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.
