Any advise would be great.
In the freezer section, you'll find a few bolts with washers behind them. These are the heat transfer locations that allow the unit to get cold. Are they cold at all?
If your unit has auto defrost and these 'buttons' are not cold, I would suspect that your auto-defrost mechanism, usually located in your control board, is malfunctioning and causing the defrost heater to remain on. This will negate all of the cooling effects of your unit! If the coils and tubing at the rear of the unit are uniformly warm to hot, then it would re-inforce this diagnosis.
I would find a competent Factory authorized Dometic repair center and have them test your board to see if that is the problem. It may be as simple as replacing that board.
