My 4 and half year old fridge freezer is giving me problems. At first there was ice in the veggie drawer which made my veggies all soft, then the internal water tank split which I changed. Recently the display is working intermittently supposed to be 5 light on each sides panel but is now show no light or one on the freezer side and none on the fridge. My fridge is not cooling. Is it the control panel. Please help
