How do I check if a capacitor is bad?

 The physical signs of a bad capacitor are swelling, leaking, or burns, but it may still be bad without the physical signs. Capacitors have a mfd rating that is tested with a meter. If when the capacitor is tested with the meter and the rating is out of range the capacitor is bad.
