Product review (1 stars): Doesn't fit (but an earlier one did). No response from manufacturer
Disappointment.
Change in the design; no response from vendor
I purchased this in ~Jan 2017. I rec'd P/N 801797-r1. It worked like a champ.
I purchased this in Dec 2017 and rec'd what I'm sure is the same part # but unkown revision.  I returned it to Amazon who replaced it without question.
I rec'd P/N/ 801797-r5 in replacement.  It is clearly different in that its seat is higher in the attachment port.  It only engages with the receptical with some force. When you try to give the 1/4 turn to seat, it won't.  If I were to apply any more torque, it would almost surely damage the refrigerator.

What happened in that r5 isn't compatible with r1??
A phone call to the manufacturer (# on the label) went unreturned.

r6 should have the number removed.

Sending this back and trying something else.
