Help Needed with EuroCave Revelation (2014) - Suspected Main Control Board Issue

I have a 2014 EuroCave wine cellar, model V-Revel-L. Recently, it stopped freezing, but there are no error codes displayed.

I contacted Wine Enthusiast tech support, and they suggested that the issue is most likely with the Main Control Board. Unfortunately, the unit is no longer under warranty, and they advised me to contact a local refrigeration company.

I have some basic DIY skills, including soldering, and I’m hoping to get some guidance from the community. Specifically, I’m looking for:

  • Advice on diagnosing and fixing the Main Control Board issue
  • Service manuals or electrical diagrams for this model
  • Any tips or experiences from those who have encountered similar issues
