Loud fan noise freezer not defrosting Clint K. • Cedarville, OH • September 09, 2014 Appliance: Model SEARS FRENCH DOOR FRIDGE. My Repair & Advice Found two very large chunks of ice on the cooling coils and the fan surrounded by ice. Once the rear shield piece was removed (without having to remove the ice-maker) the thermostat was easily found and replaced. I am hoping this was the problem. It will take time to truly tell.
