I have a Sunsung RS21JLSG, and it's not chilling the food like it should. It's making terrible noise, sounds like a generator. Anyone know the problem?

No new washing machine should squeal and make a terrible noise when it washes. Call whoever you bought this from and have the fix or replace it.

If its not making ice then its just the fan the blows air to the icemaker compartment. This will not affect your food. The ice in your icebucket will melt though. I would empty it.

If by white noise do you mean the test tone generated by the receiver? If so, this is actually pink noise and it is internally generated by the receiver. I would make sure either in the menu or on the remote that you haven't accidently turned off the surrounds and double check the wiring to the surrounds. Good luck.

buy a new sound card

The first thing to check would be to make sure the power steering reservoir is not running near empty, locate the filler cap for the power steering pump it should be marked and then add the appropriate amount making sure you don't over fill, that may make the sound go away if not we must move on to the next possibility, by the way if the noise gets louder when you turn the steering wheel it is most likely the power steering pump or fluid level is low.

could need a new bearing

Actualy it can be front drive shaft,

Many sufferers make use of self-help treatments such as:

• Maskingthe tinnitus with competing sounds, such as low music (using personalheadphones) clocks, or other noises such as ‘white noise’ generators.This makes it easier to ignore the tinnitus, help concentration andsleep.
• Useof hearing aids for hearing loss - being able to hear sounds you cannotnormally hear may help override the tinnitus noise
• Cognitive behaviour therapy can help people to change their response and lower their awareness of tinnitus.
• Deliberately trying to concentrate on something else and to ignore the tinnitus
• Stress management - stress and fatigue can make the condition worse.
• Avoidance of alcohol, nicotine, caffeine, and certain foods that are known to aggravate tinnitus.
• Use of earplugs, earmuffs and avoiding loud noise to limit further damage to the ears.

If it's metallic sound you are loosing teeth on a gear or two.  This is caused by lack of lubricant or simply fatigue of the material of the gears.  Don't use it, you can get metal flakes in your food.

Take it in to a repair shop and have it fixed.  The money spent is well worth it because if done correctly will last another 12 years.
