Dometic RM 1350 Fridge cooling question

The fridge seems to work correctly on both gas or electric. Here's my question, the temp on the eyebrow says the fridge is at 33 deg. but the thermometers in the fridge read 40 and freezer reads 3 deg. So what's the problem the thermistor, eyebrow board or where is the temp sensor because I think the temp should be a bit colder. accepting all suggestions and ideas.
