Fridge running on AC while closed

[Sopper]

All,

I have a 2010 Trailmanor 2720 and was curious to know if the Norcold fridge would run while the camper is closed. I have heard it will run of DC or propane when closed, but am uncertain if it would do the same on shore power. I would certainly run the fridge fan...but am curious as we like to load the camper a day or two ahead of time and would like for the fridge to be cold up until we unplug at home and drive to our camp location.

Thanks in advance for any information you may be able to lend!
