Hi Bob, sorry to hear about your freezer door issue. I did a quick Google search and found the
Dometic Repair Manual .
That's the page for removing the door but there's no mention of how to disassemble the freezer door itself to get to the button assembly. It sound like something in the mechanism is jammed or not connected.
You might be getting a new fridge from Airstream!
*The bedroom TV in our unit developed two horizontal lines across the screen. I emailed the dealer a photo of the screen and they opened a warranty claim with Airstream. They approved it so we're just waiting for it to arrive.
Good luck!
Jeff
