Product review (5 stars): Perfect Replacement
The door latch on my Jenn-Air failed and the door wouldn't stay latched anymore.  Another website I found is excellent at directing you to the correct part for pretty much anything on the dishwasher.  They also sell this part, but at a higher price.  In fact, it is generally a good idea to shop around the internet for dishwasher parts in general,  Costs vary considerably among vendors.

This part was an exact match and a relatively easy do-it-yourself project, especially for someone like me who isn't mechanically inclined.  Most time-consuming part was taking off the inner door panel and putting it back on.  Other than that you just lift out the old latch, disconnect the wires from each side, connect them to the new latch, stick it in and put the door panel back on.  15-30 minutes, depending on how handy you are.

It's been over a month and the latch works fine.

Note:  This latch is for dishwashers that do NOT utilize an external latch handle.
