KR-V7070 problem with fan control circuit

[Lino]

I'm chasing schematics for Kenwood receiver to troubleshoot a fault with the
fan control circuit...fan goes on for about half a second then shuts
down...the receiver shuts down after warming up I presume because of the fan
not coming on...any ideas
cheers

Fan itself is faulty?
If you can easily stop it manaully and it has troubles rstarting, motor is
probably bad.
