I have GE profile model #dpsq495et6ww dryer that makes a squeeking noise similar to a sound you would hear coming from a whale. When I shake the machine the noise goes away for a few minutes but then it comes back. Do you know what the cause of this is and how I can fix it?

It is a loose belt causing the sound. The belt could be too loose from wear. You can replace the belt if you wish but it's not a 5 minute deal to do.

I would bet you have a bad rear drum bearing. These bearings, when they fail, they make the most shrill sound you can imagine.

Usually support rollers and idler pulleys don't make this noise, and chances are, your front panel is a solid panel, not a split one. These bearings get packed with dirt, dust and lint which causes them to become dry and fail. It's inherent in its design, which you will understand if you decide to fix it.

Trust me, you need a rear bearing. The only hope you have is that you have noticed it before the bearing cradle is fried. If not, it doesn't really matter, because all the related parts come in the same package. If you're interested in doing it yourself, I can help you change it. Just let me know.

I have a GE Model DSWR405EB1WW that had the same problem. I did a search for my dryer parts, and found drawings, parts and pricing there that were very helpful. My squeaking noise was eliminated by replacing two of the "Slide Drum" nylon or plastic parts that showed >a lot< of wear. My biggest trouble was with getting to where they were, on the back of the front panel.

I'm not an expert, but I don't think your problem is with the belt. At the GE Appliances website, under "Dryer Noises", it said that "A frayed or damaged belt will make a thumping sound."
