The lack of anything on the display lists 4 things to check.
Have you verified that there is 12V-dc power at the terminal block in the rear of the refrigerator? You should find that terminal block on the floor of the space inside of the rear access panel and usually, it is to the left side, near the 120V power outlet. If you do not have power there, you must find what the course is. In most cases, there is a fuse on the RV's 12V distribution panel that supplies it. There is also a 3A fuse on the main circuit board for the 12V supply. Either of those will give the symptom that you have.
My refrigerator was having the same issues as everyone else, no power. After checking all fuses and replacing the circuit board with still no power, I found out that there is a “Snap” fuse located on the propane gas vent that went bad. This is a fuse that will cut the 12volt power off to the fridge if the stack over heats reducing risk of fire. It also cuts power to the gas valve as well. After replacing this “snap” fuse, power was restored to the circuit board and everything is working as it should. Wish I had known about it before replacing the circuit board. $30 snap fuse, while circuit board cost me $120. Still better than replacing entire refrigerator.
Good luck and I hope this information helps someone else.
