Noisy Dryer w/Heavy load, no noise w/light load
Model: GE DHDSR46EE1WW. I have replaced the four glides (all white, as the shop told me no reason to pay more for the green ones) and the bearing in the back. Dryer works fine w/light loads, but more than that the noise is horrible. What next?
There are two other things that are fairly common that can cause this. One is the idler pulley. The idler pulley is the pulley that puts tension on the belt and often it will squeal under a load. The other is the blower wheel; often the clamp that holds the blower onto the motor will become loose. Most of the time all you have to do is tighten it up and the noise will go away.
There are a couple of other things that can cause this but they are much less common. In the front of the dryer at the bottom (opposite of the front top slides) there is a felt strip that goes halfway around the bottom. If the felt come off of place the drum can come forward enough to rub metal to metal in the front. Also I have seen a screw, penny or something similar stuck in the felt. Also there is a chance the motor is bad but that would be the last thing I would check and it will be hard to confirm.
