BEFORE you pitch the yeast? What got it down to 1.012? Are you talking about future batches? If so, you can do that but understand that your gravity will be lower and will make for a weaker beer. You'll dilute flavor as well. It depends on what you're aiming for. A nice session beer might be okay, but a heavier stout would suffer.
If you can't fix it with a hammer, you've got an electrical problem.
