    Outside AC Unit Making BUZZ Noise but Fan not running!
    I noticed that my outside AC unit is making a buzzing noise and the fan is not running. Of course, this is also NOT making the home cooler. Currently, I am running the second AC unit for upstairs and using fans to survive. What can be this problem?

    Maybe a capacitor, A tech May? Try to give fan a push to see if it will start, will use a stick, not finger.

    Hi Stratmando,

    Thanks for the fast reply!

    If there is something wrong with the Capacitor then how much do you think the total cost will be to fix it?

    Thanks,
    Azam

    If it is a quiet buzzing, sounds like both your fan and compresser are not running. Check your voltage to unit, fuse/breaker if all are fine your fan and compresser are probably hot and comp. off on overload and fan is probably bad.

    Yep, if very quiet buzzing, you most likley don't have 240v to condenser. The buzzing you hear is the contactor. First check all breakers, disconnects(and fuses). Let us know what you find and we will take the next step.
