I just turn my AC Unit on and the fan outside the house would not move.

I moved with a screwdriver and finally worked, however in the middle of the night it shut off.

I unscrewed the fan to notice that when using my screwdriver the fan grill and the chassis seems to have a current because I can see sparks.

Kind of when a battery cables make wrong contact.

I want to know if that is normal?

Is the chassis of an AC Fan live?

Regards.
