MAXXFAN - auto opening - keeps cycling

Hi have a MAXXFAN fan with the rain sensor, temp sensor and electric opening. From a 2014 Kodiak TT. I would love to give you the model number, but cant find it anywhere and there is no manual.

Anyways, when the electric vent opens, at the top of the opening, it clunks about 5-10 times before it stays open. I have no idea if this is normal or it may be damaging the mechanism.

Here is a youtube video: https://youtu.be/nuhkon9Sr9Y

Any ideas or suggestions?
