I have images that are 3 by 2 aspect ratio. The images are of products. I am removing the backgrounds and then replacing them with pure white. What I would like to be able to do automatically is trim the edges of the images down to the top and bottom edges of the products but keep the aspect ratio. I know I can crop down to the products manually but I have many many products to do and every little bit of time savings is important. Thanks in advance for your help!!

try this script

var d = new ActionDescriptor();
var r = new ActionReference();
r.putClass(stringIDToTypeID("adjustmentLayer"));
d.putReference(stringIDToTypeID("null"), r);
var d1 = new ActionDescriptor();

d2.putEnumerated(stringIDToTypeID("presetKind"), stringIDToTypeID("presetKindType"), stringIDToTypeID("presetKindDefault"));
var list = new ActionList();
var d3 = new ActionDescriptor();
var r1 = new ActionReference();

I believe that I found the issue. I have updated to a new version, please try this new action and trash the first one:
Once again thanks so much for all your time and effort!!! The action works some times but not other. Look at these screen shots. In the first one it is perfect!! In the second one it does not crop down close enough to the image and it changes that aspect ratio.
When I use @r-bin script if I select the subject first then run the script I works flawlessly. If I don't select the subject first the script will sometimes crop in the the content slightly. But I am all about finding different ways to do this. Here are some sample images to test with. 
Try removing the step of adding the Levels layer and then the step of removing this layer after the Trim procedure. The temporary correction was made because your background is not all white in the screenshots, artifacts are encountered. To eliminate them, temporary image correction is applied. But if the object is lighter than 128 levels, then its borders will suffer with such correction.
Thank you for the sample images, they do help over screenshots.
I can now see why some images work and others don't. Some images are invalid for your rule of 3:2 landscape when the image is cropped top and bottom. It doesn't matter that they start 3:2 landscape, the issue is what ratio they become when cropped top and bottom...
You can see in the screenshots that some product portrait content is under a 3:2 landscape aspect ratio, so the width can be extended to 3:2 while cropping to the top and bottom of the product.
However, there are other images with landscape content widths greater than 3, which means that cropping the content would be required if you still wanted the white space cropped at the top and bottom. As you don't want the image content cropped away, the final image can't be 3:2 and also cropped at the top and bottom to the content! You have competing criteria.
This is why a simple action was inconsistent. A conditional action would be needed to use logic, processing portrait and landscape content differently.
Each part is a different shape so the crop needs to be different each time.

An appropriately composed action can account for the variable nature of each image.
