The gimbal motor is a stepper motor.The driver circuit takes input from a 3 way axis sensor to keep the camera pointed in a fixed direction regardless of the aircraft orientation. If it is buzzing, the driver circuit is likely trying to get it in position, but it keeps dropping back. Since you replaced the motor, it might be that a wire is not connected so the stepper motor can't hold its position.

I have replaced a gimble assy, on a Mavic 2 Zoom and a camera/gimble wire on a Mavic Pro. Both gimbals work, but the Mavic Pro camera does not. I can't figure out how to test whether it is the camera or the circuit board. The Mavic Pro wires were ripped out when it fell thru a tree.
