Cuisinart Private Reserve cwc-900 wine cellar stopped cooling

I have a Cuisinart Private Reserve cwc-900 wine cellar, which has stopped cooling. It has a Thermoelectic compressor-less cooling system, which looks like a little square plate sandwiched between to heat sinks, one small and one large on the exterior. It looks like some fluid has drained from this apparatus but I don?t know from witch part. I have disassembled it and the square plate (part # tec1-127-08) was covered with white stuff that resembles wet paint. The plate still gets hot. Does anybody know what I need to do to fix this and would it be worth my time?
Thanx
Bryan

    Thanks, There is hardly any compound left and the works but seems slow, I'll change the fan and put more compound on the square plate.

    Hello Fritter.

    How did you get the unit apart?

    Thanks.

    My unit is not cooling either and I hear a fan runnig but I can't get it apart to see if the heat sink plate is getting hot. Whatdo I need to do to check it.

    I too have this wine cellar. Wish I would have kept the documentation/warranty. I've had it for 1 year and 5 months. Hopefully my computer building skills are good enough to fix this.

    Dear Fritter, I had exactly the same problem you had! Did you solve yours?

    Mine stopped cooling as well. The serial number label is horrible. They put it on there with several wrinkles. Fortunately I was still able to read it. I received it as a wedding gift almost two years ago. Now the thing is a hunk of junk.

I also had one of these CWC 900 units that quit working. The interior temp was 77deg F and the outside was 70 deg F.
The exterior panel was very warm to the touch where the heat exchanger was.

Like a previous person stated, there are two fans. One on the control unit board and then the main cooling fan for the exchanger. In my case, this main cooling fan had quit working - allowing excess heat to build up.

Solution: Unplug the unit! Remove the side panel of the CWC 900. First remove the 8 "finishing" plastic plugs that hide the screws. This was done with a sharp point on an ice pick to pry them out. Then remove the 8 screws with a torx T10 driver. At this point, plug the unit in and lower the temperature setting. In my case the small fan kicked on and the larger one did not. Un plug the unit. If you try and manually turn the fa you will feel resistance. Remove the cooling fan and black housing w/ 4 phillips screws. seperate the wires from the cable ties and then unplug the fan - you may have to remove a small amount of a plastic type glue to unplug the fan. Remove the fan from the plastic housing w/ 2 phillips screws. This is a fan made in China and I was unable to find a replacement on the web. Remove the center sticker on the back with the fan model number. Remove the center black plastic plug with a sharp point. You will now see the end of the shaft and a small split keeper ring. This ring is made of plastic - be gentle. Pry it open and remove it from the shaft (KEEP IT). Once the keeper is removed, you will be able to pull and seperate the motor from the fan blade and expose the shaft. I was not able to remove the small bearing from the motor so I wipe the shaft clean, applied white lithium grease and the re-assembled the unit. Fan spun freely. Put everything back together and the unit should be fixed!

Hoped this helped.

    Thanks cajun! We picked up a cwc 1600 for $20 at a resale shop. We got it home and discovered although it "ran" it wasn't cooling.. we followed these instructions and now its working great... we didn't have grease though, so we used a

Finally, after about 5 months of a non-working unit, I believe I have got this cwc-600 up and running again. Many of the cwc-900 owners spoke of 2 fans but this unit has 3. I believe that translates to 2 cooling fans (located in the back of the unit) and 1 blower fan (located inside). My problem was with the fan inside which was not functioning at all and resulted in a higher inside temperature than that in the room.
To fix this I used the following:
1) Phillips screwdriver
2) Vegetable Oil (didn't have anything else on hand)

Working from inside the unit, I unscrewed 4 smaller screws from the inside-back. This released the fan shield in which the fan was attached to the center with 4 larger screws. I sprayed compressed air on the fan and spun it around a bit. After plugging it in I noticed that the fan began to spin again. After unplugging it again, I doused the fan with vegetable oil in hopes that it would reach the inner axel. After reassembling, it seems to be spinning freely, and hopefully I can enjoy properly cooled red wine again.

    Update to my last post. The vegetable oil fix didn't last long (something like a month). I've since ditched the unit.

I had a similar issue with mine, and pulled it apart (drilled out the plugs, and used a torx screwdriver). There are two fans. One cools the control unit, and one is a blower on the heat exchanger cooler. The blower fan had seized up (it had some dust binding up the bearing). Unfortunately, I busted the motor trying to clean it. Putting a house fan on the heat sink while the unit was apart demonstrated that it still worked fine. I am going to try installing a cheap computer heat sink fan to see if I can fix it with a $20 fan from Radio Shack.

I haven't seen the unit you refer too but it sounds like many others that I have seen. The white stuff is heat transfer compound as used on CPU heat sinks, DO NOT WIPE IT CLEAN, if you have then it will need replacing. Check the fan is running at full speed to cool the heat sink that the plate is attached to. If there is no fan then there isnt much else that can be wrong with it apart from the control circuit, but that seems to be working as you say the plate gets hot.

My power supply keep on blowing fuse. I tried replacing fuse twice and immediately blown when plugin power. What could be the reason?


A dead short is more than likely. Potentially a shorted out compressor or wire pinched or a bad control board. I'd check the compressor terminals to ground, any motors to ground. With and without the wires hooked up to them. If the compressor or fan motors are grounded out it could cause that symptom. If you test them with the wires hooked up it will tell you if the wiring is shorted to ground.

Wine cooler displays temperature setting but does not run or cool wine.


It's 1 of 3 things...

A. The fans are not turning. Remove the back, and see if the fans are getting 12 volts, and spinning freely. Remove them and clean off the dust from the heat sink.
B. The Peltier Chip is shot. If the fans run, check for 12 volts on the power connector that's on thelower left of the curcuit board. If there's power, but no cooling, the Peltier is shot. These are available from E-bay for ~$13, but it's a major dissassembly to get it out.
C. If you don't get 12 volts to the fans or the Peltier chip, replace the circuit board.

6 bottle unit model cwc-600 died after 6 months. Acts like it isn't plugged in or a blown fuse. But no fuse!


The fuse is on the circuit board, behind the rear cover. It's a 2.5 ampere metric fuse. These boards are very voltage spike sensitive, and chances are you need a new board, as the rectifier diodes in the switching power supply blow and short out easily. If you get a new board, use a voltage spike power strip to protect it.
