Hello, my name is XXXXX XXXXX iam happy to help you with your question today..if you flick the lite switch multiple times does it stay on sometimes? or react erratically?
If it is a intermittant switch and leaves the lite bulb on constantly that will definately generate heat in the fridge section , ive had those switch stick , if you slowly close the fridge door can you see the lite go off inside?it should go off with about 1/2" left before the door closes..if the switch is intermittant ,I would agree with you that is the issue with the cooling , and changing the switch would be reqd
maybe take the bulbs out for a day or so ,and see if any problems return , seems a bit strange that the heat is so high , freezer blows cold air into the fridge section , if the bulb was on 24/7 it would cause excessive heat ,if all ok after a few days i would change the lite switches ,just to be safe
yes , you can do that as well , the fridge is just a cabinet ,that receives cool air from the freezer , the only thing in the fridge section that could possibly cause any heat are the lite bulbs , it can only be from the bulbs
ok ,good luck , have a great weekend
