How do you turn off the residential fridge?

Google demo or display mode for your refrigerator model number. Mine is hold the power freeze and freezer buttons down at the same time. After a few seconds it will beep. Now the lights will come on when you open the doors but the compressor will not come on. That is so appliance stores can show them without the compressor running.

For long term storage when I want to prop the doors open, I flip the breaker and make sure the invertor is off. I don't do this when I'm using my trailer regularly because it kills some of the outlets also...
