MW Oven platter motor direction control

Ive noticed that my motor sturns in either direction arbitrarily when powered.
I tried with a cap to get it in the same but that didn’t work. Is it possible? How?

Turntable motors are unbiased synchronous motors with two wires. Short of modifying the magnetic
poles to be shaded (tricky to say the least given the construction) I don't see how you can effect a
preferred direction.

So You would say its impossible; thats a shame. Anyway, for my present project I modified my code to fit. Thanks.
