I have an RB-22J1A Durabrand wine cooler. After a power surge, it quit cooling. I disassembled it and discovered it was cooled by a die-electric device. After checking the board with my VOM, I found the board put out the required 12 volts. Although the die electric coil reads continuity on my meter, it does not develop any temperature differential upon energizing. I probable need a new die electric device, but am having trouble finding this part. Can you help??
I bought 2 of these wine coolers and both of them ****! You would be better off returning it if you can or putting it in the trash.Both of mine did not keep them cool. At first they worked for about a day and then they stopped. They refrigerate around 70 to 76 degrees and stay there.

Small refrigeration units like this one like to fail to cool by developing a small leak and slowly leaking refrigerant. THERMOSTAT FAILURE CHECK: A technician will check the thermostat using using a DMM (digital multimeter). But you can suspect the thermostat if you set the thermostat high and the compressor motor does not run, then set thermostat low, and the compressor motor also doesn't run - in other words, the thermostat is failing to start the refrigerator's refrigeration system no matter what its setting - an obvious failure of the thermostat. COMPRESSOR FAILURE CHECK: If the compressor is dying, you would hear the compressor running almost constantly, but not sounding quite right (uneven noise, clunking, tapping). REFRIGERANT LEAK CHECK: If you unit is low on refrigerant (due to a leak), the compressor motor will be running almost constantly, but it will sound Ok.
Sounds like the cooling unit, i.e. heat sink and controller chip. $35 + $10 shipping from vinotemp, and you install yourself. I'm looking at the same thing (on the 28TEDS), though mine came after having to replace (for $45 and my own installation, incl. soldering) the circuit board. I hope yours doesn't go, too. I've read of others. Pretty poor quality parts they appear to use. I'm trying to find somewhere to buy the controller chip on its own, as the heat sink is simply a hunk of metal. Hopefully that's do-able, as it is with computer cpu's. See: http://www.vinotemp.com/Browse.aspx/446/Replacement-Parts
usually bad power supply, if the cooling fan isn't running either. These are horribly inefficient coolers that use a lot of power to accomplish little cooling. The power supplies are quite notorious to burn up.
If your supply is 12vdc output, you might be able to replace it with a supply from radio shack. dont use a battery charger though.
