Hi Freddy.
just to confirm what you already state. when i check against the alarm codes i have for a different model to yours listed. It say's Motor of compressor (1,2,3 or 4) overheated or any fault.
Some diagnostic checks on your system are needed.
Just humour me, try disconnecting the suspect fan electrically ( pulling fuses is usually the favorite!) and run the system. Because as Frank rightly says on a multi fan system. it is quite common to see adjacent fans spinning in the opposite direction albeit slower! Provided you have a wiring system, it should be relatively easy to identify where the fault is.
Good luck grizzly
