    motor start capacitor

    Posted by Bill Strange on 20th Aug 2020 1:19

    compressor motor was just buzzing when under a load, thought it might be the motor start capacitor. after installing. the motor did the same thing. Maybe there's something else wrong. Don't know, it just suddenly started doing that and the first thing i thought of was the starter capacitor. don't know how to test it but it still looks like a brand new one even though it's around 30 years old.
