Product review (4 stars): Great price!
Bought this timer and it fixed the problem with the knob not advancing (motor timer failure).  Original timer (motor) failed after 14 months.  The part I received (and the box) was marked with the original part number W10634750.  Note that the picture also shows the original part number.  Whirlpool information indicates new part number is W10846428 superseding the old.  Not sure why timer number was revised by Whirlpool but could be due to improvements in reliability.  I strongly suggest the seller indicate that this is the old part, not the new one OR supply the new part!  We'll see how long this timer lasts.  Great price!
