Laserjet M603DN tray 2 not lifting

I have a M603DN laserjet that when powered on shows tray 2 lifting continuously.
Fan 101 spins up and after a few seconds slows but never stops. No other motors turn.
Had a DC controller and power supply for another M603DN (midwest lightning) and used
them in this printer. No help. It will show if tray 2 is removed, I can access the
menus but it will not print, even from tray 1. Can't find any paper pieces anywhere
in the paper path. I've swapped the fuser from a working printer
(its gone back to the user), and I've tried to do an engine test with and without
the formatter installed. Just today I replaced the tray lift motor. The problem remains

I had a similar issue with a M602, though it's the previous generation machine they are close in design. This one kept saying tray 2 lifting but there was not a sound of the motor even trying. My first thoughts were replace the lift motor then DC controller but it was replacing the formatter that fixed it after other parts made no difference.

I was getting no response either from the machine from any tray, the engine test wouldn't work which is why I tried the DC board first & the fact the motor plugs directly into it. Depending how old yours is it might be under warranty still to cover the part.

It might be, but I should be able to do an engine test with the formatter removed. Tray 2 should lift without a formatter board installed.

Yeah it should, I don't recall if mine even worked trying that or not been too long.

Found that PS106 and PS103 are bad and can't be replaced. I now have some spare parts for next time.
