Fridge Seems to be running odd - Says AC but running on gas

ok Totally Bizarre. My fridge indicates it is running on AC but is really running on gas and vice versa. I was able to determine this by checking the electrical connections. The fridge panel reads AC when the GFI is tripped - no outlets in the RV work, no power to the actual outlet the fridge is plugged into. This test was done using an outlet tester. When it reads AC, the gas has ignited and the blue flame is blowing. When I reset the GFI - all of the outlets come back including the one for the fridge. I plug the fridge back into the outlet, the flame from the gas cuts out but the light in the fridge panel reads LP. Seems to be cooling like it is running on AC.
The fridge seems to be working but the lights are backwards and it is irritating. I am afraid this is indicative of something else that could be hazardous. Anyone have any ideas? Thanks in advance
