Cooler won't cool. Fan is running, compressor seems to be running. No cool air is coming from the fan.

Condenser fan motor or motor wiring is bad. That compressor should never run without the fan. Good luck.

If you hear a clicking noise coming from the compressor there is about a 80% chance that the compressor is dead. But you'll have to call someone out to be sure.
If the fan motor behind the grill is running (condenser fan) then the compressor should be running and vice versa. If the compressor is hot as a pistol and clicking and the fan motor is not working then it may cool down if you shut it off and you might just have a bad fan motor. With power turned off the condenser fan motor should freely spin. Compressor have a 5 year warranty from the manufacture not including labor and additional materials. Hope this helps.

The compressor is running, that is a good sign. If you notice any cooling that is not a good sign. Even with the fan not running , the evaporator should have produce some cooling. Could it be that you are a condenser fan running? well, the compressor makes a distinct sound when it runs and you need to confirm that is running and not just the condenser fan.
Firstly- If you confirm that the condenser fan is running; that is, if there is one, that is good. Secondly- Check and confirm that the compressor is running Thirdly- If there is an evaporator fan inside the unit, check and confirm that is running.
If all checks okay and there is no cooling, the refrigerant might have escaped through a leak, and there will not be any cooling. You can extrapolate from my troubleshooting steps to diagnose the wine cooler problem.
Good luck

That is a broad question. Lets do a checklist. When you plug the unit in the compressor behind the grill on the front should come on and the fan in front of the compressor should come on. The radiator in the compressor compartment needs to be clean from all dust and grease. Many times this is overlooked and can cause real problems by letting the compressor overheat. Now look inside and find the fan cover. It hangs from the inside top of the cooler. It should also be running. If either fan is not running the unit will not cool. Sometimes there is an obstruction, such as someone pushing a six pack up against the fan cover and pushing it into the fan. The fan down by the compressor is sometimes blocked by the cardboard shroud that is built around the fan. Also in a few cases rodents have gotten caught in that fan. If everything is running, you will have to look deeper into the compressor compartment. There is a screw in the front of the radiator that hold the compressor unit in the cooler. Unplug the unit from the wall. Remove that screw and slowly and carefully pull the compressor unit towards the front of the beer box. It will slide almost all the way out. You will see a coil of copper tubing at the back of the compressor that allows enough slack in the lines to slide this unit out. When you push this unit back in it helps to have someone behind the cooler to pull back on that coil as you push the unit back into the machine so it does not get crimped. With the compressor unit pulled out, plug it back in at the wall. If your compressor is running and you have proper amount of refrigerant, the small copper tube from the compressor to the radiator will get very hot, enough to burn your finger, after two or three minutes. After 10 minutes the larger copper line that is usually enclosed in a rubber sheathing should get cold. One way to know if you have a burned out compressor is to listen to the compressor and fans when you first plug into the power outlet. A bad compressor will usually try to start for 2 or 3 seconds and then click out. While it is trying to start the fan will slow down because the compressor is pulling way too many amps and is pulling power away from the fan until it clicks out again. If you can hear the compressor come on and run but it makes no heat to the radiator, you probably have a refrigerant leak. Your freon is gone or almost gone. If it was a slow leak you would usually notice that the cooler does not seem to cool like it once did. If it was working good and suddenly stopped cooling, the most likely problem is a bad compressor. Changing a compressor is usually beyond the average do it yourselfer because it requires welding the unit in place and gauges and a supply of refrigerant which is almost impossible to get without a liscense. Let me know what you find out.

The compressor may not be starting. Put your forehead against the nmachine when youturn it on or plug it in, You will feel the vibration of the pump. If it is not coming on, you may need a technician to what determine why it is not working.

sounds like the blowers capacitor has gone bad

check condenser fan if running. it will make compressor comes on and off if broken

check for bound motor

This appears that you probably have a serious leak in the system. You will need to find this leak repair it. Then recharge the system.

Hope this helps You

Have someone check the run capacitor of this unit. If the run capacitor is bad over shorted it can cause the unit to run and short cycle on a current overdraw. This makes for an electrical imbalance in the compressor motor. Next step is the compressor is faulty.
