A buzzing or humming noise just started. I checked the ice maker and don't see a problem. The noise seems to be coming from the freezer side but I hear it on the refrig side as well.

Most likely a noise from the freezer fan motor. Possibly the plastic blades are cracked or a piece broke off causing an off balance condition. They could also be rubbing some excess ice back there.

is your ice maker hooked up?if no water is going to the ice maker and the arm is down it will buzz.also check the fans one in the freezer and one in the rear for the compressor and condenser,maybe a piece of paper is hitting the fan blade when the fan starts or it could be vibration in the frame,ytou can remove the bottom kickplate and you say every half hour or so it makes the sound and listen to see if you can pinpoint the noise,when you open the freezer door the evap fan will run,you can check that fan motor like that.you have to do a little detective work to find the noise but if the ice maker isn't hooked up to the water source and the arm is down it will buzz.good luck.

Your freezer humming noise is likely coming from either the fan motor or the ice maker.

i have this problem too on my GE Profile. A youtube video seems to suggest a compressor problem. Turn off the fridge for a while and let it cool down and try again? I tried but to no avail. Would someone answer this? Please :)

need to remove rear panel inside of freezer section. check for normal operation of evap fan motor. check for ice build up on evap.

you may have a fan problem or ice maker open freezer switch on the frame freezer side press it you will know were the noise comming from

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 ice maker. If you don't have the water hooked up, and the ice sensor bar is in the down position, the ice maker assembly will attempt to make ice continuously.
Solution is easy: raise the ice sensor bar until it clicks in the up position. It will lock in this position, and the ice maker will not cycle anymore.

Sounds like the fan is hitting some ice build-up. If you can access the area of the fan motor you can try a hair dryer to defrost the ice out of it.

check your freezer for ice. do you have alot of ice in your ice maker tray? if so your water line could be frozen. try to self defrost the freezer for about 3hrs to thaw out the water line. check your water valve also. when you call for water do you hear a humming or buzzing noise? on ge fridges ive worked on if you hear a humming noise when calling for water, most likely your water valve is ok. trace the water. meaning where does the water start? at the wall then through a hose then to your valve which is behind fridge on bottom. trace the hoses and you will find the prob
