Before replacing the engine PWB, try upgrading the firmware. Also, did you run U037 to see if the fan motor comes on? If not, replace the fan motor and make sure you check the wiring.

Before you do that, put your meter on the fan leads, then test FURFM in U037 > Fuser Cooling. You should get 24vdc across the leads with the fan turned ON. If there is no voltage at the fan, track that signal back to Engine PWB: YC26 A8 to A9. Also check the Alarm signal Engine PWB: YC26 A7 to frame ground, changes 0 to 3.3vdc. Meter out the harness.

That should keep you busy for a while. =^..^=

have you done a fuser reset? u163

BillyCarpenter:
U037 - Fuser Cooling Fuser rear fan motor (FURFM) is turned on - NOTHING TURNED ON
I tried changing 2 pieces of fans - nothing happened (still C6930)

I tried to upgrade firmware and check the wires - thank you

blackcat 4866:
yes this checking of the voltage will keep me busy for a while Thank you.

Luther:
I do not try U163 - very good idea - I will try it. Thank you.

Thank you all!

Please BlackCat I am crazy of this fan location.
Where is the correct fan location in picture attached?
The service manual says:"Fuser edge fan motor 2" and in which side must I go to disasembly (from the rear, front or side way)?

You can see in the diagram that Item 37 (fan) is connected to a cooling duct that comes out on the upper rear of the machine. You can't miss it. Trace the air duct back to the fan.
