Compressor would not run

Looking at the schematic I found in the back of the unit, it appeared that there were not many parts associated with the problem. I removed the Overload/PTC and run Capacitor as a single unit. Although the capacitor was listed as the most likely problem part I decided to order both items since small particles of non-ferous material were falling out of the Overload/PTS plastic case. I installed both parts as a unit and plugged the refrigerator in. The compressor did not come on so I figured that there were other problems. After about 15 minutes I returned to the unit and found it running. It is now quieter than it has ever been. I now feel that the defective part was the Overload/PTC unit and not the capacitor.
