Wine cooler temperature problem

[buchman]

Hi guys,

I am not sure if this problem belong here but, I will try.

I have a wine cooler that seems to work fine but the temperature displayed on the panel doesn't match the temperature inside of the wine cooler, I meen, the temperature inside the wine cooler is 12 degrees but on the panel it shows 23 and fluctuate a few degrees up and down.

I have replaced all the capacitors on the board and it didn't help.

Any one is got an idea what could be wrong?

Thanks a lot.

Sounds like a calibration problem. I do not know how your display is set up for reading the temperature inside the unit. I would think the display has a potentiometer that can be turned to match the temperature set to the temperature read.

What brand name do you have?

The brand is WINEBAR and the model is CS-70L.

Do you have a website for them? I have been looking for 1 hour and unable to find them.

"I meen, the temperature inside the wine cooler is 12 degrees but on the panel it shows 23 and fluctuate a few degrees up and down"
Pictures of the display panel? The temperature sensor should be going that display board.
Location of the sensor?

Unfortunately, could not find a website in English too.

only this one winebar.co.il

I think that the sensor is just regulating the temperature in the unit. That is not the problem. The problem is the digital display is not read the correct temperature. I would say the display has an adjustment.

That is why we need to see the pictures of the display panel board.

I was able to down load a translator. I had wanted to email them so I could find out who's Peltier device they are using as the devices I have seen do not stand up to the spec sheet that they say the do.

I agree.

Do you have a user manual that came with the frig? As there may be calibration procedures in the manual.

Unfortunately I don't have. I bought it from some guy that said that it doesn't cool and I thought I can fix it.
Now it is cooling but doesn't show the correct temperature.

So what did you do to get the cooler to cool?
So it shows wrong temperature but can you set it to other other temperature? Just want to know if it is still adjustable or not even though the readout is wrong.

Yes, the temperature is adjustable.

This is the first wine cooler that I have seen that actually works. I wonder what Peltiers it has in it and how many. I least now we can say WineBar makes a cooler that works.

It has only one peltier and a big heat sink on it. I disassembled it a few day ago just of curiosity.

Did you not notice the name or part number on the Peltier? You need to be very careful when you reassemble them. The direction of hot and cold is important. This can be found by holding Peltier in your fingers and then plug in the power supply. The minute you fell which is hot or cold then unplug the power. They will destroy themselves without a heat sink. How it lies on the heatsink is important. You want to make sure the wires have no stress on them when you tighten down the mounting screws. The reason for this is the Peltier can crack very easy. It is important to have thermal compound on Peltier on both sides. Not to much where it is squishing over the edges, but enough to cover all of it so it will conducted thermally. When the mounting screws are tightened you will want to make them finger snug on both screws. Then tighten them with a wrench slowly going from one screw to the other. You will wanted them to cause the Peltier to be secure but not cranked down.
