Refrigerators can be noisy (clicking, buzzing, humming, high pitched squeaks) and some sounds are just a normal process of refrigeration. Sometimes a refrigerator will develop a problem and a high pitched noise can be heard. To fix this issue you must determine the source of the sound. By doing so you can locate the problem and hopefully avoid calling an appliance repair company.
TO FIX THE NOISE COMING FROM YOUR REFRIGERATOR:
You first have to do a little easy investigating. What type of noise it is that makes the refrigerator sound as if something is wrong? Is it a squeaking noise, a clicking noise, a buzzing noise, a humming noise, a loud high pitch vibration noise, or an occasional rattling noise? How loud is it and how long does the sound happen? If it is not a continuous sound, how often does it occur? Is this affecting the proper operation of your refrigerator or is it just an occasional annoyance? These factors can help you identify the source of the problem to help you to determine what you need to do to fix it.
Open the fridge freezer and determine if the noise is coming from one or the other. If the noise is inside the refrigerator… it is the circulating fan. This fan’s purpose is to move the cool air from the freezer to your refrigerator. This fan can start to make different types of noises over time. Usually the circulating fan will need to be replaced. In some situations you can take the fan out clean it off and bend or straighten the blades to make the noise stop. Usually the noise is from the motor of the fan which is not fixable. Order a new circulating fan online will be inexpensive for you to repair the problem with your fridge.
If the noise is coming from the rear or back of the refrigerator, 2 things can cause the noise:
1. Compressor (see below for troubleshooting)
2. Condenser fan (see below for troubleshooting)
Common Fridge Compressor
Common Refrigerator Condenser Fan And Motor
Compressor: The compressor contains a motor that sits in a sealed case. If it becomes faulty it can make high pitch noises. If your compressor is causing the noise, the compressor needs to be replaced and this can be expensive. It may make more sense to just buy a new refrigerator if your compressor is shot.
Condenser Fan: If you find that the condenser fan is making the noise you can clean it off from dirt and lint. A dirty condenser fan can cause the noise you are constantly hearing. It is located near the compressor and can’t be missed if you are behind your refrigerator looking for it. You can also give the fan a few drops of oil as it may just need oil to lubricate it to stop the noise.
Another area that could be making a noise on your fridge is the very bottom. A drain pan is the only thing underneath the fridge but it may need to be repositioned as it could be vibrating and causing a noise.

Lori,
There is a fan in the back portion of the freezer.
When it is spinning, it is most likely hitting the housing and making the sound.
You will have to unplug the refrigerator, take the panel off inside the freezer and check the fan.
You can possibly bend the blades so it stops hitting, or it may need to be readjusted or replaced.

My Kenmore 26 model refrigerator has a very loud, annoying humming screeching noise. Constant comes from freezer area.
We have a Maytag side by side Dual Cool refrigerator, and it was not keeping the freezer items frozen so when I read online it said the main culprit may have been the dust or pet for build up on the coils. There was some frost on the back of the freezer halfway up also. I removed the frost and I cleaned all the coils, front and back- I plugged it in and it still was not working. Now it is making a high-pitched humming sound. It is still making ice with no Icy build up on any lines. However there is some ice forming on the back of the freezer about halfway up again.
High pitched continuous tone coming from Siemens Fridge Freezer. It gets louder when door is opened.
Weird thing is it doesn’t stop even if you remove the power from it. I have now left the power off for 15 minutes and it is still very loud with the door open. It is coming from the fridge not the freezer. Normal fridge and freezer operations still seem to be working though.
Monique,
The buzzing noise you are hearing is most likely a noisy capacitor, relay, compressor, or something may simply be loose.
Unplug the machine and check to be sure all parts are secure.
If a part becomes loose it may buzz.
Usually a buzzing noise on any type of refrigeration is a cap or relay.
If it is a cap or relay, you can buy replacements very cheap online.
Let us know what you find. Give us the model number of your water cooler also.

I have a Vittapur countertop water cooler that has suddenly started making very loud noises like a buzz. How do I fix it? It sounds like it is cycling and comes from the back of the unit.
Make absolutely positive, that the appliance is level, both front-back, also side-to-side. Some makes are extremely sensitive to being level.
