    Ghost like whistling comes from the fan in the freezer portion. Seems to go awayh when the fan is running faster.

  • guesty Nov 18, 2007

    It is the most irritating whining/whistle sound, sporadic, and LOUD! Sometimes it turns off- ah, silence, but later- it COMES BACK! All noise is coming from the upper part of the freezer- near the ice bucket/maker

  • marc m Dec 02, 2007

    This is a newly discovered problem for our 3 year old unit.

    The whistling is different than what is described in the manual. I am seeing some condensation ice (minimal) on the louvered back panel in front of the evap fan. I'm surprised it hasn't been eliminated yet from a defrost cycle. I'm going to try slightly changing the freezer compartment temp to see if indeed ice buildup is causing this.


  • smith75 Dec 13, 2007

    I have been dealing with the same whistling noise as described in all the other notes. It is definately coming from the fan but I have no idea how to get it to stop. Any suggestions would be appreciated.

    The whining noise is the least of our problems with this horrible
    model, I could live with a little noise. Our problem is that we have
    lost everything in both the freezer and the refrigerator 3 times now.
    Every year we have to have someone come out and fix the refrigerator.
    The whole thing just stops working and all the food gets warm and
    spoiled. Every time we get it fixed it costs us more money because they
    claim the problem isn't covered , even though it's been the exact same
    problem each time. We started having trouble with this refrigerator
    even before the first year was up.Don't buy this model!

    I have the same problem with a new fridge. Since I first got it, it emits this annoying whistle that I can hear in other rooms of my apartment. It's extremely annoying. It seems to be coming from the freezer, because when I open the freezer door for a small length of time, it stops. Now, it'll start up awhile later again, but there's definitely a freezer connection. I've had the freezer fan replaced, and the problem persists, so even though I thought it was the fan, I know now that it's not. Anyone else have any ideas?

  • GoingNutsmf Mar 01, 2008

    I have a new GE #PTS25LHSAR BB top freezer refrigerator that is absolutely driving me nuts because it whines continuously. I was told by repairman that it is the normal sound of a high energy efficient motor. (He also said woman can hear it more that men because of the pitch.) My daughter has a new energy efficient Fridgedaire Side by Side and it does not whine like mine. If I had known what it sound like before, I would never have purchased it. I have had it 1 1/2 mos and can't stand to go into the kitchen because the sound drives me nuts. Can someone help me. MF

  • Anonymous Mar 21, 2008

    Our refrigerator was purchased July 2004 and only recently started emitting a whining noise. Since this is a recent problem it doesn't seem that this is a characteristic of a high energy efficient motor or we would have noticed this 3 1/2 years ago. We've tried turning off the water supply to the ice maker and water dispenser, but that doesn't eliminate the whining noise. Any suggestions for a solution would be greatly appreciated.

  • aroo May 24, 2008

    I have a Bosch fridge freezer.



    The fridge has begun to emit an annoying whistling sound for a few seconds after each time you close the fridge door.



    Any ideas appreciated

  • Anonymous May 26, 2008

    I have the same problem. It happens when the ice maker is very full. I just empty the ice container and the noise stops the first time the pipe refills with water to make more ice. This will fix it for a month or so.

  • jjjooo May 28, 2008

    aroo -- please post if you get your bosch problem resolved.



    We have the same problem with our bosch integra column fridge -- sound is absolutely annoying, high-pitched, incessant... It's brand new --> and we just called for our second service call. Would love to get to a solution as fridge was expensive and we already built the custom cabinets, doors,...so no turning back for us.

  • defunct Apr 23, 2009

    This information was helpful to me. The fan in the freezer woke me up at 12:30 am, and I took the back of (from inside the freezer compartment) to get  the fan out  to replace it. Plugged it back in to keek everything cold, but will get a new fan tomorrow. Glad I found this. 

  • ebuck May 23, 2009

    Same problem: whine that goes up and down a little is coming from behind the ice maker in the freezer side. It's not as loud from the outsider. Open the freezer door and hear it much better. It's got to be a fan.

The whining and/or whistling noise is caused by a problem with the MAIN CONTROL BOARD, not, the variable speed fan motor. You can change the fan motor and the related thermistors and the problem will persist. The Main CONTROL BOARD is located on the back of the refrigerator behind a panel with from 3 to 10 quarter inch hex head screws. All of the of the connections to the board are normally easy to remove and re-install on the new board. I have had some new boards with bent pins, so, be careful when trying to put the plugs on the pins. Also, you can not get the plug configuration wrong, since, every plug has a specific number of pin holes. The board itself has 4 white nylon pins holding it to the refrigerator. These pins have a side that you must push in to release the board. I use a tiny screwdriver for the job. As you might be able to tell, I do this for a living, but, not on a paid per job basis. I work at a large apartment complex with all G/E appliances. Please unplug the refrigerator before performing any the the above actions. The Main Control Board is the source of many other problems, such as, Compressor not running, Ice and Water through the door problems and defrosting of the evaporator coil. Don't let a repairman condemn a compressor before it is proven to be defective.

We had to have a forklift to get this refrigerator into our house; now all we would like to do is shoot it and push it off the balcony! We have been tortured by the intermittent whistling for months and it is driving us crazy. If the noise, which apparently cannot be fixed, is causing undue stress and diminishing the quality of life for others out there, together, we may have a class action suit brewing. If for nothing else, to get a replacement appliance that does not whistle while it works!

