Dometic Fridge not powering on

[Fidaddy]

My Dometic fridge isn’t turning on, I just installed new batteries and still not powering on. I checked all the fuses and all good. It’s like no power at all when I press the on button. Am I missing something? I checked the GFI also.
Thx in advance

Which model fridge do you have?

Did you check the fuses on the board in the back of the fridge?
Have you tested for voltage to the fridge, both 12 volts and 120 volts?

Thx Bama,
Only thing I need the check is the Thermal fuse, all other fuses are good.
