Privat reserve cooler...Thermo does not

Cuisinart Privat reserve wine cooler...Thermo does not work. Fan runs constantly and heat sink will not get down to 53 . Many, many complaints on line about the same thing. The unit does not have a refrig, it has two fans that run over a heat sink. Any suggestions. It runs all the time. Was advertised as quiet. LOL

    Thanks. I have a wine cellar in the basement. This unit is sold as a solution for the kitchen. Not to stick in the basement. To hold a few bottles in proximity to the area where you entertain. So ambient below 70 is not in line with their own advertising..

    Hah! .So whats new in 2008 in America along with all the the other toxic **** we bring to market. Why should I be surprised.LOL.

It might be several reasons for that:
1. Ambient temperature is too high. It should be below 70 F, that is why it should be installed for instance in a basement. Kitchen might be too hot. If temperture is 75 F this unit will never go to 50F
2. Do you have a lot of moisture condensed inside (some moisture is allowed but not too much). If yes there is a leake from outside. For instance door seal. Once the system is not closed it keeps operate to set the temperature.
3. The unit might be obstructed. It should be some free space around, no heat generating applience (fridge, oven etc)
Good Luck

Check if there is dust on the coil behind the fridge and clean it.

If there is ice on the coil do a defrost, leave space between fridge and wall behind, the condenser is probably under stress because the evapourator system is inefficient.

My Cuisinart cwc-600 does not cool. It registers 45 degrees but is not cold enough to make white wine palatable. No matter where it is set, it seems to be a room temperature. We live in a small house so...


I have been all through these, and they are not very repair friendly. If it's under 3 years old Call Cuisinart, they will exchange it.

They are solid state cooled using a peltier chip cooler. There are 2 fans in the back cavity, and 1 inside. Remove everything from inside, and set the temp to cooling. Do all 3 fans run? If the inside fan does not run, no cooling. The fans are common 2 wire 12 volt computer fans, and available at computer parts stores that sell PC cases and components. Next is to check the cooler itself. Remove the inside rear cover. There's heatsink under the inside fan. Does it get cold when the fridge is running? If not, the next step you will need to get the back off. The Torx screws are special, but a quick slotting of the screw heads with a dremel or a hacksaw, and a regular screwdriver will remove them. Once off, note the red/black fan wires. Also see if there is a load of dirt in the heat sink. If it's plugged, no cooling. Back to the red/black wires. The fan wires are thin. The peltier cooler is heavier. Set to cool, Check for 12 volts on all 3 pairs of wires. If there's power, the fans run (inside and out) and the inside heat sink does not cool, the peltier chip is bad. It's major surgery to replace the cip, but it can be done, and there are scads of sellers on E-bay selling 60-90 watt peltier coolers that will work. They are standard millimeter square sizes, just match the thickness, 12-15 volts, and wattage (around 60-90).

If you are not getting power on the peltier cooler chip lines, there is a tiny fuse on the lower left of the circuit board. Check it.

These are not servicable from cuisinart. Even the silly screws to change the light bulb are security torx type. Fans are available at computer parts stores. Fuses at electronic supplies. The peltier chip can be had from E-bay. That circuit board is impossible to get. Any other parts are impossible to get to by the way it's built.

Stopped working. There does not seem to be any fuse to change. It is just dead.


The fuse is on the circuit board inside the back, located near the AC power connector. You will need security Torx bits to remove the screws. It's a metric 2.5 ampere fuse. However, chances are the fuse blowing is a sign that the little fridge has a bad circuit board, usually blown out by dust collecting on the outer heat sink causing overheating, the fans not turning anymore, or a voltage spike shorting out the switching power supply input diodes. This is a common problem with these. Finding a new board from Cuisinart is the solution.

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.

CWC 600 was working fine but now it is off completely. Is there a fuse of a power switch that can be replaced. We had some wind and rain that made our power go on and off several times within a short...


These CWC fridges have a switching power supply in them that is very voltage spike sensitive, and they blow easily. There is a metric 2.5 amp fuse on the circuit board that protects the board. The next components are 4 rectifier diodes that short out with voltage spikes killing the board. Changing the fuse usually does not fix it. You will probably need a board. Heat kills them too, so if you change the board, remove the fans and vacuum all the dirt off the heat sink as well.

Wont cool down fans in the back of the unit constantly run


Remove the back.
Remove the fans. See of the heat sink is not plugged up with dust. If so vacuum it out.
Get a dc voltmeter. Fire up the fridge. Set it to cool. With the fans running, check for 12 volts on the connector that's on the lower left of the circuit board. This connector powers the Peltier cooling chip. If you have 12 volts, and no cooling the Peltier cooling chip is bad, ir the second fuse is out. There is a small cylindrical fuse near the lower left corner of the circuit board. Carefully check for voltage across it. If the fuse is good, and the fans running, you will not sense voltage across this fuse. Bad, you will read ~12-16 volts.

If your Peltier Chip is bad, it's usually caused by over heating from a plugged up heat sink or fan stoppage. These chips are available off E-bay for ~$13, but require nearly a total tear down of the fridge to change it. 95% of these cooler chips are single layer, square, and vary in thickness. You should find one that is drop-in should you choose to 'Go for it'. Look for a 60-80 watt unit that is the same or slightly thicker, and the same size square.

Cuisinart Private Reserve cwc-900 wine cellar stopped cooling


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.