Our freezer makes a noise similar to what you have described here from time to time. Each time it's happened has been when the bucket holding the ice from the automatic ice maker is filled to capacity. I remove the bucket, get rid of some of the ice, replace bucket. Noise stops shortly after :)

Not very scientific but something to try! Hope that helps.

One of the capacitors on the fridge's motherboard which controls the freezer fan speed is dying (i.e. instead of delivering a constant electricity supply, it delivers varying amounts of electricity) causing the fan speed to continuously speed up and slow down, the reason for the whining. You need to replace the motherboard (unless you're a techy and somehow are able to identify and replace which capacitor is faulty on the motherboard, much too involved for me, anyway). GE will do so at a "discounted" price (in the States) of $290, the repairman/woman will be in and out of your kitchen in less than half an hour, having installed a new and upgraded motherboard. The whining on my fridge is gone and the fridge is practically silent now whe and operates normally.

    I have this noise and noticed when I took everything out where I could see the fan blade that it is speeding up and down intermittently. I was thinking it was the motor or fan blade itself but this makes sense.

I have this same model and it makes this noise when the controller slows down the fan. It is a resonance which I think is caused by the fan blades themselves.  I took the fan motor out and lubed it bearings to be sure they were ok but that had no effect.   I will probably go back in to check the position of the fan blade on the motor shaft?  Can't think of any thing else to try.  I think the noise goes away when you turn it off and on because the controller starts the fan at a higher speed after being shut off?   The only other thing I could suspect is some type of resonance in evaporator?  It is a very weird sound.  Like a ghost in your fridge.

The problem is that the ice maker leaks ice often, and it collects around the fan, making the fan inoperable. This causes the whine noise. The only solution is to chip the ice away in the back by the fan, which requires emptying the freezer. This is the worst refrigerator we have ever owned.

I had a similar problem. It was a fan in the back of the freezer unit. I disconnected it electrically after pretty much ripping the back panel off the freezer in a late night bought of frustration. (from the inside.)
I'm guessing the fan had blown a bearing. No word yet if my fridge will work efficiently without it...

Have a GE Refrigerator GSH25JST - 3 years old. Same problem - high pitched intermittent whining. Initally thought is was the fan. Called out GE repair. The whining sound was not happening when they showed up but he noted the fan seemed to be pulsating in and out. They replaced the motherboard which is on the back. That did the trick. Explained something about energy efficency and the motherboards are suppose to regulate the fan, etc. Watched him simply plug in the new motherboard - nothing to it. I said that no one should have to replace something that on a 3 year old refrigerator. Total service call - $100 including motherboard part. GE repair man said that normally it would be a $400 repair but they would discount it. Refrigerator working great now.

The owners manuals usually have a "what's that noise" section since Refers make all kinds of creaks, groans and moans these days due to refrigerant flow, ice making operations, defrost cycles, etc. Lots of noises possible. Check also for the drip pans underneath vibrating, that can drive you nuts too. Make sure all the metal tubes, etc. are not rubbing anywhere and vibrating. It will take a little flashlight and on your belly work but check mostly the underneath area by the compressor area for things vibrating, etc.

I had a high pitch whistle coming from my lg f.f. which continued when switched off.
I emptied the ice compartment, but it didnt help, I switched it off for 20 mins, that didnt help,
I checked the water filter that didnt help, but i found a small plastic item on top, which was the
receiver for our wireless door bell, that was the guilty party.Changed the batteries, and peace at last.

The problem comes from the fan. I believe a build up of condensed moisture cuases the sound when the fan gets turned on intermittently. . If you fold a piece of paper and grind into the fan with it it seems to lessen. the real solution however would be to coat the fan with something that would make it quieter. i have to take the grate off and see what to do. it is annoying. dan mccarthy [email protected]

I bought this ge refrig because it was advertised as 'very quiet'... but it moans and groans... repair tech basically said it's the coolant doing it's job... I'll ask another opinion soon... very frustrating.

Nice, you take the time to help and get "dissed." My guess was something rubbing the fan blade or associated with its vibration, that changes shape when it cools a bit, but i'm not a pro...

SOURCE: My freezer is making this high pitch noise, its an industrial Beaufort freezer on wheels

Zaria:
I have the same kind of fridge and it also makes this kind of noises, however, they are on the acceptable level. They sound more like a seal being happy with the new food. It is not all the time but sometimes. I think it is the contraction and expansion of the pipes that cause the noise and is not a sign of any problem. Of course all depends on the level of the noise you have...
Hope it helps. Greg.

RCA F32650 production May 2003. Was working fine. Turned it on the next day, got no picture and a high pitched whining noise.  Please let me know what I should do to fix it.


If it weren't for the high pitch whining noise. I would say it probably is an internal fuse inside the chasis. It is rated at 1.5 to 2.0 amps. With the whining noise it sounds like a trouble shooting bench
job. Problems occur when a electrical/electronics device is turned on and turned off. Inrush voltage,
when it is turned on, can go up to three times more than normal. This also happens at turn off. Solid state components usually fail at this time. I don't feel that this is a problem that can be fixed in the home.---BBB
