink fan connection cable from the FX 102 but cannot locate the 12v connection for the internal cooling fan . Can someone help it telling me which point on theFX102 feeds the internal fan . This will save me a lot of time in going through each point on the circuit board .Picked up a "works great" wine fridge that did not work great at all -- it didn't even power on! Upon finding this thread, I decided to replace the C8 cap with a big fat overprovisioned one (63V, 125C). As a total [de]soldering n00b it was a bit rough, but I managed to replace the C8 cap and it powered on!!! Felt like a million bucks. But here's the thing: the next day, I realized after closing it all up, I forgot to trim the long C8 cap legs and was worried about it touching something else over time, so re-opened it back up to do so and afterwards it no longer powered on.Tried desoldering and resolding the C8 cap several times (it was consistently too loose with the trimmed legs), but nothing worked, so I likely ruined the circuit board and/or the C8 cap from excessive heat. I really didn't want to buy a Chinese replacement board without a peltier fuse for $50 and wait weeks for it to arrive, but at the last minute I found a cheaper option locally under an alternative search term. So if you don't want to go through all this ballyhoo, just buy a replacement PCB from Newair:
