I have been working on trying to fix a noise coming from this dryer.
It starts about 10-15 min into use. It is a humming/vibration noise that progressively gets louder. Sometimes it goes away for a min then starts again. Sometimes there is a bit of a rattle.
So far, I have eliminated the usual suspects. I removed the tub and the belt. I ran the motor without the anything attached to it. Sure enough 10 min and the noise starts. I cleaned out the blower, the fan and all the ducting. The blower looks in good shape. no breaks or cracks that I could see.
The motor shaft seems tight and spins easily. There is no play.
the rubber dealy holding the shaft in place looks in good shape.
It seems to work ok, but not being able to find and fix this noise is driving me nuts.
