Yes actually just ran the quick one returned "4MOT/4/40000002: Left side - 7101"
Running the extended one as we speak.
Looked this code up and could not find any info on the exact code.
I did find a "4MOT/4/40000002: Left side - 0" post that suggests that the fan motor is failing, but as stated above i have already replaced the fan with the same problem occurring. In fact I even put the old fan in another MD318 and it is working just fine.
The fan is currently over-revving and i have read that if the fan is running past 10% of its designed rpm it will return this kind of error.
I believe this is the case.
Problem is that even with a 3rd application i cant get a signal to the fan to turn down the rpm.
All of this makes me think there circuit failure on the logic board.
However, could it still read the RPM of the fan if this is the case?
EDIT
Just finished the extended hardware test returned same error
Shocking I know..
