T200 Thruster making jerking motion

Using T200 with Pixhawk and ardusub. This particular thruster is not rotating making a jerking motion and stops after a few seconds and only the licking noise comes. Please Help.
Video link is attached:

They usually do this when one of the phases is not connected.

Hi,
Thank you for the responce. Then what should I do next? It is a new one never used.

Hi @avilash,

It looks like you are using an old thruster with the integrated Blue ESC, these have not been manufactured or sold since April 2016. Please contact support@bluerobobotics.com with your order number.
