My Avanit WC54 wine cooler turns on, however it does not cool. Every few minutes it makes a clicking sound

if it is a clicking sound maybe it is a relay. try replacing that

You don't really need the exact parts. Supco sells a RO81_1-12th HP to 1-5thHP that just slips on the compressor S,R and Common pins.

compressor grounded. replace relay or compressor

It sounds like the compressor is locked up. You can unplug the unit, then access the compressor and remove the electrical cover to access the start relay on the compressor. Carefully remove, disconnect wires, and purchase a new one. Replace in reverse order of dis-assembly, and hope the compressor will start again. If not, time to buy a new wine cooler as the cost of repair will probably exceed the cost of a new cooler, unless you are within the 5 year warranty period for the compressor, and even then it will cost for labor and other consumables used to replace the compressor.

A clicking sound every few minutes usually means the compressor is going off on overload when trying to start. This could mean the start parts are bad, or the compressor went bad.

its the ptc relay go to repairclinic.com...type in model #...its a cheap and easy fix.if you see what the part looks like on line youll find it on cooler.should be left of compressor behind black plastic cover with 1 screw

All fridges, freezers, coolers, etc need access ports added to them before any refrigerant can be added to them. Makes you wonder how they do that eh?
