Thank you very much for the detailed explanation, makes complete sense! I poked my head inside of the drum and couldn't find where the light lense goes (I'm hopeful you can provide insight on this, and that it will just snap back into place). The funny thing is that I don't recall ever seeing a light within my dryer, so I'm guessing the bulb has always been burned out. Is this a hardware store item or do I need to buy it from an appliance website? I also just noticed the 2nd snap ring you speak of, and it looks like it's in great shape (has a nice silver color to it). The broken snap ring was very rusted for some reason. I'm tempted to replace the "good" snap ring anyway as it's <$2, and I don't want to do this job again lol. The center of the blower wheel looks more like a circle than a D, so yeah, guessing it's just flat-out worn out =P.
