The Quick Fix

If your control board looks like a FX-101 or FX102, 99% of boards were repaired by replacing capacitor C8, 47 μF 25 V.
Replace C8 with a capacitor with higher voltage rating, 35 V or 63 V if it fits on the same footprint and lead spacing.

Update
If replacing C8 alone does not solve the problem, replace CA1, 47 μF 25 V.

Next on the list of suspects to replace is C10, 2200 μF 16 V.

WSJ Wine Club - Control board FX-101

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
TWR325ESS and TWR320EBL

You came here because your wine cooler stopped working.
If you cannot find what you are seeking please start a new thread.
If you managed to fix your cooler please post your results on successful stories.
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.
