Kyle,
Have you isolated the buzzing noise ?
If the noise is near the center, bottom, of the unit, That would indicate a bad turntable motor,

Part number: AP2024962
Part number: AP2024962


If the noise is from the upper area, or the control panel, You would have a chattering relay or loose connection on the PCB.

Part number: AP3192717
Part number: AP3192717


The turntable motor is the more likely issue, it's a low voltage motor (21 VAC) and loose connections have a large effect on the motor windings.

Thanks,
:) :) :)

Kyle,

Order and install the new turntable motor(see previous post), and make sure the connections are tight on the new motor assembly.
