Ventless dryer help!!

[Kanda.Cane]

I have a ventless dryer, model #417.81912510.

 the timed dry doesn't work it says "not possible" and it doesn't get hot, it stops before the run time is done, heating element is good I checked the main control board and it's good.

I ran it 3x and it stopped within 10 mins, then I relied it the 4th time and within 5 mins it stops but then it tumbles the opposite direction for a couple of mins the goes the other direction and it's tumbling faster and the blower wheel sounds like it's blowing harder.

any ideas?
