Re: Wine Fridge Power Board
The temp outside the fridge is about 69. The fridge is maybe two cubic feet. It wasn't near as warm on the back of the unit when I got home from work.

Re: Wine Fridge Power Board
I let it run all day today and I have readings of 72 and 64. I put it back on top of my regular fridge where it has always been and the temp jump to 77 and 69...better but nowhere near where it should be. I haven't measured voltage yet.Leave a comment:

Re: Wine Fridge Power Board
All four fans inside and out are working fine. And yes, it's actually about 6.3A each. I only ran the fridge for about an hour and the one side actually warmed up from 78 to 81. The other stayed around 73. I have them set at 54. I made sure the chips were facing the right direction.Leave a comment:

Re: Wine Fridge Power Board
I've messed with this thing on and off for weeks. The two peltiers were drawing between 3-3.5A. I put a pair of 12709's in to see what would happen. They draw 6.5A and don't do a thing. The back of the fridge is super hot. I used a good thermal compound on both sides of each chip. I give up.Leave a comment:

Re: Wine Fridge Power Board
Actually, CN2 is open on the left board.
I will test the amperage soon. I appreciate the input....Leave a comment:

Re: Wine Fridge Power Board
Was that supposed to be a link? I guess I can search it. My fridge is a Wine Enthusiast 12 bottle dual-zone that was about $200. I prefer to keep it. I noticed that the ones I bought were 60W and there are both 72W and 92W available as well....Leave a comment:

Re: Wine Fridge Power Board
That could very well be. I've seen an improvement since swapping the microcontrollers but not where it should be. This morning I had one at 64 and on at 69. I got these Peltiers on eBay from China. Is there a "local" source of choice?Leave a comment:

Re: Wine Fridge Power Board
I found the removable chips and swapped them in. Both sides are set at 54 and I currently have one side at 64 and one at 71. Both were five degrees higher when I shut it off to swap the chips; so it's cooling but very slowly and not like it should. This is really strange. The fans are running fine.Leave a comment:

Re: Wine Fridge Power Board
Correct; two boards, two peltiers. They both held temp around 52 degrees in my basement which is about 55. I brought it upstairs and one side maintains a temp of about 62 and the other is not doing any cooling again. The fan is running though. I don't expect the two to be the same; they never were. I have to believe that there is only one temperature sensor. The jumper wire I mentioned previously connects the grounds of the CN4 pins from each board. I didn't have this connected in my final testing in the basement and all was well. I did...Leave a comment:

Re: Wine Fridge Power Board
The boards are exact. I pulled the jumper wire that joins the two boards and it seems to be running like it should. The left side fan slowed and eventually stopped again but I happened to check the temp on that zone and it was where it should be. My basement where I'm working on this is cool so maybe that's been part of the deal all along. I would think the fan should still be on the whole time. I just don't get the beeping coming from the boards.Leave a comment:

Re: Wine Fridge Power Board
I took some better pics. The thick yellow wire (chassis ground) was in the center of the old boards. The new ones didn't have that spot available so I attached it next to the ground for the Peltier.
The second pic is of the right side. Each side has CN1 which I believe is the on/off switch for the lights inside each side or "zone". CN3-Fan I have for each exterior fan on the heat sinks. CN4-Fan is a single wire that joins both boards. CN5-LED-Fan is a 3-wire port for the front LED panel and interior fan; one on each side. The...Leave a comment:

Re: Wine Fridge Power Board
I checked everything over again tonight. I did find that the two big caps that I replaced on each board were 220V instead of 200V. I'm not sure how that happened but that is the only thing left I can find to try is to put the originals back.
I did this because I've heard over and over that these boards come with junk caps so I replaced all with Nichicon.Leave a comment:

Re: Wine Fridge Power Board
The left side runs but throttles down to half speed after 20-30 minutes. The right side stays running fine. Both sides cool. I don't believe there is a door switch but I'll double check.Leave a comment:

Re: Wine Fridge Power Board
Well, now both boards and both Peltiers are new. I changed the first chip with the first board. I am at a loss.Leave a comment:

Re: Wine Fridge Power Board
I had a spare Peltier that I swapped in this morning. The fridge stays running now but the left side throttles down after a bit. The voltage is exactly half the right side to the Peltiers. All connections are tight. The only thing I am not certain on is the single wire that connects to both boards. I have to connected to CN4-Fan on both. I have the fans connected to CN3-Fan. I still hear beeping from both. It sounds like a hearing test; high-toned and very faint.Leave a comment:

Re: Wine Fridge Power Board
I have been messing with this on and off for a couple weeks now. I didn't mention every little step but I confirmed the fan was good when I noticed it wasn't running. I didn't have a quick failure on a new board. This unit has two boards and the other died (or so I thought) after replacing the first board. I replaced all caps, diodes, and transistors on the second board. I had the same issue so I decided $48 for a new board was better than the time I had already wasted to this point. I plugged the new board in and now it does the same darn thing; runs...Leave a comment:

I'll probably have to pull this back out for better pics...not sure if you can tell anything; or if there is anything to even tell....Leave a comment:

No, I replaced every single cap. I'll get a pic later.Leave a comment:

Wine Fridge Power Board
I found a couple helpful articles on here from people having the same problem as myself. I have the dual zone Wine Enthusiast 12-bottle fridge that lost cooling on one side. There was no power to the fan so I knew it wasn't the thermocoupler. I purchased a new board before finding this site but I immediately replaced the caps on the new board with Nichicon. Things were great for a few hours and then the other side died. Instead of another new board, I bought all new caps, diodes, and transistors to try and fix this myself. It powered right on and worked for about 15 minutes before the fan stopped.... -
