Hello, just took delivery of my first Haas today. It's been a long time coming so I'm excited.

After plugging the power in and providing air, I turned on the machine and received the message that the door is open. I cycled the doors a few times (mine has a sliding window and refrigerator-like door.) but that hasn't simmered down the Door Open or Door Hold messages. My machine is older so I figured I'd temporarily try the setting 51 trick (you'd think setting 51 would be much more interesting such as Area 51 shares the same digits). But after overriding setting 51, the controls then say Door Hold.

I haven't been able to figure out where any of the door sensors are to try to toggle the switch or troubleshoot.

Thoughts?

Thanks.
