Samsung RS261 humming noise from the freezer

SOURCE: Frigidaire Frig side by side making a loud buzzing noise

it sounds like the compressor, or something near it. it is generally the only moving part in a refrigerator other than the door, so would be my first guess. If it is constantly running, but staying cool in the freezer there may be a small leak somewhere or the compressor is losing power, and pumping slower.

I just worked on a FF801W which is supposed to be very similar. The defrost heater in mine was of the glass tube type and located under the evaporator. There was a bimetal thermostat clipped to the top of the evaporator and a thermal fuse (sealed in a clear plastic tube) nearby. The connections were behind a little plastic cover (2 screws) in the back wall just above the evaporator.

Mine was iced up like yours and I had to defrost it with a hair dryer. All the defrosting parts in the freezer compartment turned out to work so I now suspect the defrost timer (down by the compressor). I've marked it and I'm waiting to see if it's turning.

I think the Adaptive Defrost Control may be your problem part number 12566102 You may find it inside the fresh food compartment and behind the controls where you adjust the tempertaures. I will return with photos and links, Sea Breeze

I believe what is happening, is your Evap fan has some build-up of ice on it. The reason it stops when you open the door, is the Evap fan cuts off. The Evap fan starts back up when the door is closed. What you'll need to do, is open the freezer door, and remove the back panel of the freezer. This takes some 1/4 inch screws and a couple Phillips I believe. Once you get the panel off you'll be able to see if there is any ice build-up on the Evap fan. If need, be take a hair-dryer on medium or low, and melt the ice off of it. This should solve your problem.
