Ice/cold room chiller fan noise

Question edited for clarity, MAKER.
Question moved to Model Category.

Your fridge freezer has three fans.

The compressor evaporator fan cuts in and out as required to maintain temperature.

The fridge evaporator circulation fan runs to maintain an even temperature. It stops when to open the door and resumes when you close it and stops when the set temperature is reached as long as the compressor isn't running. If the compressor is running, the fan normally runs to prevent icing which happens slowly.

The freezer also has a fan, and that runs pretty much all the time unless target temperature is met and the compressor is not running. This fan runs when you open the door to stop the moist air from the room freezing on contact to the 0'F, -18'C evaporator fins. The fan keeps the air moving to deposit less frost.

It sounds like your is running normally except for the noise. Trace the noise and find it. The compressor fan has a Shark Paper fibre board cover and these often distort over time and touch the fan blades. That is the common cause. The less common cause is the internal fans pinging off built up ice that should have been removed during the defrost cycle.

perhaps it's unhappy? I can't say i blame it, if I had to sit there all day in the freezing cold making ice I would moan too.
here's a list of possible problems
If it makes excessive noise:-
Problem and Likely Causes/ Probable Solutions

Fan blade vibrates Blade is bent Replace fan blade

Fan motor mount is broken Replace motor mount

Compressor vibrates Mounting loose Check mounting

Water pump vibrates Pump bearings worn Replace pump

Panels vibrate Mounting screws loose Tighten screws

and ice can groan as it expands, but that only applies to large icebergs

Is the compressor running? Is the condenser clean and the fan running? Is the fan inside running? Is there ice on the coil? Those are the first things I would check after I check to see that the plug has power and the temperature control is turned on.

There are several fans on your unit one on the top with the compressors, one inside the freezer, and one at the bottom. If you open the freezer and the noise gets louder or stops then you know it is the evaperater fan. Sometimes the bearings start to go and they make louder noise. Also check on the back wall for frost you could have a frosting problem and the fan blade is hitting on the ice

When you say "The items in the freezer are cold with some ice on them. I have tried emptying the ice tray, but that does not help." Is there literally ice from the ice bucket dripping on the food and refreezing, or is there a layer of frost on the food? the noise you are hearing is most likely due to the evaporator fan motor running at alternating low and high speeds. This is a variable speed motor, but there could be quite a few reasons why the motor is not rotating at regulated speeds. the fan motor itself, a faulty thermistor, you could also have an issue with your main control board, or least of all a wiring issue.
You would be wise to have it inspected by a reliable refrigerator repair service, to at least determine what the problem is for certain.

have a look behing your drws in the freezer it has probably started to freeze and the fan that blows the cold air around will have an ice build up. The noise you hear is the fan bashing against the ice. The fan is normally situated behind the panel in the freezer section.

Hope this helps

There are only two other parts in the freezer that can make noisei if your icemaker is off. The evaporator fan motor makes noise when ice builds up around it, and the blades start hitting the ice. It also makes noise when the bearings start to fail on the motor. Rarely, the evaporator will make noise when the freon is pumped through it, we will get all kinds of strange noises. This is not a problem usually as long as your termperatures are fine. To check these items out, you will have to remove the icemaker and the back inside panel in the freezer. With it off, you can pinpoint where the noise is coming from. If it is a bad evaporator fan motor, replace it. Good Luck, Appliance Specialists

hi
i had the same problem with mine,and fixed it very easily in about 10 minutes all you do is take all the shelves and draws out, then remove the light cover (one screw at the top)then the bulbs,there are three screws on this panel top middel and bottom,take these out,now gently pull the panel off,behind are two plugs unplug these and completly remove the panel.
next unscrew the water chiller at the bottom of the fridge and lay it in the botttom,take the deoderizer cartreges out and remove the two screws out from behind there,just two more screws at the bottom of the panel,there should be two plugs at the top of the panel,unplug these and remove the panel completley ,if like me you should find the fan all iced up, some warm water on a spunge should remove this and the fan should move freely if the ice is severe then remove the fan motor and run the panel under some hot water untill the ice is gone,assuming the motor is'nt burnt out this should cure it.if you want to test it plug the panel back in also the light panel ,and hold the light switch after about 30 seconds to a minute the fan should run,now just put it back together and thats it....

hope this helps

just about all friges work off the frezer .the evap fan moves the air fromthe frezer to the frig.so you would here fan noise.i dont know your brand but on most frezers if you turn the frezer temp to the highest setting thats acomplished by keeping the air from going to the frige.hence warmer frig temps .also make sure fan on out side back is working and condenser is clean.again turn air damper control from frezer to frige to lowest setting .somthimes this could be in frig section.God bless ,tom

Check the defrost timer, rotate it until a solid click is heard. If your unit starts to work replace that timer. Good Luck
