DC5000 tray 2 failure

[davidj7]

Hi
It all started with a broken interlock switch 110E12610 after replacing the switch. I am getting Tray 2 failure.

Tried to run the tray lift motor from component control .It wont budge.Inter changed the motor in tray 1. The motor works fine in tray 1.All the tray size sensors are working

I checked the fuses F1 to F7 all of em checked out. Before i touched the PWB(since tray1 is working) is there anything else I am missing or should i check before i touch the PWB .

Thanks
David

update: I interchanged the tray switches from a working machine .No change
Interchanged the FFM PWB with that of the working machine . No change .

I dont think its an IOT issue . Cause everything else is working fine.What am I missing .Any suggestions welcome
