Avanti wine cooler is clicking - Magic Chef MCWC30MCG Compact Wine Cooler

The above has a troubleshooting matrix.

Power supply: Check if the wine fridge is receiving power from the mains supply. If it's not, there might be a major issue with the mains power or the PSU circuit board in the product that'll likely need replacing if it's faulty.
Condenser fan: The condenser fan is designed to cool the condenser and condenser coil within the Avanti wine cooler. If it doesn't function, the condenser and coil can overheat - causing the internal area of the wine fridge to heat up too. Take a look at the rear of the unit and make sure the condenser fan is spinning freely and not blocked (by dust / dirt) or making excessive noise due debris or a blockage.
Thermostat: If the Avanti wine fridge thermostat is working correctly, it's responsible for making the condenser, evaporator, fan, and compressor work - so it's super important! The thermostat also allows you to control and adjust the temperature of the wine cooler so if the reading on thermostat is inaccurate (or flat out wrong) the wine cooler temperature will likely be inaccurate too.

Why Is My Avanti Wine Fridge Not Cooling (And How To Fix It) - Expert Wine Storage

I've added a link for an Avanti ewcb,
http://www.retrevo.com/support/Avanti-EWC16B-Refrigerators-manual/id/867bh235/t/2/. There you can find a complete manual on the product which will help you to locate where the problem is coming from. hope I've helped!

if you are handy go to a refrigeration supply hoese and buy a 3-1 pack remove the wires from the compressor let it cool if hot and hook to 120 volts wiring it shows you on the package..........luck

The issue could be the cold control, timer, wiring, or the compressor.

The temp control has to be closed for voltage to get to the timer. The timer then calls for the fans and compressor to run. The timer could have stalled after a defrost cycle or the cold control could not be sending voltage to the timer.

either the electronic control is bad, or there is a temp-hold button somewhere on it

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.

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

the wine cooler has to be at least 3" away from the wall, do not block the air flow to the condenser. or check power plug to outlet is it secure.

pull it out and lay hands on the compressor and see if its running if not replace the thermostat
