so here's a dumb problem i have:
i removed the top/fan assembly of my AC unit to clean inside as well as one of the side panels (before realizing i could vacuum through the panels just fine).
when reassembling, i just can't get the screw holes in the top to align with the screws on the sides. with great effort it seated properly onto the sides as far as i can tell and there's not any wiggle, but i'm like half a centimeter off being able to get a screw in.
what should i do? it feels solid without the screws and sounds fine when i run it, so i'm tempted to just forget about the problem. another alternative could be drilling new holes where the top sits now. or i could call a professional but it feels a little ridiculous. advice welcome
