Why does my bed make a lot of noise


Most systems have cheap fans with cheap bearings that wear out easily. It may be time to replace the fan.

Redcore heater fan makes alot of noise is there a fix for it


DON'T KNOW WHAT TO TELL YOU, EXCEPT THAT I AGREE THAT THE BEARING IS MOST LIKELY THE CULPRIT, BEARINGS SHOULD NOT BE MADE OF PLASTIC AS HEAT CAUSED BY FRICTION WILL DEFORM IF NOT MELT IT.

Noisey like a bearing going out. can i replace fan bearing or whatever bearing it is.


Modern air conditioners do not allow 'bearings to be changed.'

These days - you can't even 'oil' them (as in the old days).

Basically, when bearings go out - you have to replace the motor.

Be 'sure' it is a bearing noise and not the fan blade hitting the unit.

Also - it's possible (but not likely) that it's the bearings in the compressor making the noise.

If you're not sure - you will need to run the fan by itself. Just turn the switch to "FAN ONLY." If it still makes the noise then it's the fan.

Hope this helps.

My computer is becoming really hot and noisy. After turning on the computer, everything is good (no noise). Once around 15 minutes passes by or I open up a lot of programs together, my computer starts...


Sounds like the fan is wearing out, as it heats up the fan needs to spin faster and if the bearings are wearing out it will start getting louder and it will also get hotter because the fan cannot keep up the heat being produced. You can replace the fan, most computer shops will carry replacements, also get a can of compressed air and give the inside of the computer a good cleaning. This will help keep things cooler as well. Also make sure that the air vents on the outside of the case are clear as well.

Fan started making noise


I have one of these, and every so often, the fan would start making a loud clicking noise. I discovered that if I shut the fridge off for a while and left the door open to defrost it, it'd work fine again for a while before the noise came back. Apparently, some ice was building up between the metal heat-sink and the fan, causing the fan blades to scrape against the ice/frost build-up and make the "tick, tick tick" noise.
There is no compressor in the Avanti EC15W-2 mini fridge. It uses a simple Peltier junction device to transfer heat from the inside of the fridge to the outside/rear of the unit. So it should never get very loud at all, unless one of the two fans in it is acting up in some way.

The fan makes a lot of noise.


The fan's motor bearing is shot.  You have to replace the whole fan motor unit.  There is a good exploced drawing of unit.  Google Frigidaire publication #  5995342655.   The part number you need is: 216690400.  The unit can be accessed by removing the stainless cover at the top of the inside of the refrigerator.  There are 4 stainless, philips head screws to remove and then the cover pulls down.
Good luck!

York HVAC unit fan is making a lot of noise. Hot air down come out, and in the summer coll air did come out, but the fan is loud. Thanks


If your fan is making noise the blade or blower wheel is either hitting something or the bearings in the motor are bad and the motor needs to be replaced.
