AC outside unit

Hello, I was running the AC in my house for the past few days, yesterday I try to turn it on and it didn't, I went outside and I heard a buzzing noise in it. Any suggestions?

Thank you.

Sounds like the contactor problem, but we need more info to be sure. did you open the condenser panel to check it ?

I checked the breakers, breakers are good,checked the two fuses, they are good, where and what am I checking at the condenser panel?, when I turned it on it wasn't a constant buzzing, I heard a click and then like it wanted to start, I moved the fan blades with a stick and they moved freely.

do you have a volt meter and know how to use it? Remove the panel and verify the contactor is pulled in with a call for cooling. Check the capacitor for swelling.

I do have a volt meter, I don't understand what you mean when you say to verify if the contactor is pulled in, may you please elaborate. Thank you

Google contactor and you'll see what I'm talking about when you see it in your unit.

The capasitor is swollen, I checked the voltage in the contactor and it read 240 V. If it is the capasitor, is there a place that you recommend to buy it?

go to a local motor shop or buy it online, it does not matter. A capacitor is a capacitor and they are common. Average cost is $30 - 50 retail.
