The run capacitor, with new crimp wire connectors, is attached to the compressor and is 250 volts. It helps the compressor kick on and off while maintaining a constant temperature to keep things frozen in your freezer. If your refrigerator is too warm, will not start, or your freezer section is to warm, you may need to replace this part. This is a genuine OEM part. Please remember to disconnect power to your refrigerator before starting your repair.
