Fujitsu split fan motor

Howdy - looking at a condenser - mod:AOT30LMADL.
Condenser fan not working - no power to the motor, do i just order up the circuit board or is there a common sensor fault not bringing it in like with some other models?
Pls let me know your ideas??
Thanx..

Probably the relay on the PCB. There are a couple of relays to control the fan. One to provide the power (K13) and another to switch between the speeds (K11). You can try giving the power supply relay K13 a little whack, might prove a point. Chances are the relay contacts have gone a bit pear shaped.
On the motor plug white is neutral, black is start winding which goes back into PCB to capacitor then to neutral, red and blue are the 2 speeds, guess you might have already figured that out though.

Thermistors shouldn't hold fan out, especially if you test in both modes. Always worth checking them though, got a sheet attached.

Cheers!
