I replaced the drum front support, the glides, the felt drum seal and the light bulb yesterday. Ran a load last night and dryer worked fine - no more squealing! - however, it didn't stop when the (digital) timer hit zero. Tried again today, unplugged and plugged in again, same thing. It does stop when I open the door. Dryer worked fine before I messed with it. Opened electronics panel and I don't see that I loosened or pinched anything. I find it highly unlikely that this is a coincidence and something else went out - it has to be something I did when replacing the other parts. Perhaps when replacing the front panel?? I would be so grateful for any help! thanks for reading this!:o
