refrigerator is not cooling at all but the compressor is running
I checked for 120v to the compressor and i can hear the Evaporator Fan

It should have an even frost pattern across the the whole evaporator. If you have a thermostat or lazor thermometer the coil temperature should be -15 degrees to -20 degrees. If it is not that temperature on the top an bottom of the coil you have a sealed system leak. 95% chance its in the evaporator. In that case you would need to replace the evaporator. I have attached a video link for a evaporator replacement and we have several more on our website.

Are you are positive the compressor is running, these compressors are very quiet. If the compressor is definitely running the next step would be to remove the evaporator cover to examine the frost pattern on the evaporator. There is a link below to click to show you the freezer cover assembly and how it comes off. Once you remove the cover you should have a light even frost pattern across the evaporator . If you have frost on the cover and heavy frost build up on the evaporator this is telling us you have a part of your defrost system defective. So hear is an overview once you get the evaporator cover off.
1) Heavy frost build up – Part of defrost system is defective -email me for next step.
2) While unit is running and no frost on coil – This means a leak in system or weak suction valve in compressor.
3) Half the coil frosted and half not – low refrigerant charge leak in system most likely evaporator.
If your problem is number ( 1) it is cost effective to repair . If its 2-3 it is very expensive to replace the evaporator or compressor. Let me know what you find.

Hello
If you have 120 volts at the compressor you have two possibilities.
1) You have a defective compressor starting components at the compressor. The components you will need are a starter relay and run capacitor. I have provided part numbers and links below for both parts.
2) You have a compressor that is tied up or locked up and that is called ( LRA ) locked rotor Amprege. If you have an meter to check amprege the average running amprege functioning properly should be .4 to .7 amps. If your amprege is 1.0 or higher you have a defective compressor. If you do not have a amp probe you can try the relay and run capacitor. They are under $60.00 for both parts.
Thanks Matt Ace technician

But I can hear the compressor run

If your compressor is running then you most likely have a sealed system issue. I have found out in the field that leaks are very common on these units. Look at the evaporator. DO you have an even frost patter? Heavy frost build up at top of evap but no frost on the rest of the evap, or dripping water? Theses are all signs of a refrigerant leak. Typically it will progressively get worse as far as cooling and freezing goes until it gets to this point where it will not cool at all. Unless some one did something to the unit like move it to cause a large leak. There are some stop leak products out there if the leak is small enough and you can recharge the system. It can be difficult to find and repair small leaks. The most common place is in the evaporator but it is usually not cost effective for this repair.

The compressor is running at .5 amp and evap has on frost its dripping water from the top
