To determine if a capacitor in an AC unit is bad, you can visually inspect it for signs of damage, such as bulging, leaking, or corrosion. Additionally, you can test the capacitor with a multimeter set to the capacitance setting; a significantly lower reading than the rated capacitance indicates it may be faulty. If the capacitor is swollen or has a burnt smell, it is likely defective and should be replaced. Always ensure to disconnect power before performing any tests to avoid electrical hazards.
