SOURCE: fan making high pitch sound,

If you are confirmed with the noise coming out of the fan unit, then please do not waste much time but open the front panel and look into the air flow slot if there is any foreign particles struck inside.You will need to get access if the sound is coming from the rotary fan as sometimes some objecct would have got struck into the vanes of the fan. Once it is confirmed as when you switch off the sound reduces and on switch on the sound increases, then it is confirmed and removing the front panel unit becomes important. Be careful with the connecting lines so as not to break the cooling pipes if you are able to do without removing .
Hope you start with the first part and dislodge any particles by an extended probe. Hope I could help. Good day

SOURCE: Once you turn on aircon

Your AC needs a good overhauling as the fan seems struck on the bearings or the blades are rubbing the sides. Also the compressor fails to cool as there can be low gas, low pumping pressure or a blocked condenser.
You need to remove clean the coils and lubricate the fan to be set back. Check the capacitor to the fan and compressor as a low value will reduce the speed and so reduce pumping pressure.

Try to better describe the noise.
Is it a
scraping of metal
grinding / rubbing
high pitched shriek like a drive belt slipping
Is it
underneath the body
under the hood
in the aircon
when you pull into gear
when you pull away
etc
Do a bit of detective work and come back.

Maytag electric dryer is making a high pitched noise


The squealing noise is from the belt tensioner. Replace the pulley only on the tensioner along with a new belt. The bearing in the pulley is causing the squeal. Sears will sell this in a kit. The top and the front panel of the dryer will have to be removed to replace these parts

The high pitched sound could be from the evap fan motor. If you can get to it a drop of silicon oil would solve the problem.

Pitched noise coming from the fan


When I first got my PS3, It had the annoying high pitched fan sound as well, but went away after a week and has worked fine ever since, no problems at all. I have the 60 gig version, so. Maybe if yours is new you just need to break it in?
