Buzz Sound From HVAC, NOT Working

What is this HVAC make/model as the sticker has lost color and is now white. The house was built around the year 2002 so the HVAC should be from around that time.

The Problem: No cool air upstairs (this is the upstairs unit, the other unit for downstairs is cooling and is newer).

Checked this HVAC unit outside (the gray one pictured) and there is a buzzing sound and the fan area above the unit is hot to touch. If the piece is taken out of the shut off switch and left out for several minutes, then upon putting it back in there is a sound like the unit wants to start but it does not.

The picture with numbers and text is of fan's sticker, maybe it helps with identifying the unit. Also a picture of the compressor and its wiring for the same reason.

Thank you for your input and help.

Checked a neighbor's unit and found the HVAC make and model:
Brand:
York

Model:
H2RA030S06D

Product:
Heat Pump

One puzzling thing is if the a/c circuit breakers at the fuse box are shut off the buzzing noise WON'T go away. The buzzing noise only goes away if the sliding connector at the shut off switch near the HVAC unit is taken out. What is going on?

It could be a bad capacitor as there was another unit in another house some time ago that had a bad capacitor. It is getting dark here so I can't go out and check the unit right now, but I did not see an access panel on this HVAC where the capacitor could be. Where is the access panel and the capacitor on this HVAC?

Thank you.

Your pictures are private..... not shared.
You can set them to public or post them here directly...... How-to-insert-pictures.

A buzzing sound from the outside unit can be the contactor or the reversing valve. Either one of these two could make noise and both are powered by 24vAC from the inside furnace or air handler.

I'm far from an HVAC specialist, but I had a similar issue last year with my condenser. It required a new start/run capacitor. Was a nice, easy $8 fix!

Sorry about the pictures, I made them public so the links should be fixed.
Since the posting the access cover was removed and the capacitor was found to have bulged so trying to get a new capacitor and that should fix it. Will report back once a new capacitor is installed.
