The light inside the fridge is 12v. Do you know what your voltage is?
My fridge lights blink when the propane side is not working (out of propane, air in the propane supply) etc. I've never seen that when connected to electric.
Are all the other electric outlets etc. working? Is your converter breaker switch off?
