Ok I get the DO error still after changing out the whole latch assembly and Control board all new parts, still have this DO error, I will tell you this unit had been working fine other then the bearings were bad and I changed them, reinstalled everything back and stuck with this dreaded DO error, help.

Awwite, then the most likely scenario is that one of the switches isn't wired correctly or a loose harness connector to the door latch. Use the schematic in the tech sheet to double and triple check your wiring of the door latch assembly.

No, you have to compare the wiring on the schematic with the physical location on the latch assembly. A common mistake is to switch a wire with the NO and Common terminals on a microswitch, for example. That's just an example. You need to look at every wire. There are no short cuts, no silver bullets.

I will do this again, i do agree, I can tell you though under the Diagnos. menu I can operate the door lock and door open correctly, I really dont have much left to change other then the Motor Control board, on the connections though they really only go one way, and when I do a test on the points where they connect to the board the sence and input I show my 24 vdc and open and close as the door is used, But I didnt pay attention though as too if ITS suppose to be open or closed as it should tell me in the schematic, but would the test I mention kinda tell me anyway that all is well ?

How's the door alignment? Check especially the lower corner opposite the hinge. If the door sticks out a little bit from the cabinet at that corner while closed, there's a misalignment problem that could affect the door switches in the latch assembly getting actuated.
