Product review (5 stars): Part is the same as the original - works fine.
Download the manual for free before you buy this because the valve may be fine. I kept it and replaced it anyway even though my original was okay.  To test yours all you need is a multimeter to measure resistance on the coils and check for voltage getting to the solenoid when the condition(s) are met.  It was easy to change out, but watch out for the sharp metal frame that holds the assembly together, I cut my finger.
