I don't live in an area where brown recluses even exist, but I was under the impression they were kinda rare; are you sure it's a brown recluse and not just a normal brown spider? Where I live, people always freak out and think everything is a black widow (when it's in fact, say, a wolf spider, which looks absolutely nothing like a black widow), but I'm getting off track. Sorry.
If you have bug spray, spray it all around the microwave then try to spray under it. Keep at a good distance. Remember that you can always wipe up the poison later, so it's not bad to lay it down thick.
If no bug spray, use a sponge (or toilet scrubber for extra reach without getting your hand near spider) to apply a thick, goopy line of soap (like hand soap or body wash or something) around the microwave, then try and flush the bug out with soapy water and mash it/let it die in the soap.
Powdered bleach isn't a bad idea to use as a perimeter, except be sure to clean it up unless you want bleach in your food. I think it causes blindness and death if ingested. Bleach in general is very bad for stuff that's alive, so a spray bottle of it (some liquid form of bleach, I don't think powder'd work in a spray bottle) could make a bug spray substitute.
It's 4 in the morning, so I'm probably as much help as those fire guys above... good luck.
