I have a relatively new refrigerator. It has an icemaker with a water filter, and the filter needs to be replaced regularly. The owners manual clearly gives part numbers of the filters needed to replace.
When I look for those part numbers online, I see LOTS of third party filters that claim to be compatible. Being a suspicious person, I looked at reviews, especially the most negative reviews, and find a curious thing. So far, although I have not tried to look at EVERY imitation, each one has recent comments that indicate the device *used* to work, but that recent purchases no longer work. To the point of damaging the filter assembly so that NO filters fit - you then need to repair the whole assembly, costing several hundred dollars.
WHY?!?!?! why would a manufacturer *change the part's design* without bothering to note that in the product description? At least some of the reviewers post photos that clearly show a difference in the way the filter connects. Do they think that there are so many imitation parts that no-one will damage their reputation? Did the original appliance manufacturer commit espionage to make all the cheap competitors obviously a bad buy?
I could see the OEM changing the design of the filter for newly sold models, but this is a case of a replacement part working at first, the not working when purchased again.
grrrr.
