Periodically throughout the day there is a loud motor noise.

Many ice maker sporadically turn to keep ice from freezing together and becoming a solid block of ice. This would occur even if the ice maker is turned off in order to keep the ice already made from freezing. It is generally short and not that loud. I'm surprised you find it disturbing.

When a start relay and the coil that opens the water for the ice maker or the water dispenser begin to weaken they some times buzz. Its possible you will need to either replace the=> 67003753 Water Inlet Valve


or the compressor=> 67005560 Relay or overload with run capacitor

it sounds like the evaporator fan blade is hitting some ice that has built up around the blades i have seen this happen a lot on g.e. SxS lately,if you can remove the ice maker and dispenser you can see the fan blade,if you dont want to do this then shut down the refrigerator and leave freezer door open and heat it carefully with a hairdrier to speed the process up to melt this ice then restart it and the noise should be gone

Two main possibilities:
1.) If the refrigerator has an ice maker but you are not making ice, the solenoid valve will open every hour or so to allow water to fill the ice maker. That valve wears out and makes more noise as it ages. There is a metal rod/bar that can be lifted up to stop the ice maker from cycling.

The compressor and the associated starter cap may be failing and it can make odd noises when it starts back up after the defrost cycle. Time for a professional to take a look.

Hi,

This noise is most likely coming from the evaporator fan motor that is located behind the panel just below the ice maker. There is an air duct that the fan blows through to cool the ice maker that is why the sound is heard in the ice maker area more.

The noise does not hurt anything but the motor can be replaced if it gets too annoying, it is a fairly common complaint. The part number for the motor is WR60X10185 and runs about $60.00. It is a bit challenging to get to but can be done with a bit of patience by removing everything in the freezer and taking the back panel off the inside of the freezer.

Dripping sound.
During the defrost, water draining from the freezer section will drip into the pan by your compressor in the back and bottom of your refrigerator.
* Air rushing or blowing.
There is a fan in the freezer section and in some models in the back and bottom of your refrigerator to circulate air. This is a normal sound.
* Louder when starting or coming on.
Compressor operates at a higher pressure when first starting and noise should disappear as refrigerator continues to run and balance pressures.
* Popping, crackling, or sizzling about once a day.
If your model is self-defrosting, the defrost system utilizes a heater to remove the ice and frost from the freezer coil. During this period you will hear some expansion noises as heat is applied to the coil and you may experience some sizzling sounds as the melting water drips on the heater.
* Running water.
If you have an ice maker equipped model, the ice maker will call for water as the old batch of cubes is ejected and the ice maker starts to make more cubes. This will last for about 10 seconds and is normal.
* Vibrating or rattling noises

fan motor probably rubbing in something

I have the GE profile Refrigerator with ice maker in the refrigerator compartment. Mine was knocking loudly for long periods of time, so I finally removed the icemaker by removing the side panel in the icemaker compartment held with 1 phillips head screw, disconnecting the electrical plug (unclip), pulling the tab of the icemaker down (on top) and sliding it toward the door, thus removing it. There was ice frozen in the motor compartment that was the problem. I let it thaw out and re-installed. All was OK after that..

Sounds like the freezer fan blade is hitting on a build up of ice or frost. You may have a defrost issue, or it may be a one time thing, like the door was open for a long time (object holding door partially open) or also check the ice dispenser duct door to make sure it is closing. Sometimes a chunk of ice hangs up in the ice shoot, allowing moist air to enter freezer, resulting in the extra frost / ice near the freezer fan. You might also check the door gaskets, especially the bottom side where sugary liquid spills might cause a gasket to tear. #2: Long run times: If cooling is good, don't worry. Older refrig's often ran less time, but used much more electricity than the newer refrig's, even though new one run longer. (Like having a 40 watt light bulb on for 20 hours a day uses less electricity than having a 100 watt bulb on for 10 hours a day)

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.
