EdgeStar wine fridge problem.

Refrigerator & Freezer Repair
1

Thank god I found this place. Maybe someone can help.

I recently bought THIS wine fridge off a guy on craiglist. I got it home and fired it up and noticed a problem a bit later*I know I should have tried it out first:( *

The top partition control does not work right. If I adjust the temperature to say to 50 degrees, it will keep beeping and going up a degree sporadically until it is back at its max temperature 66 degrees. Then it will continue to beep for up to days randomly and if I try to adjust it, it does not register anything. It seems like it thinks I am pressing the button so perhaps a short or something. Anyone know of a safe way I can try to address this problem.

This thing was not cheap and 66 degrees is much to high for my wine. The bottom half works perfectly.

Thanks in advance for any help!

UPDATE- I just took a closer look. Im even more concerned because I noticed that the temperature it says on the display and the temperature it inside are off. Its about 5 degrees warmer on the inside. Everytime it beeps, the fan stops for a second and starts up again. The lights on the display flicker aswell

I cannot be of much help but can at least supply you with some info on it.

Here is a manual for it. It does have basic wiring diagram.

Here is a board for it. There is also some basic info in the support section.
EdgeStar Replacement Circuit Board for TWR215ESS TWR210EBL and TWR125S

Looks like there are 2 boards for controlling the temperatures.
You could try swapping the boards to see if the top now runs OK. Problem here ius that you may blow a good board if the problem is caused by something connected to the board.

Remove the board and check for a cold solder joint.
Cold solder joints are often a duller silver and/or may have pin holes.
Also gently wiggle the components to see if their legs move in the solder on the solder side.
A magnifying glass comes in handy here.

Check the capacitors (black cans with silver tops) for any leaking or bulging.

Check that the thermistors (NTC) are the same for top and bottom with a meter. ote meter polarity may make a difference here so try both polarities.

Thanks for all the great info. I figured I was going to have to get down into this thing to get it working again. My biggest concern is just breaking the whole thing haha
