Our GE Dryer, model DPSB613GD1WW, has developed a fairly loud and very annoying squeak. I believe that it makes the noise in sync with the rotation of the drum, it is very regular taking just over one second per squeak. It is louder with a full load of clothes, not as pronounced with a half load. The noise level diminishes after ten minutes or so, and after about fifteen to twenty minutes it is very faint. Hoping someone can lead me to the cause and the cure.
