I really like the Danby wine coolers, they are usually nice products. As far as your problem, I would first try to find out where the main problem area is. To do that first make sure that your compressor is running. If the compressor is running and it is not cooling then you may have a freon charge issue. Thats not to say that you can just put some more freon in and it is fixed, You would have a leak in your sealed system and you would most likely still have warranty coverage for that. Most Danby products carry a 5 year sealed system warranty. That would include your compressor.
If the compressor is not running then you would know that you have a compressor issue. Either the relay overload on the compressor would need to be replaced or the compressor itself was bad. You can buy relay kits for about $30.00 and intall them easily with very little experiance.
Next if the compressor is doing its thing and trying to cool you could have a fan not blowing air properly. either a condenser or evaporator fan may have stopped. If you find one not working then chances are you just need a fan. If the fans are blowing and the compressor is working then you would just have a defrost problem. In that case you would just need to defrost then check for bad parts, either a defrost heater, defrost thermostat or a defrost timer. Most of the Danby products have a defrost control board, that board willl contorl the defrost, the temperature, and the fans. If the board was cheap I would say just put one on and see if it fixed the problem, but they are around $145.00.
The most important thing for you would be to make sure you are not going to do something that would void your warranty. Free service is always the best. Good luck to you and send some wine my way, I make lots of different types. from grapes, strawberrys, muskedyne, etc.... [email protected]
