Thank you for your question. It is concerning when the refrigerator is not functioning correctly.
This is a problem that will require some experimentation, The new filter will fit, you may need to wiggle it around and incrementally try to line the new filter up, but it will fit.
Here are the manufacturing comments.
Unfortunately, a few consumers have returned the new design stating that it
does not fit. We suspect that they are reaching this conclusion after
experiencing some difficulty and then noticing that the “new filter” looks slightly
different than the one they removed.
In reality, the new design is no more difficult to insert than the previous
design. Unfortunately, both can require more than one attempt to engage
If experiencing difficulty, consumers should remove the grill from their
refrigerator to allow for easier access to the filter housing. If necessary,
reinsert the filter at different rotations until the filter engages properly.
I hope this is helpful. If I may be of further assistance please include more details in a reply to this entry below.
