    Default HDVS120 Vintage Select wine cooler thermostat is not working

    RepairClinic
    Model Number: HDVS120
    Brand: other
    Age: 1-5 years

    I have a Vintage Select Wine cooler which no longer gets cold enough. I had repair guy come and pur freon in it and it still would not get cold.
    He suggested getting a new smart board for the cooler but they no longer sell the part.
    His other suggestion was to get an external thermostat and bypass the internal thermostat.
    I'm having trouble s figuring out how to connect the external thermostat to bypass the internal thermostat.
    Which wires internally do I need to disconnect?
    Thanks,

    I hope you didn't pay that guy. Probably an automotive repair guy. When I have a refrigerator repair the first thing I do (and so does every other tech) is determine if the problem is in the sealed system or in the electronic circuitry. The sealed system consists of a compressor, condensor, evaporator and refrigerant. Most techs can tell if there's a sealed system problem (bad compressor, system restriction, or refrigerant leak) before they connect a set of refrigeration gauges. Once the gauges are connected to the system they can tell you exactly what the problem is.

    Refrigerators and machines like your wine cooler have a specific amount of R134a. Your wine cooler probably uses between 4 and 9 oz. of R134a. It says on the model tag. A little not enough refrigerant and the machine doesn't cool properly. A little too much refrigerant and the machine doesn't cool properly. How much R134a was added? What was the machines low side pressure? That "repair guy" took a bad situation and made it worse. You can replace every part on that machine and it still might not cool properly if the system is overcharged, undercharged, or restricted.

    You can't bypass the machines electronic controls without rewiring the entire machine and adding a bunch of new parts There is no internal thermostat. The machine uses thermistors and sensors that supply information to a motherboard. The motherboard controls the entire cooling system and compressor operation

    Hi Rick:
    that for the input. Actually the guy who tried to repair my cooler is pretty reliable but he still couldn't fix it. He suggested a new motherboard (company no longer makes it) or an exterior bypass for a thermostat. WE got a Johnson Controls Refrigerator thermostat in hope of bypassing the motherboard.
    Now we have to figure out how to wire it to the cooler. It appears that the compressor and the power are both working but the cooler is not getting cold enough.
    ??? What to dO?

    If the compressor is running continuously and there is no cooling the problem could very well be in the sealed system. What motherboard are you referring to? I didn't think this model had a board. Where's it located?

    Yea I agree with Rick, that's what I was wondering too Rick, this model is way to old to have a motherboard, it's not listed in the parts diagram either.

    Hi rick:
    the frig guy put some freon and sealed the cooler.
    yes, this has a motherboard somewhere under the digital display. I tried to order from Sears then they told me that they don't make it anymore.
    When you open the cooler door, the display is right on the top center of the front opening. The frig guy showed us how to unscrew it to take it off and there are
    wires under there, there's a motherboard with 4 wires, black with power to digital display and light switch, a white wire that goes to motherboard, a white wire from the motherboard to a sensor(thermostat, that's hanging in the cooler) a red wire that goes to the motherboard and a box connected to the cooler.
    I tried to submit a picture but had trouble.
    thanks Rick..

    Take a photo or two of what you're calling the motherboard or the controller part you're referring to. Then post the photos here.
