Refrigerator problem help

I have a dometic freedom fridge and my 120v power will not work but it will work on dc power. I am getting 120v to the board but it just won't light up the control panel or turn on

Welcome to iRV2.
The control panel on my Dometic fridge is 12v powered , and uses relays, and a circuit board, to turn on the 120v heater and 12v solenoids to control the propane.
Am I understanding your post correctly.
When you plug in to shore power the fridge won't operate because the control board won't light up ?

Have you checked the operation of your converter/charger?
What year is the fridge and RV?

Yes I have checked my converter the only thing I came up with was that the hot and neutral are reversed in all my 120 outlets. Could this give me irregular voltage?

The 120 VAC is at the control board because the board switches it on and off to control the AC element. There should also be 12 VDC and ground on the board to run it. There will also be a switched 12 V line to run the gas solenoid valve. Not sure whether it switches hot or ground.

Reversed AC should not matter.
