i have an Admiral super Capacity 5 Cycle Dryer, Model # ADE7005AYW. It still dries clothes and all buttons work, however, it is making a screeching or loud scraping noise and so I am not currently using it. I tried to take the back panel off to look inside, but there is no back panel!!! the back is all one piece and connected to the front body. the top of the dryer seems to lift off but I don't seem to be able to get to anything from there. HELP!
