My turn table won't turn, I have cleaned the entire fixture

bring it back

Avantiums are heavy. Underneath the turn table mechanically is only the turn table motor and the frame of the microwave. I would let it sit for a day and dry out before using it. But in the long run it might create corrosion and eventually you will need to replace your turn table motor. But I have seen liquid spilled into the turn table motor and be fine. You may create more damage by uninstalling your microwave to clean up the spill.

Is your microwave clean under the table? No stuck on food or anything? Does the the oven work without the table?
Does the little prop in the centre that turns the table move when there is no table on it? Try to carefully clean it and see if that helps.

That would be just a defective secondary interlock (bottom door switch) or its mount.

My help file on door switches is here.

The service manuals you need are here and here.

Almost certain if microwave still heats a bad motor or gear issue inside the unit--if unit will not heat the safety switch in the side that the door engages is the cause of the wheel or platter not turning--prevents unit from use if door open.

Turn table motor itself is defective and making noise replace the same to rectify the problem.

check and see if the turn plate is on correctly

Remove the turn table and clean the rotating circle with the cleaning solvent and the read the instruction manual for avoiding over loading of the table.

Thanks

PLease open the housing of turn table motor at bottom of the oven and check for the AC input voltages on motor terminals as specified on sticker on motor. for no heating please check fuse between high voltage transformer and high voltage capacitor. Also check high voltage Diode and Magnetron.Please please don't try to measure voltage on terminals of magnetron.
