DRYER BUZZING NOISE - Dryer For Sale

Happens when the bearings in the fan or compressor motor are getting worn out. make sure there isn't a piece of cardboard cowling or debris hitting the fan.

I would suspect there is something stuck in either your wash motor or drain pump. If the noise happens throughout the whole cycle, it's likely the wash motor, but if it only happens on start up and periodically thoughtout the cycle, it's the drain pump. The drain pumps are known however to get noiser after a few months, in which case I would have the drain pump replaced.

If everything is working as it should - the problem may be with the motor.
Either the starter is starting to fail, or it may have gotten wet. Check for leaks around the base, and be prepared to eventually replace the motor.
If you can deal with the humming, there is no reason to replace it at this time, and there is nothing you can do to quiet the noise.

Thanks for using FixYa!

Sounds like you may have a motor issue, they can get lint trapped inside, and it causes the motor to overheat, and eventually go out. You can remove the top, then the front, and see if thats the problem. Usually, once the motor starts making noise, its time to replace. Right now, the packings in the motor are cold, and once they heat up, they stop making noise, so it could last quite a while.

if you have ice buildup then the fridge may be low on freon.
or there is dust clogging around the pump or fan is not running.
remove the bottom or back and look around the compressor.
see that the fan is running.

Had same problem. cooling fan was going out.Replaced fan about a year ago and now it is going out again. Am ordering another fan now

How deep do you want to get into this?It sounds like the wash pump motor bearings that are worn.You can pull the unit out flip it over and wd40 the bearings in the motor or you can replace the bearings.Try to lube them first.

these units have a condensor cooling fan in the rear it appears that yours may be seized up.
