GE Artctica makes "knocking" sound every 3 to 5 minutes. How do you get the "roof" housing, under the light on the refrierator side, off? My husband thinks he can locate the problem but doesn't want to break the plastic trying to get if off.
Remove the light shield and there should be screws under it. Remove the air tower in the back, it snaps in and there is 2 screws behind that as well to remove the damper housing that sits behind the light. Also not sure what your model is but some models have 2 air ducts that run up each side, they come out after the light shield is removed by sliding foward and then pulling down. After the screws are removed in the upper plate the light assy will snap out and there is 2 quick disconnects on the wires.
Kitcheaid side-by=side started making knocking noise. I discovered it to be the water line to fridge (for ice & water dispenser). It was actually shaking and hitting fridge and wall. It would do this even after unplugging the fridge. After some sleuthing, I discovered it was a leaking toilet in master bedroom. Once that was fixed, the knocking stopped. Now whenever water is turned on and off anywhere in the house, I can hear the water line hit the back of the fridge. Now I just need to tape it down better.

Pull the fridge away from the wall and inspect the compressor. Your description sounds like the compressor is hitting something. It is rubber mounted and usually can be pushed away from whatever it is hitting.You do not want to jamb something to stop the noise, as the compressor needs to move freely. Many compressors shake during start up and shutdown, and this is considered normal. Abnormal if the compressor hits something during this movement.
Problems not related. The first is most likely the fan, or possibly water dripping on to the fan and freezing, but usually the noise comes from the fan struggling to run. The cube problem could be as simple as the ice dispenser being put back in wrong. There is a metal lever under the ice tray that switches between crushed and cubed. Make sure it is seated properly.
Unplug and closely examine the area for a loose fan blade or anything that may be causing the noise. Better now than to get damage that could be prevented. Let me know what you find, Thanks, Sea Breeze
Check the compressor mounts. They are usually springs mounted with rubber. If they are two loose the compessor wil hit some other metal part when starting up. Shakle it and see what it is hitting. Ajust accordingly.
I also have a new Whirlpool Gold fridge (bottom freezer with French doors) and it was making a knocking sound. The knocking sound would start when the fridge kicks in and starts running to cool, and would last for about a minute or less and be a slow knock.
I called Whirpool customer service since it is new and on warranty. They sent out a technician and he said the knocking is from gas/air built up in the copper tubing for the freezer because the copper tubing is too cold, and when the fridge first turns on it forces the air through, making the knocking sound.
His "fix" was to adjust the copper tubing so that it is closer to the heat of the motor/compressor and heat of another copper line so that the cooler line stays warm so the air/gas doesn't build up. His fix worked slightly, but the fridge is still knocking, just not as bad and not as long - it knocks fast for about 5 to 10 seconds instead of a minute.
Going to call customer service again soon and see where to go from here.
If you have it, the owners manual will describe what strange sounds it makes. It sort of sounds like normal popping that the system makes when the refrigerant flashes to a gas in the evaporator section. This sometimes happens with age and is fairly normal. If that's what it is there's no cause for alarm. I can't think of anything else that would make the noise you describe.
