Hi, I have a fairly new Whirlpool dryer, model LER7620LG0 that emits a buzzing sound when started. The drum does not rotate, but will if you manually give it a start, then it will slowly revolve. I disassembled the dryer and after inspection the motor has debris around the output shaft bearing (small dark specks, don't know if its magnetic-ferrous). I'm tempted to replace the motor, belt and tensioner but wanted to ask on this forum if there is a possiblity of the motor not recieving both legs of the 220v input (controller problem). I don't have a wiring diagram in front of me, would somebody have one they could post?

Thanks in advance, Dennis Baccus
