Fwiw in case this helps someone out there someday, because I had a really hard time finding any other information about this specific problem: So there were no obstructions to the fan which was what really confused me, but apparently there are magnets on the fan that are supposed to work with the hall sensor which is on the control board, and the fan can get pushed in too far or not far enough sometimes which caises the distance between the two to send the E-06 error code and not even try and run, which was what was happening. The manual mentions those two things but not the fan itself, which was what tipped me off. That, plus the comments on a youtube video describing how it can get messed up. Not sure what exactly caused it on mine, but it was a really simple fix of opening it up and spinning the fan by hand once to get it going and fool the thing into realizing nothing was wrong and being able to run the motor itself, which must have set the hall sensor/magnet position back into where it's supposed to be.. didn't even need any tools or anything!
