I posted about one year ago warning that ge fridges use a custom chipped water filter that shuts down when they think it has done enough. Aftermarket makers do not have the chip and will not work. Ge wants over $50 for a filter. I bought some from ebay but genuine factory made.
I had to replace the filter today. It could not read the chip in 3 of 4 I tried. I doubt ge will replace them with good filters. So one working filter costs about $80 -400 once a year!
