FFRE123WAE1 Electrolux Air Conditioner - Instructions

Purchased part number 5304476793. Part was not the right size, so called Electrolux (877-435-3287). After 50 minutes on hold, I was told this IS the correct part.
When I explained that it is 1/2" too tall, and 1 1/2" too narrow, and none of the slots line up, she would only say (again) that it was the correct part, and their drawing ... Read more was correct.
And left me hanging. No discussion, no mention that maybe the wrong part was in the packing. No options. Thank you for calling. Goodbye.
At least PartsSelect was prompt and courteous, and gave me a refund, since the manufacturer was not at all interested in the issue.
