Re: 8 bottle wine cooler unit won't cool
First, see if the fan is actually blowing anything out of it. YOu may have an obstruction. If not that...Generally, there are three reasons that you won't get cooling:
The condenser radiating fins on the unit are dirty which won't allow cooling air flow to liquify refrigerant. Clean them.
The unit is frozen up inside because of excessive humidity. Defrost the unit by leaving it off and open for a day.
The unit is low on refrigerant. Check this by leaving the unit off for one hour. Locate the pipes coming out of the compressor. Turn the unit on. If the larger pipe stays frosted up for more than 15 minutes, you need to get the unit charged.

I don't mean to sound like a wise guy, but its supposed to! But anyway you didn't mention how often it does this? If its a constant thing then you have a bad contol for the fan and compressor IF it has one.
There is no compressor on these units. These units use a Peltier cold/hot module where the cold side faces the heat sink and the fan exhausts the heat side. Another fan sends the cool side into the frig. I have the same unit, I am experiencing the same issue. I was looking to change out the Peltier modules (about $7 each) and try that. I did find a replacement Control Board is about $45 and if the Peltier change doesn't work this may be my next step.
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.
This is a 6 or 8 bottle free-standing wine cooler from what I can tell.
I am not having much luck determining if this is a manual defrost type unit or not. Given the inital sales price now of $79.95 I have to assume it is a manual defrost type.
There are a few things that can cause your problem.
1. PTC relay and KliXon thermal overload assy on the compressor.
2. Run capacitor
3. Temp control
You said the fan does not run so I cab not rule out the temp control.
I can not even find a parts break down of the unit.
With no fan running the very first suspect is the temp control but you can at least listen for a CLICK when you cycle it from off to any other position. If you hear a click I would start looking at compressor start / run parts.
If you have access to your units compressor note the manufacturer, hp if stated (1/8hp etc) and Model number.
Then call or visit your local appliance parts supply store with that information in hand. The will have a PTC relay / KilXon thermal overload AND run capacitor that will fit your unit. I am pretty sure that will get you going again UNLESS you have a broken wire somewhere.
The replacement parts are going to run about 50% of the cost to replace the whole thing.
