The main fan would be in the right side door behind the transfer/ transport section. Sometimes a small piece of paper can stop it from moving.

According to the manual the problem is the M5 cooling fan motor, there is other fan near it, the M6 cooling fan but the trouble code for it is C5353, and this is the UI cooling fan.

PWB-A is defective. Check ICP3 on it. If it's open then, IC26 on this board is shorted (MTD2003F). I had that twice 2 years ago.
