Makes squealing noice when turned on

My monitor is making a weird noise when I turn it on. I is kind of a squealing noise. It does it for about 4-5 minutes and then it stops and is fine until I turn it off and turn it back on again later. Other than that it seems to be working fine. Any ideas??

When I turn heater on it makes loud noise & wont heat up


Paula, it sounds like your heater fan motor has died and gone to heaven. You did not describe the noise but if it's kind of a squealing noise you need a new motor installed. Should be under $300.

DW makes a lot of noice when it's washing....squealy, whiney noice...very loud.


Hello Summer Summer - Often if the dishwasher is making a loud, squealing noise then it is recommended for the wash motor to be replaced. If this problem persists, you can locate a certified technician directly through the manufacturer website or in your local directly to determine what may be causing the issue at hand.

Exhaust Fan makes noise


Check to make sure that nothing is obstructing the fan blade causing the noise, if not then the bearings in the fan motor are more than likely going out causing the metal on metal noise.

My 92 4 runner makes a squealing noise when I turn. It only makes the noise when I start to accelerate in the beginning of turning. If I slow down on the gas the noise stops alot quicker, then if I keep on...


Most likely need to replace you accessory drive belt. However, before you do that make sure the tensioner is bringing adequate pressure to bear on the belt. The squealing is probably the side of the belt slipping in the metal drive pulleys.

How do i turn off the high pitched frequency noise


If what we are talking about here an old model of monitor that has a bulky back, the high pitched frequency is caused by other electronic devices such as your speakers.

- Relocate your speakers away from the monitor
- do a factory reset on all settings on the monitor or if possible, do a degauss.

Samsung 2253bw lcd monitor makes loud, fast ticking noise > 10hz. Noise occurs even when monitor is powered off with switch.


Turned out ticking noise was harmonic vibration triggered by a nearby airconditioning compressor. Once I guessed the cause, putting a rubber pad under the monitor to dampen the vibrations eliminated the ticking. Removing the pad caused the ticking to reoccur. Ditto with turning the A/C off or on. Weird!
