Over the last few days I've noiced a buzzing noise coming from the refrigerator. It starts buzzing and then you hear a click sound and it stops. It's getting worse. Today it's been nearly continuous. It's a kenmore elite 3 door - french doors on fridge and pull out drawer below. At first it sounded like the ice maker. I turned it off and back on by raising and lowering the lever. Just now checked to see if it's making ice but doesn't look like it BUT I just noticed the ice has liquid water inside. Feels warmer. I think the freezer has stopped working. UGH- any way to resolve this? Any idea what has happened? Do I need to call out Sears? I've paid so much money in the last few months from pipe clogs and appliance problems...broken this, broken that. Renting sure would be cheaper! Thanks in advance for your help!
