Hi,
I tried turning on my ST-862D station tonight and I got an E11 (broken fan) error. I think it might be the 6th time I use it and it was working perfectly before. I looked at the fan and it does at least turn freely. Also I looked at the transformer and the 24 V output looks ok. It does not seem to be a very common error based on googling it. Do you think it is likely to be a defective fan motor? Has the fan some kind of 24V 4-wire PWM pin out?
Thanks!
