Every 20 minutes, my freezer would make a crackling like noise. What does this mean and how can I fix this?


Refrigerators are not the most complicated appliance in the house, but it still takes a lot of parts working together perfectly to keep your food cold. If one of those parts breaks down, or begins to, you may start to hear new noises from your refrigerator. Fridges make some noise during regular operation, but if it suddenly gets louder or makes a different noise, it is a good sign that something is wrong.

Freezer Fan
Freezers can be located on either side of the refrigerator, or may be at the top or the bottom of the unit. If you hear a noise coming from the area in which the freezer is located, you should open the freezer and see if the noise gets louder. Any squealing sounds coming from this area indicate a broken freezer fan. These units are not designed to be repaired, and eventually one making a loud noise will break and need replacement.

Condenser Fan
All motors typically require a fan in order to maintain a safe operating temperature. Like the fan in the freezer, the fan that runs on the condenser can also break down and create a similar squealing noise. The location of the fan noise is what differentiates the freezer and condenser fan problems. If you hear a fan noise coming from the lower part of the fridge at the rear, it is likely the condenser fan causing the problem.

Action to do
Open the freezer to see if the noise gets louder. If the noise becomes louder with the freezer open, the noise is likely caused by the evaporator fan. If the evaporator fan is the culprit, replace it to get rid of the noise.

Pull the refrigerator away from the wall, and check the condenser fan at the back of the fridge. A metal panel may cover the fan, which can be unscrewed. Listen to see if the fan is the source of the noise. If it is, the fan may need to be cleaned or replaced.

Thanks for using FixYa.

Good day ! : )

Kitcheaid refrigerator is emitting a high pitched noise. intermittent but presistent, noise is on more than off.


Without being able to hear the sound or knowing your model number, it will be hard to provide an accurate diagnosis. There are few parts that move in a fridge - and presumably it is one of those that is the source. The first are the fans. Nearly all modern fridges have evaporator fans and condenser fans. A squealing fan will eventually fail and may end up costing more to repair if allowed to continue for a long period of time.

The evaporator fan(s) are usually located very near or in the freezer compartment, and are operated by the the thermostat in the fresh food compartment. If the noise is louder with the freezer or fresh food compartment doors open, it is probably this fan(s). When it is noisy, adjust the thermostat to a warmer temperature and wait a couple of minutes for the sound to stop. If it stops, adjust the temperature to a colder point and listen for the squeal to start again. This will help confirm it is probably the fan(s). Accessing the fan(s) is usually done by emptying the freezer and removing the back wall - sometimes the fan(s) are in the fresh food compartment towards the back close to the freezer compartment behind a protective cover or trim piece. These fans normally need to be replaced as there are few replaceable parts.

The condenser fan is located on the bottom and is usually visible from the rear after removing a cardboard / fiberboard cover. Check the be sure that the fan blades are spinning with the motor - and not slipping on the motor shaft. If it appears to be ok, you might be able to determine that the bearings are the source of the noise. You may or may not be able to add lubricant to restore quiet operation - based on whether or not the motor provides a place to add lubricant. A good cleaning may restore balance to the blades and quiet the motor down. You might also be able to allow a drop or two of machine oil to fall on the shaft between the fan blade and the motor itself.

If the source of the sound can't be determined - it may be the compressor. A failing compressor could be a costly repair. The "compressor" is a hermetically sealed assembly consisting of a motor and compressor, and is also located at the bottom - near the condenser fan. This "compressor" is not repairable (because it is sealed), it must be replaced as a whole.

If you want more help - please provide your model number. I hope this helps & good luck!

The Sound used to increase over a few hours. NOW the machine starts up REVED.... When you turn it on after letting it cool, it's silent until you start Windows, and the noise picks up a little. You...


Hello there! Noisy Sounds can be much frightening, but if you could determine from where the sound is coming on you will get the solution, the sound makers inside a pc are mostly fans, and what type of sound you are actually hearing, rattling sounds means some wires touching up the C.P.U Cooler fan, another one could be a loose fan on the SMPS. Solution to this is to Check all the Fans Do so by
1. Remove the Cabinet cover on one side and Start the machine and try to see and determine what actually is making the noise, rattling sound could be a wire or something touching the fan, if its okay, then listen for the SMPS fan.
Hope this Helps.

I have an IBM x346 eserver that has run well for years. The fans are now very load (whirling noise). I typically only hear this noise when the room temp is high, but this server is in a cool room with no...


It sound like the CPU fan or server case fan/s or power supply fan bearings are worn.
To determine which fan/s is faulty open the computer case and stop each fan from spinning, one at a time to determine the noisy fan. Once you have identified the noisy fan then replace that fan.

Weatherking heat pump sounds noisy but has a 20 degree air difference from intake to vents, is this normal?


Without hearing the "noise" it is difficult to diagnose via internet; however, I can tell you that the 20 degF temperature difference is a good sign.

If the noise is at the outdoor unit, try to determine if it is the casing or something else. Sometimes the casing can rattle and/or vibrate that can cause a sound. Sounds can also come from refrigerant lines rubbing against the casing. Other noise sources at the outdoor unit are the fan motor, fan blade assembly, and compressor. You can remove one of the fan motor wires from the contactor, tape off the end, and start up the unit for a few seconds to see if the noise is still present. Then you can replace the wire and remove the compressor wires from the contactor and repeat the test. This will help you determine where the sound is coming from.
If the sound is coming from your indoor unitl, the most common sources are loose tape, Blower wheel, blower motor, or blower housing. Also look for loose panels.

Without being onsite with toolbox in hand and being able to actually hear the sound, I hope you find this information to be helpful to you moving forward. :-)

Computer noise


More likely one of the fans, but could be the hard drive. Open the case and listen. Fan on power supply, fan on processor, or hard drive are the most likely sources of the noise. Processor fans and power supplies are both cheap and easy to replace. Hard drive is a bit more expensive and you must back it up (which you already regularly do, right?) if you want to keep your data.

My computer makes a loud noise,how can I fix this problem please?


there are a limited number of things that could be making noises. take off the cover of your computer and listen close when you start it. A fan would be the first thing i'de suspect. check them all- cpu fan- motherboard fan-videocard fan- powersupply fan.
I would also listen to the powersupply (rear top of computer)
only things left to check that could be making noise are the cd/dvd rom, floppy drive (both wont run without a disk in them) and your hard drive which would be the last one to make noise. the hard drive runs everytime your computer moves data, if it is getting loud, i would suggest backing up important files and shopping for a new one. Post again here if I can be of further assistance.
Regards..

Whining sound with xion 800 watt power supply.


There is a fan insine the power supply, and also a fan on the CPU. Occasionally there is also a fan on the chassis of the computer itself.

Turn on the computer, take the case off, and listen to identify the source of the noise. If it's inside the PSU, return it and get a new one.

Noise inside cabinet


FIRSTLY if you have warrenty use it if not use the following steps .Open up your computer DONT TOUCH ANYTHING INSIDE , discharge yourself by touching an unpainted surface then proceed, turn on the pc Sound can vary one way that you can determine the source of noise is stoppping the fans whilst it is on one by one to determine the source.you can remove the cd /dvd from any optical drive (dvd cd drive) .And 2nd you could tell if the hard drive is crashing if you hear a reoccuring clicking sound or a whirr of which the hard drive is crashing.Depending on your manufacturer of hard drive download their hard drive diagnostics program and check for bad sectors if there is an increasing number of it occuring then your hard drive would definately be in trouble.Any sign of this vibration can be caused by vibration so try to keep all the screws tightened .
