Product review (2 stars): Not quite the right size, despite the part #
At first I though it was a great solution, a replacement for a stupid plastic part that would otherwise have required replacement of the entire Microwave.  Unfortunately, it is obviously not exactly the correct size, as it is MUCH louder in clicking into place, spontaneously results in triggering the microwave on closing, and now is dragging the trim out of alignment.

On to replace the microwave after all!
