hi there, we have an RM2262 model fridge and i may appear stupid but was looking at older posts and came across one saying that the freezer section keeps the fridge cool. is this right? our freezer section does seem to be working except on very hot days when it defrosts itself, but the large fridge element does nothing at all and so i take off the freezer door to keep the rest of the fridge cool. am i doing wrong? should the fridge element get cold too? user manual not too helpfull really. we are about to use the van again next week and so would like to find answers to these questions before we go really, any help appreciated. thanks, teen
