Product review (5 stars): Everything works like a charm now
This knob fit my GE dryer perfectly.

There was a bit more work involved in replacing it as a metal ring was still attached to the base of the stud this knob fits onto. I had to remove the back screws of the instrument panel face. Once removed I unplugged a small electric switch, removed the ring, fit everything back together, and stuck this new knob right on. Everything works like a charm now!
