Thanks to all for the info. My dad didn't have much of a chance to look at it -- and he lives too far away to really get it taken care of. He thought it was really strange there was a 50 amp breaker, too. But he works mostly on really high voltage stuff. Somebody might have had a problem with it before and just thought UPSIZING the amps would do the trick. It's a square D breaker box, so it might be pretty easy to fix, but I don't know if I want to get that involved. It is a rental. We also checked inside the dryer to make sure everything was pulling the proper voltage, and nothing seemed off.

I do have kind of a shady landlord, so he's not gonna fix it, I'm sure. The last time I called someone to snake a sink, he brought a plunger, and didn't even fix it. Geez...
