Avanti wine cooler temperature problem

If your Avanti WCR683DZD-2 wine cooler's LED panel is blinking when plugged in and neither the fan nor the compressor comes on, there could be a few potential issues. Here are some steps you can take to begin troubleshooting and attempting to repair the unit:

1. Check power supply: Ensure that the wine cooler is receiving power by verifying that the outlet is functioning correctly. Try plugging in another device to confirm if the outlet is working properly.
2. Inspect the power cord: Examine the power cord for any signs of damage or wear. Make sure it is securely plugged into the wine cooler and the power outlet.
3. Check the control board: The blinking LED panel suggests a possible issue with the control board. Inspect the control board for any visible signs of damage, such as burnt components or loose connections. If you are knowledgeable about electronics, you can attempt to repair or replace the control board. Otherwise, it may be best to consult a professional technician or contact Avanti for further assistance.
4. Test the temperature control thermostat: The thermostat controls the operation of the fan and compressor. Using a multimeter, you can check the continuity of the thermostat to determine if it is functioning correctly. If it is faulty, it may need to be replaced.
5. Examine the compressor: Inspect the compressor for any visible issues, such as loose connections or damaged wires. Ensure that it is receiving power and that the compressor motor is not overheating. If the compressor is not running, it may require professional servicing or replacement.

It should be a compressor fault, let me check

You need a dual zone wine cooler. They have two temperature controls and the storage space is divided in such a way that each temperature control has its own section inside the cooler; allowing you to store both red and white wines properly.

same problem, can not fix. Had a authorized service tech who said that you can not add freon to this unit, the only option is to plant flowers in it.

This is easy. It's the power supply problem. I bet you there is no juice coming out of the same electrical plug. So fix the plug or reset the circuit breaker.

I have the same E4 problem. You can order the PCB from Avanti at Miami Florida or your regional Avanti service rep.

check if you get power by the motor if no power change the thermostat

All the wine chiller set 2 temp red and white, red wine temp only for 18- 20 oC , your using white wine don't set red wine temp , set only for white temp mode,white and red wine set temp are different temp

I don't think you'll be able to do this without some modifications to the unit.  The wine cooler is designed to blow cold air into the bottom section, and the top section cools down by spillover of cool air flowing between the glass door and the temperature control panel.  
I guess if you could figure out a way to turn the panel that separates the top from the bottom you could make it work.  You'd have to switch the temperature sensing leads on the thermostat inside that panel(that would be pretty easy) and you'd probably want to flip the LED indicators so they read right-side-up.  The main issue would be that the screw holes for mounting that separator panel are all on the bottom, but when you flipped it, they would be on top with no holes in the walls to screw them into.  If you are willing to do that, you might be able to make it work as you would like.
Good Luck!
