Product review (1 stars): Sent wrong timer!
Looks to me like they sent the wrong timer. I ordered WE4M533, but by the looks of it I received WE4M527. Although they look very similar and actually hook up the same the dryer knob does not fit on this timer. My original knob is fine, not broke and fits just fine on my old timer.  I'm afraid if I try to reorder the right timer that I will once again get the wrong timer.  It would be nice to actually be able to talk to someone from the company. You can see the difference in the pics.  The one on the left is my original timer. Even different in height.
