Trane unit humming but not running

I need help with Trane XE 1200. The unit stopped running on the hottest day of the year, it is making a humming sound and every 30 seconds makes a louder hum for a few more seconds, as if its trying to start.

Also, I noticed that the contactors have what appears to be burn from electrical flash all around each contact

No tech can look at it for 2 days, please help

Could be a bad capacitor.

most likely bad capacitor or hard start. IF contacts look that bad, then replace the contactor as a precaution..... doubtful has anything to do with current problem though.
