Re: EuropAce EWC 913 Wine Cooler power board fuse blow /shorted
It works! Had to replace the Viper22A chip, two capacitors, two diodes, one resistor and the optoisolator, but now it runs. The temperature display is faulty, it displays rubbish, so I assume that whatever damaged the power board also damaged the display driver, but that's more of an inconvenience than a serious fault.
Thanks for your help in finding my way through an unfamiliar board.

Re: EuropAce EWC 913 Wine Cooler power board fuse blow /shorted
Can you check what value R35 should be? Mine reads brown black brown, which should be 100 ohms at 5%, but it measures 193 ohms. Before I change it, I would like to be sure that the colours haven't faded and that yours is 100 ohms.
Diode D1 is short, D2 measures OK, but I'll change it anyway. Other resistors measure OK.
I'll change the optocoupler as I can't be sure what I'm measuring and the cost is trivial.
Best regards

No, nothing there.
C1 (33uF 400v) has 325v across it, so volts are getting that far.

Re: EuropAce EWC 913 Wine Cooler power board fuse blow /shorted
I thought it was too easy!
I've replaced the VIper22A switch-mode chip, and C1 (33uF@400V) and C2 (47uF@25v) and put it all back together. Although the fuse F1 doesn't blow any more, and F2 is intact, the cooler doesn't start up and there's nothing on the display.
Any ideas as to what I can check next?
Thanks

Fortunately, the person who removed the board took the precaution of photographing the connections before removing them.
Hopefully, when the parts arrive, I should be able to repair the board.
Thanks to Lotas for their help.

Re: EuropAce EWC 913 Wine Cooler power board fuse blow /shorted
Thanks, but which of the wires with the three two pin connectors goes where?
1) I have one connector with a single green wire coming from the display PCB.
2) I have one connector with a black wire and a white wire.
3) I have one connector with two black wires.
On the board:-
I have one socket marked CN1, which you kindly identified as being for the fan.
I have one socket marked NTC1
I have one socket marked LED
I have one socket marked OUT.
Four labelled...Leave a comment:

Thanks Lotas,
Unfortunately, the video shows a different board. The picture you posted is the right board, but the white two-pin connectors are the ones I'm not sure of. There are two sizes, and two sockets for each size.
The Display board has the larger 6 pin connector, and one small two-pin connector with just a single green wire. I'm assuming that connects with NTC1, as that has one pin that goes to earth. It could equally connect with CN1, but as that's labelled as a fan connector, I don't think...Leave a comment:

Re: New Members - please post your introductions here
Just joined, having a wine cooler to repair.
My 'normal' area of expertise is with audio equipment, having been active in the Broadcast industry all my working life. I'm also quite active on one or two audio forums, but only those dealing with technical matters.
Pleased to have found this place, hope I can keep more stuff out of landfill with your collective help.

Re: EuropAce EWC 913 Wine Cooler power board fuse blow /shorted
Just found this forum and registered, and hoping members here can help me.
A family friend just gave me their Wine Cooler to repair, and this thread has already greatly helped in identifying the VIPer 22A on the power board as faulty, so I have a replacement on order.
However, the hanny10-12C power board had already been removed, so don't now have a record of where each of the wires go. I'm assuming that the red and black plugs go in their respective coloured sockets, but there are two...Leave a comment:
