These capacitors are designed to break the circuit in case of overheating which leads to swelling and bulging, if you see that it is bad.
Simple first test is clamp on AC amp meter on one capacitor lead. If no current probably the capacitor is open which is the most common failure (but it could also be open motor, broken wire somewhere, or lack of power to the entire circuit, presumably you have checked those). If current on the order of amps is measured, disconnect capacitor and check it for shorts.
