Re: Fan is making a buzzing sound

Its becoz your drawer back side is touching the fan support! You should get it repaired! it might cause fan blade to be broken!

It sounds like your evaporator fan motor, they last about 4-5 years. Try to see if the buzzing noise comes from the motor, usually in the freezer compartment behind a vented cover plate

The freezer is usually cooled by the compressor, the fridge is then cooled by an evaporator fan motor ($30). If this fan seizes or slows down then the fridge warms up (it sometimes starts squealing before this happens). It could be that your drain hose is clogged or frozen. Maybe the temperature adjuster go bumped.

If you think it is the evaporator fan motor:
Check to be sure you can get a replacement fan first, they last about 4 - 5 years. Can get from a parts supplier or electric motor company.
UNPLUG fridge. Located usually in top of freezer behind a vented cover plate. Remove cover, remove screws holding fan in, may have to cut wires. Replace with new motor, make sure the fan pushes air into the freezer area and doesn't spin backward drawing air from the freezer area.

It is making a buzzing noise on freezer side that stops when u open the door but starts again when u close it

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.

Kenmore Coldspot freezer is buzzing loudly

See if pressing on the back panal makes a difference and see if anything is putting pressure on the panel. If its vibration it is trial and error to get it positioned to quiet it down. If it is the bearing replacement is the cure.

GE Top Freezer Fridge - Freezer Buzzing

If you remove the half moon cap, and two 1/4" screws you can remove the cover and get to the fan. The fan motor shaft is mostly wobbling around making the buzzing sound.

Freezer and fridge not cold

Sounds like you have a stuck compressor. The buzz is the compressor trying to run but cannot.
A refrigeration mechanic with an hermetic compressor tester can reverse operate the compressor to get it unstuck

Freezer and refrigerator not cooling. Makes a buzzing noise

hello sbarrry2 it sound like the motor that is running continously is the condenseer fan and the buzzing and then the click would be the compressor trying to start up and going off on overlaod. shut the unit off at the swiutch, let it cool down (3) hours possibly and then try to turn it back on. this should work.

Frigidaire side-by-side model # FRS26H5ASB4 making humming or buzzing noise

I had the same problem. I found the buzzing noise was caused by ice build up around the fan motor inside the freezer. I believe water must have leaked down around the fan during a defrost cycle. I removed the ice maker, the ice cube bin and ice dispenser auger motor. It sounds complicated, but it isn't too bad. The ice maker and auger are connected with quick connect plugs. So just unplug, remove the screws and remove them from the freezer. You will need to remove several other screws as well, I believe 11 in total as well as the top freezer rack. This will give you access to the white aluminum panel that runs from the top of the freezer to about halfway down the back of the freezer. After you remove the aluminum panel you will see the fan about half way down the freezer. I found a lot of ice around my fan. The fan blades were hitting the ice causing the buzz. Remove the ice and the buzzing is gone. It took me an hour to complete this repair. I hope this helps.
