Product review (5 stars): Perfect fit, works fine - plus notes on the handle vs non-handle version
This door latch was a perfect fit for our Jenn Air JDB1090AWS.  Total time for replacement was 15 minutes, give yourself 30 if you aren't accustomed to working on your appliances, but it is a job that anyone should be able to perform.  Be sure that you turn off the power to the dishwasher at your breaker box before you start.
Hint - search for W10275768 on YouTube and pick the video from Appliance Parts Pros (easy peasy).

Do you need this part (without the handle) or the assembly (with the handle)?

If the door on your dishwasher is opened and closed by simply pulling or pushing on a towel bar, this is the correct part.  See attached photo of KitchenAid dishwasher with towel bar for an example.

If the door on your dishwasher is opened by using your fingers to pull/compress a latch/handle on the face of the dishwasher, you will need the assembly with the handle.  See attached photo of Frigidaire dishwasher with a handle/latch on the face of the control panel for an example.

Don't let the bad ratings left by other reviewers discourage you, they received the exact part that they ordered.  This is the part that is depicted in the photo and description.
