Kenmore side byside refrigerator

Question edited for clarity.

It sounds like the compressor is struggling / overheating / failing. When was the last time your stripped the back out and removed all the fluff and debris? It overworks the compressor and gets red hot when the condenser coils get blocked. The struggling compressor causes the humming. Turn it off, keep the doors closed and vacuum it all out. Clean underneath and you might as well clean the floor and walls around it as the plan is to leave it disconnected for 1 to 2 hours to cool down and settle the refrigerant gas/liquid. Some other ideas below.

The evaporator fan motor circulates air over the coils to help keep things cool inside your fridge. If this motor starts to go bad, it will make a buzzing sound as it struggles to circulate air. You'll need to replace the evaporator fan motor to fix this problem.

Frigidaire Refrigerator Runs Loud? This May Be Why...

Happens when the bearings in the fan or compressor motor are getting worn out. make sure there isn't a piece of cardboard cowling or debris hitting the fan.

Hi,

Here is a tip that I wrote about refrigerators and the fan noisethat they develop sometimes...

RefrigeratorFan Noise

It sounds like the evaporator fan is hitting ice that is built up on the evaporator coil. When it's making the noise, open the freezer door and see if it stops.
(Most models are wired so that the evaporator fan cuts off when the freezer door is open.)
Check the inside back, lower panel of the freezer for ice built up or frost on it. If there is, you have a defrost problem that is most likley a bad heater. It's located around the coil inside the freezer behind the panel you will be looking at. The defrost problem would explain the freezer not freezing ice cream.

fan motor probably rubbing in something

Has anything changed in the cooling? Can you locate the model number on your refrigerator.The noise is coming from under or inside the refrigerator or freezer? Let me know those few things and we will find out whats going on, Thank, Sea Breeze

That sound is usually your icemaker calling for water. you can turn off your icemaker by lifting the little arm on the icemaker. As the icemaker calls for water the valve will be activated and will hum. This sound is usually not very loud. If your valve is making that much noise you may consider replacing the valve. The part number for you water inlet valve is #2315533 The retail price is $60.18 . I do have these on hand and available to ship out today if you need one. Please just let me know. You may also consider replacing your filter if your refrigerator has one. Thanks and I hope this will fixYa
