Replaced both heat sinks (upper and lower) plus the PCB on my Whynter WC-321DD dual zone wine fridge. One side was completely dead, now works great, like new. One note, upper and lower heat sinks are identical and interchangeable, even though they have different part numbers. Also each heat sink requires soldering 2 wires in to PCB, but very easy with small soldering iron
Ambient service was great with 2-day delivery of my parts, all well packaged.

The part fixed my problem, but it took a little extra effort, as the wiring was from the top instead of the bottom as in the original. So I had to add some extra wire and reverse the installation of the pcb.
