Leave the door closed all night and check it in the morning.
You said you defrosted it because it was having trouble cooling. So while you didn't kill it by poking the hole, it might have already been dying from other causes.
If you flip it to propane and go stand outside by the refrigerator panel you should hear the flame making a dull roar. If no noise or just clicking you propane is not lighting. I would check to see if there is a fuse on the board in the back of the refrigerator. Again you're looking at the back of the refrigerator by opening the cover outside the RV.
Do you have a small desk fan or light or radio or something that you can plug into the outlet for the refrigerator and make sure it has 120 volts? Maybe the fuse in your power center is blown.
