If your General Electric refrigerator started making a loud buzzing sound that emanates from the freezer, just turn up the refrigerator (not freezer) temperature setting, until the fan slows down. That will stop the buzzing.
Symptoms:
On the other hand, when ice forms on the evaporator fan, you'll soon know about it: As ice builds up on the fan blades, the blades begin to vibrate. That can build into a loud buzzing noise that's impossible to ignore. Eventually though, you will need to melt the frost stuck to the fan blades to completely remove the buzzing sound.
Here are your two options:
Speed-defrost: Unplug the fridge, and warm the (empty) freezer with a hair dryer or heat gun (on low). It just takes about 5 minutes. But you do need to be careful: Even a hair dryer can melt plastic parts! So keep it moving, and monitor the temperature with your hand.
Normal-defrost: Remove the frozen food and leave the fridge unplugged (with the freezer door open), until the entire back wall of the freezer is warm to the touch and until the ice on the fan melts. This may take several hours, but it's easy to do.
Either way, once all the frost build-up is gone, the fan will quiet down. Plus your fridge will be more efficient, allowing the compressor to run less often.
I have added more information below on normal sounds that your refrigerator makes.
Refrigerator - Sounds and Noises a Refrigerator Makes
The normal operation of your refrigerator will cause some sound. The following list contains sounds that are normal.
• A Chirping/barking/woof/howl sound can sometimes be heard as the damper door opens/closes.
• A change in fan speed as the refrigerator responds to changes in temperature due to door opening.
• A clicking/tic toc noise can be heard when the defrost timer switches on and off.
• A click can be heard when the temperature control unit turns the unit on and off.
• A boiling, gurgling, or knocking sound can be heard when the unit is running. This is caused by the circulation of refrigerant.
• Gurgling sound in the door. This sound can be heard just after the door is closed because of the water in drain tube trap area. It can last several seconds.
• A drip may be heard when defrost water is dripping into the pan beneath the refrigerator.
• The icemaker will make a loud noise when cubes are dropped into the bucket.
• A hum or click can be heard when the icemaker fills with water. This sound may be heard once or multiple times.
• A cracking or popping sound can be heard when evaporator coils on Top Mount No Frost models are cooling after defrost.
• Buzzing noises can be heard after getting water from the door dispenser. The noise should not last longer than 7 seconds.
• A snapping sound will be heard about 4 seconds after removing a glass from a dispenser. This is the sound of the dispenser chute closing.
• A clicking noise may be heard after a power shortage. This stems from the compressor trying to re-start itself. The noise could last for 3 to 5 minutes.
• A hissing, sizzling, buzzing, or arching noise may be heard on self-defrost models. This is produced when water drips on defrost heaters.
