My Samsung refrigerator occasionally makes a buzzing sound.

I have encountered numerous issues like this one. Normally, when you unplug a refrigerator, all mechanical noises should cease operating. A buzzing sound may be emanating from some other appliance, clock, or other product in close proximity, transmitting a frequency toward your unit. Basically if there is no power supplied to the unit, it virtually can make no noise.

Fridge keeps beeping or buzzing: The following is for Frigidaire models but others can be addressed similarly.

Several Frigidaire refrigerator models have an electronic control panel on the freezer door the owner can use to adjust the internal temperature, dispense ice and water and receive notification about issues such as the need to replace a water filter. The refrigerators also emit a beep for various actions and as an occasional alarm. Determining what causes the beeps necessitates some troubleshooting.
Temperature Controls ·A Frigidaire refrigerator's display panel blinks when the control panel is touched to set temperature controls. After pressing "Freezer Temp" or "Refrigerator Temp" on the keypad, press the arrow buttons within five seconds to increase or decrease the desired temperature. If you do not press the arrow buttons within five seconds after pressing "Freezer Temp" or "Refrigerator Temp" on the keypad, the refrigerator beeps to indicate the current setting will stay in place.

Door Open ·When you leave the refrigerator or freezer door open, the refrigerator beeps. Also, the "Door Ajar" indicator illuminates on the appliance's display panel. Shutting the door and pressing "Alarm Reset" stops the beeping and turns off the "Door Ajar" indicator light.
·The Frigidaire refrigerator has a control lock feature that prevents use of its control panel or dispensers when the unit is locked. When the control lock is active, a beep sounds when a keypad or dispenser is pressed. Release the control lock by pressing the "Control Lock" icon for three seconds. A beep will sound, and the icon's light will go out.
Power Reset ·A power reset is occasionally necessary if the Frigidaire refrigerator's control panel does not work normally or a reset function on the keypad does not work. A power reset involves disconnecting power to the refrigerator by unplugging its power cord from the electrical outlet, waiting 30 seconds and plugging the power cord back into the electrical outlet. When the control panel resets, a beep sounds. If the refrigerator beeps even after a power reset and the beeps' source is not known, contact Frigidaire.

Your refrigerator has at least three motors with fans in addition to the compressor motor. The one most suspect is the one that passes air from the freezer to the refrigerator.

On some models of refrigerators, the evaporator fan (behind an access panel at the top of the freezer) shuts off when the door is opened. This fan may be making the buzzing sound.

You should be able to check by pushing in the door switch while holding the door open. The fan should come on; and, if the buzzing resumes, you know what is making the noise. The fan may be developing a problem. If it stops running, the cold air will not be distributed properly between the freezer and refrigerator.

Sounds to me the dual water control valve is becoming defective. Thats the sound when it sends a signal from the ice maker and the valve coil is just too weak to open the valve. Hope That answers your question, Thanks, Sea Breeze

Are you sure this noise is not just the ice maker trying to cycle without water? If it is not turned off it will dry cycle every 15 min or so.
