My refrigerator is making a very loud buzzing / humming noise - see video. I can hear it from another room and even from upstairs. The noise is not constant, usually it is totally silent but it will sometimes hum like this for 20+ minutes. The noise seems to be coming from the back of the fridge towards the top.

Any ideas on what is causing this?

Yes, I heard it.

Its possibly coming from one of the circuit board relay's in the back of the refrigerator.

Here's the parts diagram for your model: Parts for KitchenAid KFIV29PCMS03: Cabinet Parts
#1 is the power supply board.
#5 is the main control board.

Thanks for your input. I took this video to help too. To me, the sound seems a little louder when the door is open and seems to be coming from inside the fridge. Does this confirm your thought or any other idea?

Ok, that sounds like possibly the evaporator fan motor.
