So I have a mavic air and during a flight it reported that the CPU had overheated and it needed to land so I did that landed and upon inspection I noticed that the phone for the CPU was not spinning at all I tried to move a gently with my fingers and it had no resistance so nothing was bro block blocking the propeller. So I figured it was just a faulty fan and purchased a new one and put the new one in and the same issue occurred now how would I be able to ascertain whether I need to get a new board or if there's some some simple little thing that I can do directify this. Any suggestions?
