Frigidaire side by side freezer - LOUD noise...

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...

Good Morning Denise, thank you for your inquiry!
From the information you have provided your Frigidaire freezer is making a buzzing noise and it will not stop. You may need to perform a reset on your freezer and you can do that by disconnecting the power cord for at least ten minutes. If the buzzing continues I would be happy to research your freezer further, in order to do so I would need your model number. You can locate the serial tag (which lists your model number) on the inside wall. Once I have that information I would be happy to help you further. -Matt

Hard to say when you don't say what kind of noise it was? Cracking, thud, hissing or what?

evaporator is probably frozen up

From what you're describing it sounds like the freezer fan motor is causing the noise you hear. The freezer fan is the only moving part in the freezer section. I recommend replacing the freezer fan motor & fan blade together. If there is ice buildup on the back wall of the freezer then the sound is likely from the fan blade hitting the ice and you will need to defrost the unit.

the loud buzzing is the freezer high temp alarm. dont know why its warm though.
make sure you don't store anything on top of or on the sides of the unit as the condenser of most freezers are buried in the walls of the unit and it will over heat the compressor. if unit is in a hot garage this will compound the problem.

fan motor probably rubbing in something

it sounds like the compressor, or something near it. it is generally the only moving part in a refrigerator other than the door, so would be my first guess. If it is constantly running, but staying cool in the freezer there may be a small leak somewhere or the compressor is losing power, and pumping slower.

If it is the compressor making that sound,The compressor is bad.
A fan motor can as make this type of noise as well when going bad.
If it is the fan motor stopping,this will also shut the compressor down,due to the thermal overload protection.



Please rate this a fixya.

at 6 years old it certainly aint new!
from what you describe, sounds like a compressor fault
