Turn table won't turn

Hi there, my turn table won’t turn at all. We looked at the piece underneath the plate and it is not cracked but I can pull it up as it’s loose, not sure if this is normal. How can we get it to turn? Thanks.

Hi.

If you checked the coupler and it’s OK then open the bottom cover and locate the turn table motor AP2024962

Take the two wires off it and use the voltmeter to check for 21VAC across the wires with the MW turned on.
If the correct power is present - replace the motor, if not - replace the control board AP3418930
