Norcold not switching to propane in auto mode

I guess I was a bit vague, which comes with being chronologically challenged. I just opened the door a minute ago after I got up. It worked fine all night. When I opened the door the interior light went out instantly and the door open beeper started singing. I turned it off and then back on and it's working fine. Still will not switch to propane.

Sitting here scratching my head????? I just hope it keeps working like it is now until we get home in two weeks.
