Poster's Comments
Found this board to be functionally identical to the FX-101 but it is a different size.
PCB80812K1 MP-031 SH10241

Fitted and working ok. It is advertised as being a part for a Dihl WF-32.

This board also looks very similar:
PCB130312K7 HYS60-12-KR V-0 130C

Also just listing these similar parts to put everything in one place to aid others trying to find replacements:
TWR215ESS TWR210EBL and TWR125S

You came here because your wine cooler stopped working.
You can follow previous successful repairs at this thread:
https://forum.allaboutcircuits.com/threads/success-stories-repair-thermoelectric-cooler.101748/

Most of the coolers mentioned in this thread use the same control board, labelled FX-101 or FX-102.
Some boards may be laid out differently but they all appear to follow the same circuit design and part numbers and values.

#1 culprit is capacitor C8, 47μF 25V. Replace it.
The large majority of failed coolers were working again after replacing electrolytic capacitor C8, 47μF 25V.
It would be a good idea to replace it with a higher voltage rating, 36V, 50V, 63V if the replacement has the same footprint.
