C450 code C2352

[morgan]

Have a C2352 code on C450( toner suction fan motor failure to turn). I have replaced motor m20 and checked connectors for all 4 fans. all 4 fans are turning on boot up, m20 is turning. i have tested the pwb-m board on another c450- no error. have loaded ltest roms and firmware. unit on its way back to workshop, any ideas please

Only solution I could find from Minolta was: C2351 or C2352 shortly after power up was either bad fan, loose connection, or connectors to PWB-MC cooling fans (M24) or M are switched.

That was M24 and M25. Sorry, left that out.
