It should say on the compressor and the fan motor labels.
capacitor on the condencer unit nothin will work
Either mounted to the fan or in the electrical compartment on the outdoor unit.
Typically a bad capacitor is a sign of a weakening Compressor in the unit. Rule of thumb: If the unit is 20+ years old, you would be putting a band aid on it by replacing the capacitor. If you decide to try and get by with an older system for a few more seasons, I recommend to put a new capacitor on the unit with a hard start system installed on the compressor. You can normally have this done for under $300.00. And back to your question; capacitors are sized depending on the size of the unit. Check your tonage of the unit and bring the capacitor with the correct tonage to a Parts house and they will make sure it is properly sized. Hope this helps.
Capacitors are measured in Farads or microfarads.

Bad fan motor or bad capacitor.
Yes it can. If the fan is not coming on you could have a bad fan motor, a bad capacitor, a loose wire at the contactor, or a loose wire at the capacitor.
