Product review (5 stars): Perfect replacement BUT watch the installation video first
Had this in for a month now and it's been working just fine.  Easy install (after watching a youtube video).  If you're just a regular guy and not appliance repairman you should go to youtube and look up the installation videos for this design Whirlpool timer.  Do NOT follow the directions for an almost the same timer, find the video for this design. Saved me from breaking things.  Seriously, watch a video, it'll save you a lot of time and frustration.  Hint, the problem is in the friggin' timer knob removal.  Do NOT force it, watch the video.  Much easier!  LOL. Very happy with this purchase.
