Freezer side is making an extremely loud humming sound. Ice maker is working fine. No ice buildup anywhere in the freezer that we can see. Loud humming goes on for a few minutes each hour.

The defrost system is not doing it's job. I bet if you took the panel off below the fan you will see more ice on the cooling coils. There should be a light coat of frost on the coils but not a heavy ice build up. There is a heating element at the bottom area of these coils which should be defrosting all this ice.

1. A defrost timer turns this heating element on.

2. The heating element melts the ice.

3. A thermo disc attached to the coils will turn the heater off.

One or more of these are not doing it's job.

I had the same problem. I found the buzzing noise was caused by ice build up around the fan motor inside the freezer. I believe water must have leaked down around the fan during a defrost cycle. I removed the ice maker, the ice cube bin and ice dispenser auger motor. It sounds complicated, but it isn't too bad. The ice maker and auger are connected with quick connect plugs. So just unplug, remove the screws and remove them from the freezer. You will need to remove several other screws as well, I believe 11 in total as well as the top freezer rack. This will give you access to the white aluminum panel that runs from the top of the freezer to about halfway down the back of the freezer. After you remove the aluminum panel you will see the fan about half way down the freezer. I found a lot of ice around my fan. The fan blades were hitting the ice causing the buzz. Remove the ice and the buzzing is gone. It took me an hour to complete this repair. I hope this helps.

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 had the exact same issue last night. I would press on the back panel long enough and the noise would go away only to return this morning at 4am. I finally got up took all of the bins and shelves out and found an very large accummulation of ice at the bottom (floor) and walls of the freezer. The ice accummulation was causing the rattling of the tubes in the wall of the freezer (I don't know what you call them), but they were frozen over on one side. I found this out once I took the back wall panel off of the inside of the freezer. I also found the drain hole back there and it was frozen over solid, as well as my ice dispensing unit at the top of the freezer. This whole problem began when I turned on the ice maker 3 days ago. I used my hair dryer and hot water to clear all of the ice from both areas and now it is nice and quiet. Don't know if the acccummulation is due to some defrost switch gone haywire, but at least the rattling is gone and my freezer is back to square 1 for the time being and I saved myself a visit from the appliance guy in the meantime. Took me a total of 1 1/2 hours to do it all.
