I have an issue with my refrigerator being too warm. There is also some condensation making shelves wet, and water dripping from vents but this may be the condensation. Freezer seems to be OK. When I took the back panel of freezer off (after one hour after the defrost cycle) I noticed that only a small section of fins freezing over, not the whole grid. I don't know if it should all have frost after 1-hour? The condenser is also very hot to the touch... normal? Wondering if I have some switch or thermostat going bad. Wondering what parts I can try replacing. Any thoughts?

Thanks,

Marc
