Only let it run just long enough to hear the hum. Perform a continuity test. Capacitors help power the compressor, the blower motor and the outside fan. Since your capacitor acts like a battery and holds the charge necessary for the blower motor to run properly, it should always stay in peak condition at all times. If the container is cracked or leaking, it is bad. Looking at the capacitor can also give you some idea if it’s a problem. They’re also the only type of capacitor that is polarized, meaning that they will only work when wired in a particular orientation.
