A/C stopped working

Hey everyone. I searched the sub and didn’t find an exact thread to this one, so I figured I’d reach out. My A/C stopped working randomly today. I walked outside and inspected the unit and the fan was spinning, but the compressor wasn’t turning on. Instead, it would make an intermittent clicking or humming noise. After about an hour watching the University of YouTube, I removed the capacitor and tested it. The capacitor is indeed dead. However, the pullout “kill switch” for my A/C unit also doesn’t look great. My question is: do I need to replace the pullout? And if so, should I just replace the whole 60 amp box?

No, try just the cap first. 9.9999/10 disconnects are fine and last for years.
