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.

Steph,
The beeping usually means that the temp is getting to high……….
Check temp settings and that the door is fully closed and sealed.
Try unplugging the Hisense bar fridge for 5 minutes and see if that resets it.

My Hisense HR6BF157R bar fridge is making a beeping sound (almost chirping). It’s not consistent though. Some times it’s about once a minute but sometimes ten minutes or more will pass without the sound.
Nina,
Where is the buzzing sound coming from on your Whirlpool refrigerator?
It may be one of the fans. One behind the freezer and one in the bottom back of the fridge.
If the noise ONLY happens when the compressor is running, you could have a compressor that is loose and vibrating against the base. Tightening the bolts that hold the compressor to its base may solve the buzzing noise.
Let us know what you find.

My 6 month old Whirlpool model number wrx735sdbm00 is making a buzzing whining sound when the compressor kicks on and buzzes throughout it running. For the last 3 weeks. The service repair man changed a damper in the ice machine and this did not solve the problem. I have not noticed any change in temperature. What else can we look into?
I have a Samsung side by side. I purchased this in November 2009. I noticed months ago a high pitched sound, not super loud but you can hear it in the next room. Twice now I noticed the small rug in front of the refrigerator was wet (heavy duty outdoor type mat) and underneath water,. It is not coming from the freezer but from the inside of the refrigerator itself, down under the last bin for fruit. The temps are all doing good, nothing has changed, food is frozen on the freezer side and on the refrigerator side cold. Some water on the floor under the back of the refrigerator side.
Sweden,
Most likely the fan or compressor is creating the noise. The compressor may be going bad or possibly the fan is making the high pitched noise when the compressor is running. Can you not look at the back of the fridge when the high pitch noise occurs and find the part that is making the noise? If it is the compressor, replace the mini fridge. If it is the fan, replace the fan as they are cheap and easy to install.

There is a mini fridge in my office that has a high pitched whine that happens every 2 hours or so. It will build up to a louder pitch, and sometimes stop on it’s own, or else I will have to unplug and replug the fridge, which stops it. Any Ideas what it could be?
