The short answer to this is “no,” but we promise to elaborate.
Essentially, trying to scrape ice off of your air conditioner yourself could end up further damaging it, plus removing the ice doesn’t solve the problem that caused the ice buildup to begin with!
So, what does cause that ice buildup? It’s not a normal occurrence, despite your air conditioner cooling the air. We understand how it could be easy to believe that ice might be involved, but transferring heat from one place to another using refrigerant as an air conditioner does, does not use ice, and shouldn’t create it either.
