Product review (1 stars): The 110V part is cheaper (has the terminal in the center vs off to one side like the 110V part)
I wanted to add my two cents since I appreciate this posting because it has helped me save my fridge and I have done a lot of research since then. The first thing you should do is a continuity check on the three compressor terminals to see if any of the leads are shorted together. If they are then you need to replace the compressor since the transformer windings are shorted. If the compressor is ok then its likely the Overload Heat Protect part which is failing likely because theres a design flaw with the part. I was able to remove mine then reinsert it to get the freezer to work again though it didn't work well (compressor kept turning on and off and when I replaced it the compressor is staying on). But it gave me enough time to order a new part. The part sells for less than $9 on ebay. Do a search for these part numbers since they will all work for the 110V part: 6750C, 4387913, 2154759, 4357207, 4387766, 4387836, ER4387913, AP3108669, PS371538, SZ4387766, 77600, 586521, AH371538, EA371538. The 110V part is cheaper (has the terminal in the center vs off to one side like the 110V part). Now the 220V part is cheaper (less than $1 each from China) and may work but I was concerned that it could draw less current than the 110V part needs but it could still work so you might want to try it. Do a search for this part number on ebay: R600A. If the Overload part isn't the issue then do a search for QP2-4.7 3 pin or 4 pin and they sell for under $4. In addition I was able to get the manufacturer to send me the two parts since the freezer was still under warranty (it was either that or ship the freezer out which would be a huge shipping fee). Happy hunting!

Update on this. My freezer stopped working 1 week after I replaced the Overload Heat Protect part so I replaced the QP2-4.7 3pin Start Relay and its been weeks and its going strong. I also re-installed my old Overload Heat Protect part that I could shake and it made the shaking noise and it works fine. The diagnoses that a shaky Overload Heat Protect part shows you the part is bad is dead wrong. Its the Start Relay that was replaced which is defective and they are really cheap to buy (likely why the fail so often!).

I actually still had the freezer under warranty but they said I had to ship the freezer to Canada at my expense. I asked them to just send me those to parts and I am still waiting for them..waiting Finally got a reply from them and they said they don't carry the two parts. If this is true, this means they aren't repairing anything. It is a SCAM since the parts are readily available and a huge percentage of their freezers have this defective Start Relay! I called them threatening to raise a class action law suit against them but could tell they aren't going to do anything because this is what the lady said. If anyone does sue them, count me in..
