Need help, Back right motor is barely spinning/twitching

[Mikelikesu]

Hello,

I need some help and some advice on what to do. The back right more clicks and twitches. IT barely spins, I replaced the motor and it still did the same thing. What on the motherboard could be causing this?

Thanks!

Also I did an IMU calibration twice and no errors on the screen

If motor is known good then it has to be the ESC or the MC sending the speed command.

Hmm, is there any way to fix the ESC? Or do you just have to replace the board?
