Firstly thanks for the manual,
Secondly the error described in the manual is "locked indoor fan".
What is the reason for this error?
The fan or the circuit border?

The dc fan motor accept the 15 dc volt but it should emit a voltage~signal towardsthe circuit so ad to the latter realise that the fan is working well.Am i right?

Re: fujitsu inverter problem
If 15vdc (between black and white wire) and check 300vdc (between black and red wire) is present that motor is broken.

Re: fujitsu inverter problem
It is dc motor. Can not ping the coil because between connector and windings there is IC driver.
