Dryer won't start, makes loud noise as if drum is stuck. I suspect belt or pully, but am having trouble accessing drum, can't open top of dryer. Is there another access from the back or am I missing something to remove top. Thank you for any help.

Thanks Glen, I tried what you said, the drum turned free counter clockwise, but not clockwise. The motor would "buzz" as if under load when I turned to Start. Drum didn't catch and start while turning counter clokwise. Motor stopped buzzing, (I only kept start switch on 3-4 seconds) but would buzz again after trying a few more times. I removed the small panel in the back and could see the motor and idler pully, belt is intact. I guess it may be the motor or bearings? Is the top of this model supposed to open like most others? I didn't want to force it and I don't see any screw holding it down. Thanks.
