Wally Thanks. Now I know why I couldn't see how the box was screwed together! I never considered the screws might be under the formica. I'm not ready to re-do formica so cans of insulation will have to do. I like the idea of running the wire for a fan now. It could go to the same breaker as the compressor or could run off the compressor's line.
