Run Capacitor vs. Start Capacitor: What''s the Difference?
The short answer is no. A run capacitor cannot be used as a start capacitor, and vice versa. This is due to their different electrical characteristics and internal designs. Run capacitors, like the name suggests, are designed to remain in continuous use during the operation of an electric motor or other equipment.

Refrigerator Compressor Not Running
If the capacitor has failed, the compressor will not be able to start and run as it should. Most newer refrigerators use a run capacitor, which stays in the circuit and improves the energy efficiency of the compressor. Some older refrigerators may have a start capacitor, which functions just at startup. These are not as common.
grounding
In this case, the circuitry inside the boxes (and the shield) are floating (i.e. not connected to ground) so no common mode current flows due to ground loops. However the capacitors mean the RFI flowing in the external skin of the coax is still diverted to the metal cases at each end.

How does a run capacitor value affect the motor?
A run capacitor helps a motor run more efficiently, while a start capacitor helps the motor to start up faster (which can save energy). The difference between them is that a run capacitor is constantly engaged in running the compressor, while a start capacitor only engages when the compressor first turns on.

Do capacitors automatically release their energy over time?
Capacitors have ''leakage resistors''; you can picture them as a very high ohmic resistor (mega ohm''s) parallel to the capacitor. When you disconnect a capacitor, it will be discharged via this parasitic resistor. A big capacitor may hold a charge for some time, but I don''t think you will ever get much further than 1 day in ideal circumstances.
