My side by side regrigerator completely stop working

I noticed that everytime I plug the refrigerator cord into to the wall outlet it would trip the shock prevention safety switch on the wall outlet. I came to the conclusion that something was blocking the electrical current to flow to the compressor. I figured if I changed the the part attached to the compressor then the electricity would be able to make a complete circuit to the compressor. so I got the part # from the old part and I researched it through your company. You had the part in stock. I ordered it and it was at my door the next day. It worked extremely well. I proudly can say I did it myself and most importantly I don't need a new refrigerator and I save a lot of money. thanks I will definitely use your company in the future. Ray
