I bought a thermoelectric wine fridge that wont cool down past 71.2F. Here’s what I know: I’ve changed out the Peltiers twicePeltier IS receiving 12.4 voltsControl board is also receiving 12.4 voltsBoth red and green lights on the control board are alight and NOT blinkingAll fans work just fine and have good bearingsNone of the capacitors look damaged. I realize they can be without looking like it…but it doesn’t seem like they’re the problemDisplay works just fine, as does the interior lightUsed fresh thermoelectric grease I’ve checked that I have the node installed with the cold side towards the cabinet multiple times, for posterity’s sake. I checked the node by connecting the red and black wires to their corresponding wires on the control unit/board and plugged in the power cord. One side immediately got hot - I wrote “cold” on the side that didn’t. Could there be something wrong with the thermostat making it so that the control board thinks the interior temperature cold enough already, but isn’t? What am I missing?

Hi, Here’s the VT-12TEDS service manual which whilst it is not exactly the same model may still be of some help. It describes how to test the temperature control to make sure that it is OK. The temperature control board itself is not that cheap to replace but maybe you can find the problem. Hopefully a start.
