Well, here's my thoughts.

First, if you are comfortable attempting a fix on your own, then go for it. You can try the "tap" and see if it actually works.

But, if it does not, then go out and get a new AC unit.

But, before doing the attempted self-fix, located the new unit first and make sure you can actually get it, in the event you totally fudge up the old air conditioner and your attempted "fix" does not work.

My opinion.... if it's already broke, then try to fix it myself. If I can fix it, I've saved myself a bunch of money. If I can't fix it and end up breaking it even MORE, well .... I've not lost anything since it was broken to start with.
